SegTurn User Guide (Ver 1.10) Home

Overview

SegTurn is a Microsoft Windows program that makes it easy to design segmented wood turning projects from bowls to vases. Starting from a simple design defined with basic parameters you continually make changes until you are satisfied with the design. As you are making changes a 3D image of the design is updated so you can immediately see what the final result will look like.

The program can be used to create traditional segmented vessels or 'Painted' segmented vessels. You can also combine elements of each within the same vessel. A traditional segmented vesel has a small number of segments in each ring and many of the segments are similar and the vessel typically has a feature ring. A 'Painted' segmented vessel has a large number of thin rings with a large number of segments per ring. This allows a pattern to to be created over the entire surface through the placement of segments made out of different woods.

It is assumed that you have a general understanding of the basic concepts involved in constructing segmented vessels. If that is not the case I recommend reading some of the many excellent books on the subject such as ‘Woodturning with Ray Allen’ by Dale L. Nish and ‘The Art of Segmented Wood Turning’ by Malcolm Tibbetts. There is also a significant amount of information available on the internet.

General Concepts

All segmented forms created in the program are refered to as vessels
A vessel is made up of stacked rings where each ring has a defined height and a repeating group of segments
All of the segments in the repeating group can be oriented horizontally or vertically which indicates the direction of the wood grain. Horizontal segments have a single miter angle while vertical segments have compound angles
Segments in the repeating group can be wedge shaped or block shaped. Wedge segments have a relative size and block type segments can have a relative size or an actual size
A segment can be a physical segment made of solid wood or multiple woods creating a pattern. A segment can also be defined as void leaving an opening in the ring
A vessel has a relative profile that adjusts proportionally as the vessel height changes
The actual dimensions of the segments on each ring are determined by the vessel profile and the number of times the repeating group of segments is applied to the ring
When a new vessel is created it can start out as a traditional vessel or a painted vessel
The traditional vessel provides the starting point for vessels that typically have a feature ring and generally have rings of many different heights. These vessels generally have a limited number of unique segments on a ring
A painted vessel generally has a large number of rings with the same height and each ring has a large number of segment and optionally open segments.
A painted ring is defined as a ring that was initially created as painted rings, has a horizontal orientation, all of the physical segments are wedge segments and have the same relative size and if the ring has open segments they all must be of the same type, have the same relative size and follow a pattern of alternating segments from physical to open
A block of painted ring is defined as a sequential group of painted rings that all have the same number of physical segments and all have the same number of repeating groups
A block of painted rings can be added to a vessel created as a traditional vessel
Non-painted rings can be added to a painted vessel but they cannot be made into a painted ring
Many operations can be performed over the entire vessel, a block of rings or a single ring

Known Issues

Ring calculations fail when creating rings with the number of repeating groups equal to 1 that contain one block or relative block and the block is the first or last segment in the group.
Ring calculations fail when creating rings with the number of repeating groups equal to 1 that contain two blocks or relative blocks and the blocks are positioned 180 degrees apart and they have different lengths.

Getting Started

Run the program and select the ‘App Defaults’ Button and define the parameters that will apply to the application as a whole. While some of these parameters can be changed at any time, others will only apply when creating a new vessel.

Next select [File][New] or [File][New Painted] from the main menu.

If you select [New] a dialog will allow you to specify the parameters of the initial vessel

Profile - The initial profile. After the vessel is created this can be changed at any time

Ring Height - The height of each ring created

Number of Rings - The number of rings in the vessel

Number of Repeating Groups - The number of times the specified segments are repeated on ring

Number of Segments - The number of segments in the number or repeating groups

Wood - The default wood

The values specified in this dialog for ring height, number of repeating groups, and number of segments are saved in the vessel parameters where they are used when inserting rings

If you select [New Painted] a dialog will allow you to specify the parameters of the initial vessel

Profile - The initial profile. After the vessel is created this can be changed at any time

Number of Rings - The number of painted rings in the vessel. Two additional rings are automatically included, one at the top and one at the bottom.

Number of Repeating Groups - The number of times the specified segments are repeated on the ring

Number of Segments - The number of physical segments in a repeating group

Ring Height - The height of each ring not counting the top and bottom rings

Open Segment CheckBox - If checked a void (open) segment will be added after each physical segment in the repeating group based on the relative ratio of the physical segment to the open segment. A 4:1 ratio indicates a physical segment arc length that is 4 times the arc length of the open segment. Another way to look at it is the physical segments are 80% and the open segments are 20% of the ring circumference

Open Segment Type - The open segment can be either a wedge or relative block shape

Wood - The default wood

The values specified in this dialog for ring heigt, number of repeating groups, and number of segments are saved in the vessel parameters where thay are used when inserting painted rings

The program does not impose any constraints on the approach used to make modifications. As changes are made the two side views display the current design. At any point during the design the current state can be saved to a file that can later be opened.

Application Defaults

The program saves the application defaults externally so any changes made will be retained when to program is closed. The following default will be immediately applied.

Field	Description
Length: Format	Controls the display format of length fields in the application (Decimal or Fractional). Note that length values can be always be input in either format.
Length: UOM	The units of measure specified applies to the entire application for both input and output of length values. If the Format is Decimal the available units are inches, centimeters and millimeters. If the Format is Fractional the units are inches
Length: Precision	Controls the display precision of length fields the application. If the Format is Decimal the available precision options are '0.0', '0.00', '0.000', and '0.0000'. If the Format is Fractional the precision options are '1/16', '1/32' and '1/64'. When values are displayed normal rounding rules are applied.
Angle (Deg.): Precision	Controls the display precision of angle fields in the application. The precision options are '0.0', '0.00', '0.000'. When values are displayed normal rounding rules are applied.
Vessel Folder	The default folder used for vessel files and plan output files
Pattern / Profile Folder	The default folder used for pattern and profile files

The following application defaults are used when creating a new vessel. The defaults are:

Field	Description
Work Area Height	The height of the display area in the profile view. This should be larger than the expected vessel height
Work Area Width	The width of the display area in the profile view. This should be larger than the expected vessel width
Saw Kerf	The saw kerf used when determining board length calculations
Offset	The offset from the vessel walls (both inside and outside) used when determining segment size.
Vessel Wall Thickness	The wall thickness of the finished vessel

Parameters

The vessel parameters are properties that apply to the current vessel.

Changes to the following fields apply to the current vessel. Changes to these values will be immediately applied to the current vessel.

Field	Description
Base Height	The height of the bottom of the inside of the vessel
Offset	The offset from the vessel walls (both inside and outside) used when determining segment size.
Wall Thickness	The wall thickness of the finished vessel
Work Area Height	The height of the display area in the profile view. This should be larger than the expected vessel height
Work Area Width	The width of the display area in the profile view. This should be larger than the expected vessel width

Changes to the following field apply to new ring only

Field	Description
Wood	The wood used for a new ring
Default Saw Kerf	The default saw kerf that applies to new rings. Once a ring has been created the ring saw kerf can be changed in the ring grid.

Profile

The profile view displays the outer profile along with the points that are used to create the profile. The display also includes the inner wall profile along with the offset curves that are used to determine the minimum outside radius and maximum inside radius for each ring. Both sides of the outer profile are displayed although the points, rings, inner wall profile and offset curves are only displayed on the right side.

The image is displayed on a grid that is based on the units of measure defined in the ‘App Defaults’. The vertical center line is displayed as a red line.

The height of the profile is determined by the stacked ring height. The profile shape is independent of height and will proportionally change as the height is increased or decreased by changing ring height or number of rings. Therefore increasing the height of the vessel increases the width.

The points are displayed as red circles and when the mouse is hovering over a point it turns green. When the point is green the point can be manipulated with the mouse.

The view can be zoomed in or out with the mouse wheel.

The points are stored as an ordered list and the user does not have the ability to change the order. When inserting a point the location in the list is based on the height of the new point. Using an ordered list of points allows the profile to rise above the vessel top. Unfortunately it also allows loops to be created in the profile that are not physically possible and causes calculation errors.

Modes

The Profile View has four modes that are selected on the view task bar and two icons for undo and redo options.

Pointer Mode

The pointer mode allows the modification of the profile curve. Point positions can be changed or points added or deleted.

Moving a Point

When hovering over a point the point will turn green and can be moved by holding the left mouse button down and dragging the point to a new location. As the point is being moved the shape will continually be evaluated and displayed. After a point is repositioned the inner wall profile and minimum ring profile is displayed.

Adding a Point

A new point can be added by positioning the mouse on the right side of the vessel and pressing the control key and left mouse button. The point will be inserted at the specified height. If the point is inserted at a location that is higher than the vessel height it will be inserted before the top point. Once the point is added the point can then be moved.

Removing a Point

When hovering over a green point and pressing the control key and left mouse button the point is removed and the resulting profile is reevaluated and displayed.

Horizontal Scale Mode

The horizontal scale mode allows the movement of all points to the right or left. Selecting the horizontal mode draws a box around the right side of the profile with a rectangular handle in the middle of the right side. Position the cursor over the handle and hold the left mouse button down to scale the profile as the mouse moves.

Pan Mode

The pan mode allows the viewable area of the Profile View to be repositioned by holding the left mouse button down and moving the mouse.

Measure Mode

The measure mode provides a measurement between two locations by selecting an initial location by depressing the left mouse button and then dragging the mouse with the left mouse button down. A line is drawn with the current distance displayed.

Undo

You can undo changes to the profile points while the view is active. The icon becomes enabled when there are changes to undo.

Redo

If previous changes have been undone they can be redone unless a manual change has been made. This icon becomes enabled when there are entries in the list that have been undone.

Ring List View

The ring list view contains a top grid that contains the attributes of each ring and a bottom grid that displays the details of the repeating group of segments for the selected ring. Once a row is selected the attributes can be changed directly or row operations relative to the selected row can be performed through the buttons or the context menu.

Changes to the attributes on a row in either grid will not take effect until a new row is selected. You can also cancel the current changes on a row with the Esc key.

Ring Grid

The ring grid contains a row for each ring with the top vessel ring at the top of the grid. Note that the ring numbers start at the bottom of the vessel with the bottom ring being ring 1.

When a row is selected in the grid the corresponding ring will be highlighted in the Profile view in the lower right viewport.

Repeating Group Grid

The repeating group contains a row for each segment in the group. The order of the segments determines the order in which they will appear in views that display the rings

The segments that make up the repeating group can be either wedge or block segments with at least one segment being a wedge. For any given ring there is a limit to the total outside lengths of the block segments. as the block lengths increase the inner length of the wedge segments decreases until it becomes zero and further increases in the block lengths results in an incorrect calculation and the segment will not display in the 3D view.

Segment Pattern Editor

The segment pattern editor allows you to specify the design of a multi-wood segment. The pattern is defined by adding shapes to the segment and then modifying them to achieve the desired pattern. Each shape has a specified wood and z-order. New shapes will be drawn on top of existing shapes although the order can be changed later.

The pattern editor displays the segment outer surface as it would be constructed (this is not the turned surface). If the segment is a wedge and the pattern cut is 'Straight' it is important to note that during turning a portion of the left and right side of the wedge will be removed.

Patterns can be built up by overlaying a new shape over a part of an existing shape. In these cases only the visible parts of the shapes will be displayed on the vessel.

The shapes in the pattern editor can extend beyond the boundaries of the segment. In many cases this allows a pattern to be created in a simpler way. When the final image is being displayed these areas are ignored.

Right Triangle		Select the right triangle shape to draw a right triangle positioning the mouse cursor at one end of the hypotenuse, holding the left mouse button down and dragging the mouse to the other end of the hypotenuse and then releasing the mouse button

Tools

The tools are used to modify pattern shapes, provide information or modify the view.

In general the left mouse button is used for selection by clicking or by creating a rectangular area enclosing shapes. Selecting shapes usually deselects current selections unless the 'Ctrl' key is pressed during the operation

Holding the left mouse button down while moving the mouse is used to move selected shapes, move handles and creating a rectangular area

Tool	Image	Description
Selector		The selector tool allows the selection of one or more shapes. The selector tool does not allow shapes to be moved or modified. Note that the context menu allows all shapes to be selected, unselected or deleted or selected shapes to be deleted, moved to the front or back of other shapes, copy and paste, horizontal mirror copy and vertical mirror copy. Selecting shapes with the left mouse button click Clicking the left mouse button at a position will select any shapes at that position and unselect other shapes that do not share the mouse position. If the Ctrl key is held down when clicking at a position shapes that are currently selected will remain selected Selecting shapes within a bounding rectangle Shapes can also be selected by enclosing then in a bounding rectangular area defined by holding the left mouse down and dragging the mouse. Note that the shape must be entirely contained within the rectanglar area to be included. If the Ctrl key is help down at the same time other currently selected shapes will remain selected.
Move		The move tool allows the user to select shapes, move selected shapes or change a shape by moving individual points. Selected shapes can be moved with either the left mouse button pressed or with the Up, Down, Left or Right keys. Individual points can only be moved with the left mouse button pressed. Selecting a single shape Position the cursor over a shape and use the left mouse button to click on the shape. The selected shape will be displayed with a blue border with small rectangle handles at select points on the shape. Note that the circle and pie shapes do not display handles. Selecting shapes with a bounding rectangle Position the cursor outside of any shapes, press the left mouse button down and draw the mouse to create a bounding rectangle. All shapes completely contained within bounding rectangle will be selected. This will also include shapes that may be hidden beneath other shapes. The selected shapes will be displayed with a blue border. Moving a single selected shape To move the shape, position the cursor within the shape, press the left mouse down, the cursor will change and then drag the shape to the new position. Moving a single selected shape handle To move the shape handle, position the cursor over the handle. The cursor will change indicating the handle is being selected. Press the left mouse down and drag the handle to a new position. The underlying shape point will move creating a modified shape. Moving multiple selected shapes To move multiple selected shapes, position the cursor within one of the shapes. Press the left mouse button down, The cursor will change and drag the selected shapes to a new position. Exceptions Circle shape The circle is made up of a large number of points and when selected does not display handles. If the cursor is positioned on the circumfrence and the cursor changes indicating you are over a point the point can be moved with the left mouse button pressed down. Pie shape The pie is made up of a center point and an arc with a large number of points and when selected does not display handles. If the cursor is positioned on the center point or the arc and the cursor changes indicating you are over a point the point can be moved with the left mouse button pressed down. Line Shape The line is a special case. The move tool cannot change the direction of the line but it can change the width, length and end shape. The line is initially drawn with rectangular ends. When selected the line has eight handles, two on the length midpoints that are used to change the width and three on each end, two on the corners and one in the middle. End Handles - By default the center end handle is used to change the length of the line and the corner handles are used to change the angle of the end. The opposite corner remains stationary and the center handle moves to keep the end linear. If the Ctrl key is pressed the end handles move independently of each other. If the Shift key is pressed when moving one of the corner handles the center handle remains stationary and the other corner handle moves in the opposite directions. Width Handles - By default moving a width handle moves the line edge along with the center end handles to increase or decrease the width. If the Ctrl key is pressed both edges move relative to the center axis of the line.
Scale		The scale tool allows the user to select one or more shapes and scale them as a group. The selected shapes have a rectangle box drawn around them with 8 scaling handles, 4 corner handles and 4 side handles. By default moving a corner handle scales the shapes along the diagonal with the opposite corner stationary. Moving a side handle scales the shapes by keeping the opposite side stationary If the 'Ctrl' key is held down when a scaling handle is moved the center of the rectangular box remains fixed If the 'Shift' key is held down when a corner scaling handle is moved the opposite corner remains stationary but the handle can be moved in any direction
Pan		The pan tool allows the user to reposition the view. This is useful when zooming in to specific areas of the display
Rotate		The rotate tool allows the user to rotate the selected shapes around a specified point. The first step is to define the pivot point by positioning the mouse pointer and clicking the left mouse button. Next move the mouse to another position and again click the left mouse button to define the reference line. Now as you move the mouse the angle will be displayed and the selected shapes will be rotated around the pivot point. Once the shapes are at the desired position click the left mouse button to end the operation.
Measure		The measure tool allow the user to determine the distance between two points on the display. Position the mouse pointer to the starting location and then hold the left mouse button down while moving the mouse to the ending location. As the the mouse is being moved a line is drawn with the current distance. Once the left mouse button is released the line is removed
Undo		Undo the last operation in the operation chain
Redo		Redo the last operation undone in the operation chain

Parameters

Parameters	Description
Current Wood	The wood that is used when creating a shape
Background	The background wood of the segment
Snap Grid	Checking the snap grid checkbox causes the point being moved to be snaped to the closest intersection of the grid lines. This applies to all shapes except the line shape.
Grid Type	Determines how the grid is drawn. Actual The grid is based on vertical and horizontal increment values and the units of measure. As an example if the units of measure is inches and the horizontal increments is 8 the vertical lines are spaced 1/8 inch apart. Relative The grid is drawn relative to the size of the segment. As an example if the horizontal increments is 5 then the vertical grid lines divide the segment width into 5 equal width sections. When a pattern is first added to a segment the default grid type is 'Actual'. The grid type is stored with the pattern and will be set to the stored value when the pattern is reopened.
Vertical Increments	The number of vertical increments. How the grid is drawn depends on the grid type. If the grid type is Actual the horizontal grid lines partition the current unit of measure. For inches if the value is 8 each inch is divided into 1/8 inch increments. If the grid type is Relative the horizontal grid lines partition the segment height into the number of vertical increments. When a pattern is first added the value is set based on the units of measure. For inches the default value is 8, for centimeters the default is 10 and for millimeters the default is 1. The vertical increments value is stored with the pattern and will be set to the stored value when the pattern is reopened
Horizontal Increments	The number of horizontal increments. How the grid is drawn depends on the grid type. If the grid type is Actual the vertical grid lines partition the current unit of measure. For inches if the value is 8 each inch is divided into 1/8 inch increments. If the grid type is Relative the vertical grid lines partition the segment width into the number of horizontal increments. When a pattern is first added the value is set based on the units of measure. For inches the default value is 8, for centimeters the default is 10 and for millimeters the default is 1. The horizontal increments value is stored with the pattern and will be set to the stored value when the pattern is reopened
Dimension Type	Determines how the pattern changes if the segment size changes. Actual The size of the pattern shapes remains fixed regardless of changes in the segment dimensions. Relative TThe pattern remains in the same proportions relative to the segment dimensions. As an example if the segment width changes the pattern width changes. When a pattern is first added to a segment the default dimension type is 'Relative'. The dimension type is stored with the pattern and will be set to the stored value when the pattern is reopened.
Tool Properties	Displays the current tool and optional properties
Cursor Position	Displays the current cursor position as a decimal with three decimal places. Note that the zero position is at the center of the pattern.
