Overview

SegTurn is a Microsoft Windows program that makes it easy to design segmented bowls and vessels. You start with a simple default design and continually make changes until you are satisfied with the design or you can start with a painted segment vessel where you define the initial parameters. In either case 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 default vessel is a good starting point for traditional designs that have a small number segments in the rings and many of the segments are similar and the vessel typically has a feature ring

The painted vessel is targeted for vessels with 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 vessel 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 wooden bowls and 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.

Features

  • Provides the option of starting with either a default vessel or a painted segment vessel
  • Vessels can have closed segment rings or rings with open segments
  • The vessel profile is based on a Bezier curve defined by user specified points
  • A number of standard vessel profiles are available
  • Rings and segments are displayed and manipulated in master / detail style grids
  • Over 50 wood species to choose from
  • A pattern editor for designing a segment with multiple woods and shapes
  • A painted pattern editor to design a pattern that is applied to the entire vessel
  • Options to change attributes over the entire vessel at once
  • A 2D graphical display of each ring from a top view perspective
  • Display of the ring stack prior to turning in a 3D view
  • Display of the finished turned shape in a 3D view
  • Multiple ways to output relevant specifications for construction of the vessel
  • Saving the design to a serialized file
  • Opening a saved design file
  • Saving a segment pattern to a file so it can be applied to a different segment
  • Saving a vessel profile to a file so it can be applied to a different vessel
  • Ability to change any aspect of the design and immediately see the impact on the final product
  • Application defaults automatically saved externally and retrieved when the program is started
  • Vessel defaults applied when adding new rings
  • Each vessel can have an offset and wall thickness specified

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 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 default vessel or a painted vessel
  • The default 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 from a default vessel
  • Non-painted rings can be added to a painted vessel but they cannot be made into a painted ring

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 Default] or [File][New Painted] from the main menu.

If you select [New Default] a default vessel design will be created as a starting point. The design can then be modified through the Profile and Ring List views.

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

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 vessel.

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


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.

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

The saw kerf used when determining board length calculations

Changes to the following field does not update the existing ring values.

Field

Description

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.

Segment Pattern Editor

The segment pattern editor allows you to specify the design of a multi-wood segment. The pattern is defined by adding shape objects 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.

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.

Tools

The tools are used to modify the pattern objects, 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

Pointer to select graphic objects. Clicking the left mouse button at a position will select any objects at that position and deselect other objects that do not share the mouse position. If the Ctrl key is held down when clicking at a position objects that are currently selected will not be deselected

Objects can also be selected by enclosing then in a rectangular area defined by holding the left mouse down and dragging the mouse. Note that the object 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 objects will not be deselected

Move

The move tool allows the user to select shapes, move selected shapes or change a shape by moving individual points. Objects 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.

Objects can be selected in a similar way as with the 'Selector' tool except that only the top shape at a position will be selected.

When a single shape is selected all shape types except for the circle and pie will display handles that can be used to move the corresponding point. The circle and pie are made up of a large number of points and a point on the circumference can be moved without a handle.

The line is a special case. The move tool cannot change the direction or width of the line but it can change the length and end shape. The line is initiall drawn with rectangular ends. When selected each end has three handles, two on the corners and one in the middle. By default the center handle is used to change the length of the line and the corner handle is used to change the angle of the end (the opposite corners remains stationary). If the Ctrl key is pressed the end handles move independently of each other. If the Shift key is pressed the center handles remains stationary and the corner handles move in opposite directions.

Scale

The scale tool allows the user to select one of 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 objects 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 the angle will be displayed and the 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

Painted Pattern Editor

The painted pattern editor allows you to specify a pattern over the entire vessel by specifying the wood for each segment. The editor displays the repeating group of segments for each ring in the entire vessel and also displays the current wood. When creating a pattern over the entire vessel it is sensitive to changes in ring angle offsets so care should be taken when adding rings.

Print Ring Report

This output provides information about each ring and the segments that make up the ring. For standard rings information about each segment is provided. For painted rings only information about one segment and optionally an open segment is provided since all segments have the same physical dimensions. For painted rings a list of the segment number and wood type is also included

This report can be used for any type of vessel

Print Ring Image Report

This output provides a page for each ring with general information and a graphical top view of each ring with the segments colored by wood type and the associated segment number. Also included is a listing of each wood type and the segment numbers

This report can be used for any vessel type but it was mainly designed for painted vessels

Output All Fields CSV

This output provides a comma separated values file of all fields describing the vessel with a row for each segment.
