6.3. Draw regular shapes

6.3.1. Draw a wheel

A wheel is a regular shape defined by its center, its radius, and a number of vertices and other parameters. It is drawn as a path element with multiple outlines. The shape is calculated by a constraint.

See draw wheel showcase for an interactive demonstration.

Click on the wheel icon in the Shapes menu and Regular section:
Click the center and radius points
Then set the wheel parameters:
Figure 6.7. Wheel parameters
- Vertices count
  - Click on the count, buttons +/-, or enter the value
- Orientation angle
  - Check clockwise
  - Set the angle as a ratio to the central angle using the cursor or field
  - Or set the angle as degrees using the cursor or field
- Hub
  - Select wheel without hub option
  - Or set the hub radius as a ratio to the wheel radius using the cursor or field
- Shape constraint
  - Keep
    The element's geometry is locked (modification of points or segments is impossible)
  - Remove
    The geometry of the element becomes modifiable like any path element by default. The shape is no longer identifiable as a wheel.
Set the stroke and fill style of the shape

Select the shape
Click on the Shape settings icon

The shape is drawn by a single path element with multiple outlines.

To assign a different style to each outline, it is necessary to remove the constraint and then split the path, resulting in one path element per outline:

Select the shape
Click on the Shape settings icon
Select Remove Shape constraint and click Apply button
Click Split path icon (expert profile)
Apply Split path action
Select each outline to set its fill style

6.3.2. Draw a polyhedron

A polyhedron is a regular shape defined by its center, its radius, and a number of vertices and other parameters. It is drawn as a path element with multiple outlines. The shape is calculated by a constraint.

See draw polyhedron showcase for an interactive demonstration.

Click on the polyhedron icon in the Shapes menu and Regular section:
Click the center and radius points
Then set the polyhedron parameters:
Figure 6.8. Polyhedron parameters
- Vertices count
  - Click on the count, buttons +/-, or enter the value
- Orientation angle
  - Check clockwise
  - Set the angle as a ratio to the central angle using the cursor or field
  - Or set the angle as degrees using the cursor or field
- Lines
  - Select outline
  - Or slices
- Shape constraint
  - Keep
    The element's geometry is locked (modification of points or segments is impossible)
  - Remove
    The geometry of the element becomes modifiable like any path element by default. The shape is no longer identifiable as a wheel.

6.3.3. Draw a star

A star is a regular shape defined by its center, its radius, and a number of vertices and other parameters. It is drawn as a path element with multiple outlines. The shape is calculated by a constraint.

See draw star showcase for an interactive demonstration.

Click on the star icon in the Shapes menu and Regular section:
Click the center and radius points
Then set the star parameters:

- Vertices count
  - Click on the count, buttons +/-, or enter the value
- Orientation angle
  - Check clockwise
  - Set the angle as a ratio to the central angle using the cursor or field
  - Or set the angle as degrees using the cursor or field
- Arrows, select the draw arrows mode
  - Select connect vertices and set the number of vertices between connected arrows
  - Or set the inner radius as a percentage
- Lines, select the draw lines mode
  - Outline (only one contour)
  - Petals (one contour for each vertex)
  - Half petals (two contours for each vertex)
- Shape constraint
  - Keep
    The element's geometry is locked (modification of points or segments is impossible)
  - Remove
    The geometry of the element becomes modifiable like any path element by default. The shape is no longer identifiable as a regular star.
