Polygon

General

• You can sketch a polygon by clicking the location of the center point and one corner point.
• You can sketch the polygon freely, or you can define the size of the polygon based on the size of the circle that fits inside (=width across the flat) or the size of the circle passing through the corners of the polygon.
• You can orient the first side of the polygon horizontally or vertically, or parallel to the reference line or perpendicular to the reference line.
• You can enter the number of sides and, if necessary, the length of the side or the diameter of the circle.
• You can choose whether to draw an auxiliary circle in addition to the polygon.
• You can choose whether to add the necessary constraints (angle, coincidence, tangential, equal distance and diameter constraints) automatically or not.

Sketch a polygon

1. Select the function Sketch | Lines | N-gon or
   • select the context-sensitive function Line > N-gon.
   • The program opens the dialog box N-gon.

     

2. In the dialog box, select the drawing method
   • Free draw: You can click the size of the polygon.
   • Inner diameter: You can enter the size of the circle that fits inside the polygon, i.e. the width across the flat.
   • Outer diameter: You can enter the size of a circle drawn around a polygon.
3. Enter the number of sides
4. Enter either the length of the side or the diameter of the circle.
   • These are available if you selected an Inner diameter or Outer diameter as the drawing method.
   • The program calculates one of the values.
5. If necessary, select
   • Automatic constraints if you want the program to add the necessary constraints.
   • Draw help circle if you want the program to draw an auxiliary circle inside or outside the polygon.
6. If necessary, select the line properties, under Sketch | Style
7. Select the center point of the polygon.
8. Select the corner point of the polygon.
   • Before clicking the corner point, you can orient the polygon horizontally or vertically by clicking the cursor when the X locking appears on the cursor.

     

9. Repeat steps 6 to 8 to continue sketching polygons of the same size.
   • If you want to sketch other types of polygons, stop sketching polygons and start over.
10. Stop sketching polygons
    • Select another function or
    • Press the middle mouse button or
    • Press the Esc key or
    • Press the V key (V = Confirm).
