Drawing polygons

Polygons are closed polylines comprised of a minimum of three and a maximum of 1,024 equal-length sides.

You can draw polygons using the following methods:

  • Center - Vertex: first define the center point, then the vertex (= radius of the circumscribed circle method).
  • Center - Side: first define the center point, then the midpoint of a side (= radius of the inscribed circle method).
  • Edge: define the length of the side of the polygon.

The Polygon tool is available on:

  • the Draw menu
  • the Draw toolbar
  • the Draw ribbon panel
  • the Draw tab of the No Selection Quad

General procedure

  1. Launch the POLYGON command.

    Prompts you: Polygon: Set number of sides or [Width of line/Multiple polygons] <4>:

  2. Do one of the following:
    • Press Enter or right click to accept the current number of sides.
    • Type a value, then press Enter.

    Prompts you: Specify by: Set center of polygon or [specify by Edge]:

  3. Specify a point.

    Prompts you: Specify by: Select midpoint of side or [specify by Vertex]:

  4. Specify a point.
Note:
  • The option that you choose in step 3 (midpoint of side or specify by Vertex) is remembered the next time.
  • The number of sides is set by the POLYSIDES system variable, but the value is not saved between sessions. The first time you launch the POLYGON command in a BricsCAD session POLYSIDES = 4.
