Creating a Free Polygon

Create a free polygon shape by defining first and subsequent points.

\newp

Define the first and subsequent points. A guideline is stretched between the previous point and the current location of the cursor.

You can start a polygon by an arc, if you wish.

Only a single polygon can be current at a given time. As soon as you call this command the "current polygon" status is initialized.

Polygons may be open or closed loops. Close the polygon (connect the current point to the first point) by pressing Enter during its creation, or by using the Close polygon (\endp) command on a "current polygon".

When closing the polygon, you have the possibility to chose the type of 2D polygon or to continue to expand it to 3D as a prism.

In surfaces viewing mode the surface is displayed in the same color as the polygon contour. If it is changed to a symbol polygon (polyline), it appears as a transparent outline.
