The 3D Polygon tool creates polygons that have a location in 3D space, but no height. The polygon can be created through any 3D point, not necessarily constrained to the working plane.
To create a planar 3D polygon:
1. Click the 3D Polygon tool from the 3D Modeling tool set.
2. Click to set the polygon’s start point (first vertex).
3. Click at each vertex.
4. Double-click at the final vertex to end an open polygon; click at the starting vertex (a point cue displays) to end a closed polygon (the first and last vertex are automatically joined).
