Simplifying 3D Polygons

If the existing site model was created from 3D polygons (not 3D loci or stakes), you can reduce processing time by removing redundant polygon vertices within a specified tolerance. For example, this removes extra vertices in straight or nearly-straight segments of imported 3D polygons used as source data. This feature does not significantly change the appearance of the site model, but it can dramatically decrease the time it takes to process the model.

The Simplify 3D Polygons command available in Vectorworks Architect and Landmark is specialized for certain site model workflows. To simplify 2D polygons, 3D polygons, and polylines in other workflows, see Simplifying Polygons and Polylines.

To remove redundant 3D polygon vertices:

1. Select the 3D polygon(s). (The original polygons remain unchanged.)

2. Select the Simplify 3D Polygons command from the appropriate menu:

●    Architect workspace: AEC > Terrain > Simplify 3D Polygons 

●    Landmark workspace: Landmark > Simplify 3D Polygons

The Simplify Selected 3D Polygons dialog box opens.

3. Enter a Simplification Tolerance value, and select a layer from the Put Simplified Result in Layer list.

4. Click OK.

Redundant vertices are removed from the 3D polygon(s) and the results are sent to the layer specified.
