Filtering 3D Polygons

If the existing site model is created from 3D polygons (not 3D loci), processing time can be decreased 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 can dramatically decrease the time it takes to process the model.

To filter redundant 3D polygon vertices:

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

2.	Select Landmark > Filter 3D Polygons (Landmark workspace) or AEC > Terrain > Filter 3D Polygons (Architect workspace).

The Filter Selected 3D Polygons dialog box opens.

 

Parameter	Description
Filter Deviation Distance	Specifies the tolerance for removing unnecessary vertices
Put Filter Results on Layer	Select the layer where the filtered polygons will be placed

3.

Click OK.

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