The Quick Ground Extraction tool extracts terrain in a Scalable mesh (3SM) from a user defined area.

Access the tool:

• Reality Modeling workflow: Extract tab > Scalable Mesh
• Open Reality Mesh Attachments dialog then select Tools.

The Quick Ground Extraction tool extracts ground in a user defined area. The user can draw a Block, a Shape or select a closed element to define the area. The points that define the area should be snapped on the ground.

The tool extracts the ground inside the defined area and outputs it in a new 3SM attachment that is created in a new folder located in the same folder as the DGN file.

Then both 3SM attachments are clipped for seamless display. The original 3SM is clipped using a Clip Mask and the new 3SM is clipped using a Clip boundary.
