Surface File Plot

This tool plots a Grid or TIN file in the current drawing as points, lines, 3DFaces or a mesh. If multiple object results (such as points, lines, faces) it can bind these together in an CAD group making it easier to select later.

Keyboard Command: SurPltAll

Procedure:

1. Open the drawing to place the surface in.
2. Optionally establish a new layer and make it current.
3. Initialize the tool.
4. Choose the Load button to select a grid file.
5. Designate desired output options.
6. Choose the OK button to generate the results.

General Notes:

• Large surfaces may take time to process.
• Turning on the Group Results toggle on large files is not recommended.
• To plot the full elevation range, leave the Min/Max Elevation fields blank.
• Because this tool can be processor intensive, you may want to turn on the System Events toggle so the CAD engine can repaint windows, etc.

Mesh Notes:

• Subdivision Meshes are not available on AutoCAD 2007-2009.
• AutoCAD limits a Polymesh to roughly 32,767 vertices, so large grids may exceed this and this option will be grayed out.
• When the Polymesh option is taken, the Group Results option does not apply (its a single object) and will be ignored.
