3D Polygon Mesh Selection (PEDIT)

Quick Reference

If you select a polygon mesh, the following prompt is displayed:

List of Prompts

The following prompts are displayed.

Enter an option [Edit vertex/Smooth surface/Desmooth/Mclose/Nclose/Undo]: Enter an option or press Enter to end the command

Mclose and Nclose are replaced by Mopen and Nopen if the polygon mesh is currently closed in the M or N direction.

Edit Vertex

Edits individual vertices of a polygon mesh that can be seen as a rectangular M by N array, where M and N are the dimensions specified in 3DMESH. The SURFTAB1 and SURFTAB2 system variables store M and N values for RULESURF, TABSURF, REVSURF, and EDGESURF.

Pressing Enter accepts the current default, which is either Next or Previous.

Next: Moves the X marker to the next vertex. The marker does not wrap around from the end to the start of the mesh, even if the mesh is closed.
Previous: Moves the X marker to the previous vertex. The marker does not wrap around from the start to the end of the mesh, even if the mesh is closed.
Left: Moves the X marker to the previous vertex in the N direction. The marker does not wrap around from the start to the end of the mesh, even if the mesh is closed.
Right: Moves the X marker to the next vertex in the N direction. The marker does not wrap around from the end to the start of the mesh, even if the mesh is closed.
Up: Moves the X marker to the next vertex in the M direction. The marker does not wrap around from the end to the start of the mesh, even if the mesh is closed.
Down: Moves the X marker to the previous vertex in the M direction. The marker does not wrap around from the start to the end of the mesh, even if the mesh is closed.
Move: Repositions the vertex and moves the editing mark.
Regen: Regenerates the polygon mesh.
Exit: Exits Edit Vertex mode.

Smooth Surface

Fits a smooth surface. The SURFTYPE system variable controls the type of surface this option fits. The types of surfaces include quadratic B-spline, cubic B-spline, and Bezier.

Desmooth

Restores the original control-point polygon mesh.

Mclose

Closes the M-direction polylines if the polygon mesh is open in the M direction.

Mopen

Opens the M-direction polylines if the polygon mesh is closed in the M direction.

Nclose

Closes the N-direction polylines if the polygon mesh is open in the N direction.

Nopen

Opens the N-direction polylines if the polygon mesh is closed in the N direction.

Undo

Reverses operations as far back as the beginning of the PEDIT session.
