Selecting a polygon mesh provides specialized PEDIT options.
The following prompts are displayed.
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.
Mclose and Nclose are replaced by Mopen and Nopen if the polygon mesh is currently closed in the M or N 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.
