The General options control menu functions, undo, and start-up commands.
Command Lists
Run these commands every time a model is opened
Defines a list of commands that will run automatically whenever you open a model.
Never repeat these commands
Defines a list of commands that will not repeat when you press Enter.
Only command names can be flagged as do-not-repeat. If a command is in a macro, it will repeat even if it is on this list.
Using wild cards
You can use a question mark (?) for any letter, and an asterisk (*) for any string. For example:
Sel* will not repeat all commands that start with "Sel".
Mesh????? will not repeat MeshPatch, MeshPlane, MeshSplit, etc.
Default surface isocurve density
Show surface isocurves
Sets the display of surface isoparametric curves for new objects.
Isocurve density
Defines the default surface isoparametric curves density for new objects.
| Value | Isocurve density |
|---|---|
|
0 |
No isocurves on knot-free spans. |
|
1 |
One isocurve at each knot, or one isocurve on knot-free spans. |
|
2 |
One isocurve at each knot, plus one isocurve between knot locations. |
|
3 |
One isocurve at each knot, plus two isocurves between knot locations. |

When curves have kinks, surfaces made with those curves as input can have creases. The CreaseSplitting command controls whether commands that make surfaces from kinked curves divide resulting surfaces into polysurfaces with edges at the creases or into single surfaces with creases.
When the input curve has a kink, the resulting surface will have a crease.
CreaseSplitting=Enabled (left); CreaseSplitting=Disabled (right).
Loft results with control points on. The object at the left is a polysurface; turning on control points is not allowed.
| Command-line options | |
|---|---|
|
Enable |
The result will be a polysurface with edges at creases or a single surface with creases where the input curves had kinks. |
|
Disable |
The result will be a single surface with creases. |

The UseExtrusions command controls whether extrusion objects or polysurfaces are created by commands like Box, Cylinder, ExtrudeCrv, Pipe, and Slab that create straight-sided objects.
Extrusion objects are defined by a profile curve and a straight line. They use less memory and mesh faster. They are a good option when making models containing lots of simple shapes.
Polysurface (left) vs. extrusion object (right).
Steps
- Specify the planar extrusion output object type you want to use.
A report on the internal data structure of the object displays.
Command-line options
Extrusion
Commands uses light-weight extrusion object when possible.
Polysurface
Commands always create polysurfaces.
Commands with extrusions enabled
Commands with the button below near the top of the topic can use extrusions.
These commands can make use of lightweight extrusions:
