The General options control menu functions, undo, and start-up commands.
General
When you right-click in the command area, or program your middle mouse button to display the recently-used commands menu, a menu displays at the cursor location containing a list of recently-used commands and the commands you have Entered as your favorites.
This allows you to choose the maximum number of items that can appear in the most-recently-used command lists.
Your favorite commands will always display in the pop-up menu at the top of the pop-up menu above the most-recently-used commands.
Defines a list of commands that will run automatically whenever you start Rhino.
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.
The maximum amount of memory Rhino will attempt to use.
Show surface isocurvesSets the display of surface isoparametric curves for new objects.
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.
| 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. |

UntrimHoles
Untrims selected holes (interior trims) that do not touch surface borders.
ExtendSrf
Lengthen a surface by a value.
Loft
Fit a surface through profile curves that define the surface shape.
MatchSrf
Adjust a surface edge to have continuity with another surface edge.
RailRevolve
Revolve a profile curve around an axis and along a rail curve.
Revolve
Create a surface by revolving a profile curve around an axis.
Sweep1
Fit a surface through profile curves and one edge curve.
Sweep2
Fit a surface through profile curves and two edge curves.
Untrim
Remove trim curves from trimmed surfaces.
UntrimAll
Untrims interior (holes) and exterior trims on the selected surfaces all at once.

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.
Command-line options
Commands uses light-weight extrusion object when possible.
Use extrusions when possible is enabled in Options > General.
Commands always create polysurfaces.
Use extrusions when possible is disabled in Options > General.
Commands with the button below near the top of the topic can use extrusions.
These commands can make use of lightweight extrusions:
