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.

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.

Tabbed Windows

The default tab behavior of macOS is to open new tabs only when you are in a full-screened application. Rhino respects your macOS System Preferences.

To turn on tabs all the time, in macOS, navigate to Mac System Preferences > Dock > Prefer tabs when opening documents and set it to Always.

Merge windows for each model

Each model will have a separate window and tabs for sub-windows like Materials and Layouts.

Merge windows by function

Model windows are merged with model windows, material windows are merged with material windows, and layout windows are merged with layout windows.

For example, if you had three models open each with their materials and layouts windows open, you would get three windows with three tabs each (one window with three model tabs, one window with three material tabs, one window with three layout tabs).

Merge all windows into one window

All Rhinoceros windows are merged into one window with separate tabs.

For example, if you had three models open each with their materials and layouts windows open, you'd end up with nine tabs.

CreaseSplitting

Toolbar Menu

Not on toolbars.

Not on menus.

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.

Toggle

SplitAlongCreases

Determines whether the result will be a polysurface with edges at creases or a single surface with creases where the input curves had kinks.

Commands affected

UseExtrusions

Toolbar Menu

Not on toolbars.

Not on menus.

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

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.

 Extrusions enabled

These commands can make use of lightweight extrusions:

ConvertExtrusion

The ConvertExtrusion command converts extrusion objects to surfaces and polysurfaces.
