Spline Mask
The spline mask corresponds to a Boolean object for splines. You can use it to cut out and join spline shapes, etc. This works best if the splines are flat and lie in the same plane.
A very nice tool for quickly creating new spline shapes. You can place the spline mask object wherever you would place a normal spline, for example:
- Extrude object
- Sweep object etc.
In addition, any (closed) spline shape can be displayed polygonally.
A spline mask can be converted into a spline or a polygon object (if Create Caps is activated) using the Make Editable or Current State to Object command.
More than 2 splines can be assigned to a spline mask. The target spline is always the first one under the spline mask object:
The first sub-object of the spline mask is always the target spline (here Mode A minus B). All other splines are cut out of the target spline here.
In some modes - such as the subtraction modes - the target spline is important, in others (e.g. Union) it is not, where the order of the subordinate splines does not matter.
Example
In the following scene, a few simple basic spline objects are combined using the spline mask.
