trim operation

Syntax

• trim()

Description

The trim operation applies the current shape's trim planes to the geometry of the current shape. Trim planes are generated by a component split and can be enabled and disabled by the trim attribute. Trimming is automatically performed when a primitive or an asset is inserted in the scope. Use the geometry.isInstanced function to check if an inserted asset was trimmed.

Examples

Manual trimming

A roof face is extruded and trimmed by both vertical and horizontal trim planes. The trim planes are generated by the component split. Setting trim.horizontal to true activates horizontal trimming. Roof--> roofHip(45) comp(f) { 1 : Face } Face--> s('2,'2,0.5) center(x) extrude(0.5) set(trim.horizontal, true) trim()

Automatic trimming

A cube is inserted in the scope of a roof face. The insert and primitive operations automatically trim the geometry. Horizontal trim planes are not enabled by default. Face--> s('2,'2,0.5) center(x) primitiveCube()
