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()
    		Manual trimming

    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()
    		Automatic trimming
