Compound Shapes

Compounds group several OCCT shapes into one object in Bitbybit without fusing them together. That distinction matters: a boolean union merges overlapping solids into a single body, while a compound keeps each part separate and individually addressable, which is what you want for a multi-part assembly, a set of laser-cut pieces laid out on a sheet, or any result you will later colour or export part by part. These pages cover creating compounds, drawing them, taking them apart again to get at the shapes inside, and when a compound is the right choice over a union.
