Use model.component(<ctag>).geom(<tag>).create(<ftag>,operationName) to combine geometric objects in different ways.

Use model.component(<ctag>).geom(<tag>).feature(<ftag>).selection(property) to select the objects to combine. The default selection is empty.

dom

Show selections, if selresult is on, in physics, materials, and so on; in part instances; or in 3D from a plane geometry. obj is not available in a component’s geometry. dom, bnd, and edg are not available in all features.

•

For Compose, the input objects are combined using the set formula in the property formula. The operators +, *, and - correspond to the set operations union, intersection, and difference, respectively. The precedence of the operators + and - are the same. * has higher precedence.

•

For Intersection, the objects in input are intersected.

•

For Difference, the objects in input2 are subtracted from the union of the objects in input to form a set difference.
