CSGBuilder

Creates Constructive Solid Geometry (CSG) from pairs of solid geometry features which are input through the A and B ports.

CSG is useful for representing complex solids by specifying the Boolean operations between simpler solids. For example, a wall with a window can be represented by taking the difference of the solid wall against the window. The CSGBuilder can be used to create a CSG solid that is comprised of relationships (order of Boolean operations or a hierarchy of Boolean operations) between the simpler solids.

Input Ports

  • A and B: Pairs of solid geometry features.

Output Ports

Each Boolean operator is output via its corresponding port:

Parameters

Related Transformers

CSG is the unevaluated model. The CSGEvaluator can be used to compute the equivalent boundary representation of the CSG solid.  

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter.
