SurfaceBuilder

Cuts holes in surface features with other surface features. A surface that is cut by another surface must be co-planar with that second surface, and contain that second surface.

All surfaces are converted into faces (for example, a mesh is converted into faces – one face per mesh part).

Parameters

Note: Attribute lists are not accessible from the output schema in Workbench unless they are first processed using a transformer that operates on them, such as ListExploder or ListConcatenator. All attribute list transformers are displayed in the Contents pane of the Transformer Help under Lists. Alternatively, AttributeExposer can be used.

Example

The example below illustrates the input features on the left and the output features on the right. The input consists of surface features that are coplanar. The output consists of features with cut holes wherever the surface features were contained within or intersected other surface features.

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. For more information, see Transformer Parameter Menu Options.
