Boolean Mesh Operation Properties

The boolean operation uses CAD bodies from the latest description for this operation. The root description of the output part has CAD bodies from which the discrete surface mesh is generated. If CAD bodies are not available on the latest description of input parts, the boolean operation performs a discrete boolean on the surface mesh.

Tessellation Options

Controls the tessellation parameters. Click to the right of this property to display the Tessellation Options dialog. The options presented here are:

• Mark Feature Edges — Allows you to specify which of the mesh edges that lie along CAD edges are marked as feature edges. See Mark Feature Edges.
• Sharp Edge Angle (deg) — Creates feature edges from edges of attached faces that make an angle sharper than this value. The default value is 30 degrees.
• Tessellation Density — determines the level of surface refinement on the geometry after imprinting.

Activate the Show Detailed Tessellation Parameters option to reveal more parameters. See Show Detailed Tessellation Parameters.

Tolerance Type

Defines the tolerance method to use in the operation. The tolerance methods used in the imprint operation are the same as that used in 3D-CAD. The options presented here are:

• Precise — Uses the default internal model precision of 1.0E-5 m as the tolerance. This tolerance setting requires that faces of separate bodies be within 1.0E-5 m of each other. This option takes a minimum amount of computational time and works well for all coincident faces and surfaces.
• Tolerant Faces and Edges — Reduces the model precision by using a higher tolerance value that you provide in the Tolerance property on all the edges and potential overlapping face pairs in the model. This option causes any subsequent operations to use the lower precision model. This option is only available for the unite mesh operation.
• Tolerant Edges — Reduces the model precision by using a higher tolerance value that you provide on all edges in the model. This option is available for intersect and subtract mesh operations.

Applying a tolerance value can introduce a deviation in the resulting geometry within the limits of the supplied tolerance.

The boolean operation uses the discrete surface mesh from the latest description of input parts for this operation. The root description of the output part does not have any CAD bodies and the discrete surface mesh is generated from the input surface meshes.

Remesh Intersection Curve

• Activated — Faces near the intersection curve in the output parts are remeshed. See Intersection Curve Remeshing.
• Deactivated — Deactivated by default. Faces near the intersection curve in the output parts are not remeshed.
