From the Virtual Operations menu (on the context menu when right-clicking a 3D
Geometry node or on the
Geometry ribbon), choose
Remove Details (
) to add a node with settings for automatically remove small details from the geometry. Small details include short edges and small and narrow (sliver) faces, which may complicate the meshing and make the model more difficult to solve. The
Settings window contains the following sections:
The default in the Mode of operation list is
Automatic. Typically, use the automatic mode first. The
Remove Details operation generates and builds a local sequence of virtual operations. You can then switch to
Manual if needed to inspect the added virtual operations and fine-tune and add more such operations. When you have built the
Remove Details node and the
Mode of operation list is set to
Manual, the created virtual operations are available as subnodes to the
Remove Details node. Alternatively, right-click the
Remove Details node and choose
Edit Generated Sequence (
). You can also then right-click the
Remove Details node to add more virtual operations. If you want to restore the generated sequence of virtual operations, choose
Reset to the Generated Sequence (
) from the
Remove Details node’s context menu.
From the Detail size list, choose
Automatic (the default),
Relative, or
Absolute. If you choose
Relative the
Maximum relative size field appears (default value: 0.001). If you select
Absolute, the
Maximum absolute size field appears (default value: 0.001 times the size of the geometry’s bounding box). When you build this feature, the
Maximum relative size and the
Maximum absolute size are set to the values that are used, which can be useful when you have set
Detail size to
Automatic.
The values in the Continuous tangent tolerance field (default value: 5 degrees) specifies the maximum allowed angular tangent deviation across a vertex or edge to be ignored.
This section contains information about the removed details: In the Type of removal column, the types of details that have been removed are listed. In the
Removed entities column, the number of entities for each type of remove operation is listed.
Click Build Selected (
) (or press F7) to build the geometry up to and including this node, click
Build Preceding (
) (or press F6) to build the geometry up to the node preceding this node, or click
Build All (
) (or press F8) to build all nodes in the geometry sequence.
