If the current node in the geometry sequence is before the node preceding the selection node or after the selection node, the selection is not visualized (because the selected object or entities might not be visible in this state). In this case, the Build Preceding State button appears instead of the selection list (this also applies for nonexplicit selections in some selection nodes if
From selections is selected under
Input Entities). To create a state in which the selection can be visualized, click
Build Preceding State or click the
Build Selected button (
). To rebuild the entire geometry, click the
Build All Objects button (
).
To create these selections, click the geometry object node in the Model Builder and then select the
Resulting objects selection check box in the
Settings window’s
Selections of Resulting Entities section. The selections then become available with the name of the geometry node (
Block 1, for example) in subsequent geometry nodes. To make the selections available in all applicable selection lists in the
Settings windows for the physics nodes, material nodes, mesh nodes, and so on, select an option from the
Show in physics (
Show in instances if in a geometry part) list:
All levels, to make the selection available for all geometric entity levels;
Domain selection (the default for most nodes);
Boundary selection;
Edge selection (3D only);
Point selection; or
Off, if the selection should not be available outside of the geometry sequence. Not all entity levels are available for all geometric primitives and operations. There are no explicit Selection nodes for these selections. For example, for a 3D Component model with a single
Block node, the
Selection list contains the selection
Block 1, which for a domain selection is the single domain, and for a boundary selection consists of the six faces of the block.
