Multiple Extract lets you extract
sub-elements (curves, points, surfaces, solids, volumes and so forth) that are
joined into one element.
Before you begin: Create a 3D shape containing geometric elements.
Select the elements to be extracted.
If the first selected element is a curve (or a point, a surface, a volume), the next selected element is necessarily a curve (or a point, a surface, a volume).
Note:
To remove an element from the list, re-select it in the work area.
Select the Propagation type.
Point continuity: The extracted element is created according to point conditions and therefore has no hole.
Tangent continuity: The extracted element is created according to tangency conditions.
Curvature continuity: The extracted element (necessarily a curve) is created according to curvature conditions.
No propagation: only the selected element is created.
Select the Federation check box to generate one or more
groups of federated cells according to their connectivity.
Important:
This option applies to all the inputs that lie on the same
support.
The cells that are not propagated are never federated, even if they
are in contact with other federated cells.
Click OK.
If the result contains only one domain, the multiple extract operation is terminated.
If the result contains more than one domain, you can manage the multiple result in the Multi-Result Mangement dialog box.
