Color
Volumetric features are displayed in purple in the 3D geometry as well as their corresponding icons in the specification tree.
Creation
Volumetric features can be created in both Geometrical Set and Ordered Geometrical Set environments and are considered as creation features.
Modification
Several modification features enable to modify a volumetric feature into
another volumetric feature:
- Split
- Diabolo
- All fillets (but the shape fillet) : edge fillet, variable radius fillet, face-face fillet, and tritangent fillet
- All transformations: rotate, translate, symmetry, scaling, affinity, and axis to axis
- Patterns:circular pattern.
Behavior
The following commands can be used with volumetric features:
- Delete
- Deactivate/Activate
- Parent/Children
- Datum mode
- Reorder (note that it is not possible to reorder the volumetric feature before its parents)
- Replace (a volumetric feature can only be replaced by another volumetric feature)
- Show/no show
- Stacking
Selection
When working with volumes or solids, the selection of the volume or solid prevails over the selection of a face. Edges and vertices can still be directly selected.
Here are the concerned commands:
- Affinity
- Axis To Axis
- Intersect
- Project
- Rotate
- Scaling
- Split
- Symmetry
- Translate
- Trim
To select a sub-element, you need to apply the ''Geometrical Element'' filter in the User Selection Filter toolbar. You can activate this toolbar by selecting the View > Toolbars command and clicking User Selection Filter.
- The icons on the left lets you filter elements according to their type (point, curve, surface, volume)
- The next two icons correspond to the filter modes:
-
(Feature Element Filter mode) selects the whole feature whether it is
a sketch, product, pad, join, etc. -
(Geometrical Element Filter mode) enables to sub-elements of a feature
such as faces, edges or vertices
-
