Start a simplification operation
Once you have specified a simplification definition, you apply it to the part or assembly. Click Simplification and then, in the Manage group, click Execute to display the Execute dialog box containing the following:
Owner: Specifies the owner of the simplification definition.
FeatName: Specifies the name of the simplification feature (that is, the simplified part).
Part Simplification: Specifies one of the following:
On: All parts are simplified according to the parameters specified in the Geometry and Face menus.
Off: Only structure parameters are applied as specified in the Structure menu.
Structure: This command lets you select the type of structure. The element ID of the assembly is kept for both Merged and Fixed options.
Merged:
Simplified parts are merged into one or several non-connected volumes.
The structure below the simplified assembly is replaced by new parts.
The new parts contain new geometric elements (faces, edges) with new element IDs.
If mass properties are requested, the complete assembly is assigned a mass property
Fixed:
The result consists of the simplified parts of the assembly. Non-relevant parts may be empty.
The assembly structure is kept unchanged.
All element IDs of subparts and subassemblies are kept.
The element IDs of the remaining geometric elements (faces, edges) are kept.
If mass properties are requested, each part is assigned a mass property.
Preview: Produces a preview of the model. When in preview mode, Original is active to allow you to return to the original model.
