Specifying Rebuild Requirements for Cosmetic Changes

You can use Mark assembly as modified when cosmetic changes are made to referenced documents to specify rebuild requirements for nonessential changes.

When you select Prompt or Never and make a cosmetic change, the model is not marked as modified. In the menu bar, the document name shows with brackets and an asterisk.

Modifications that do not require a rebuild:
  • Adding, modifying, or deleting reference geometry in a part.
  • Changing the visibility of reference geometry in a part.
  • Adding, modifying, deleting, or hiding a sketch in a part where the sketch does not drive any geometry.
  • Hiding or showing bodies when the referencing assembly includes hidden bodies or components in the mass property calculations.
  • Hiding or showing bodies when the referencing assembly does not include hidden bodies or components in the mass property calculations.
  • Adding, modifying, or removing a part appearance.
  • Adding, modifying, or deleting a decal from a part.
  • Canceling changes to a feature in a part.
To specify rebuild requirements for cosmetic changes:
  1. Click Tools > Options > System Options > Performance.
  2. Under Save, select Mark assembly as modified when cosmetic changes are made to referenced documents and select an option:
    Always Rebuilds the assembly for all cosmetic changes.
    Prompt Asks if you want to rebuild for each cosmetic change.
    Never Does not rebuild the assembly for cosmetic changes.
