Replacing geometrical elements  

In this scenario you will replace GSD feature.

1. Select Extrude.2 from the specification tree. Right-click to display contextual menu and select Replace command.

   The Replace dialog box appears.

   The Replace dialog box allows you to replace the FTA features during the Replace process. All the FTA features that are applied to the geometrical elements of the replacing GSD features keep the same behavior than before the replace (move, cross highlight, filtering, etc).

2. In the Replace dialog box, to update the With field, click on Extrude.1.

3. As soon as the With field is updated the Replace Viewer dialog box is displayed.

   If there is a unique solution to replace the geometry, it is directly replaced and the Replace Viewer dialog box is not displayed. If there is no unique solution to replace the geometry, then Replace Viewer dialog box helps you to make the choice. In the example below, select the corresponding face for Face.1, Face.2 and Face.3.

   	If the Delete replaced elements and exclusive parents option is selected, then after replacing geometries by others, the replaced geometry will be deleted in the end.

4. Click OK.
   You can see that the FTA features have moved.

More on Replacing Elements

• Associative views are updated after their input geometries have been replaced. The transfer of FTA annotations present in the view, depends on, if transfer in the new associative view is possible or not. If transfer is possible, then annotations are transferred to the new associative view, if not annotations turn invalid.
  In this case Fill.3 (pink fill) is replaced by Fill.4 (green fill). You can see that the dimension has turned invalid.

• Constructed Geometries are updated after their inputs geometries have been replaced. CG is updated according to the replacing geometries.
  In this case Fill.2 (green fill) is replaced by Fill.3 (pink fill). You can see that the CG is updated as the Fill is replaced.

• Restricted Areas are updated after their inputs geometries have been replaced.
  In this case Fill.2 is replaced by Fill.3. You can see that the restricted area is updated as the Fill is replaced.

• The Replace command is not available in Product Context.
  The replace functionality does not have the same impact on FTA features created in Product Context. Even if the FTA features are pointing to a replaced geometry in Part context, the FTA features defined in Product will not migrate after replace.
  • If the Delete replaced elements and exclusive parents option is selected, FTA features defined in Product on the replaced geometry will be invalid after the replace.
  • If the Delete replaced elements and exclusive parents option is not selected, then FTA features on Product will remain linked to the replaced geometry and status will be same as that before the replace operation.
• On setting the Do replace only for elements situated after the In Work Object option is selected (using Tools > Options > Part Infrastructure, General tab, Replace field), FTA features that are pointing to elements situated after the In Work Object will follow these elements after replace. FTA features that are pointing to elements situated before the In Work Object will not be impacted.
• When creating a generative dimension on hole feature, the depth generated dimension point some sketch elements and will not follow after replace because replace does not take into account this type of element.
  In this case Point.1 is replaced by Point.2.

• Pre-R18 FTA features, will not migrate after the replace of a GSD feature.
