Error Using Sketches Under Feature - Help Needed


New member
I am struggling to create a rib feature in my part, I was able to create one and then something happened where Catia is inserting my feature into the part tree above the sketches. It then gives me this error when I try to select the sketches to use for the rib feature:

"Impossible to select because it's located after the feature "Rib""

Any suggestions on how to fix this so I can create a rib feature using these sketches would be very appreciated.

Right-click on the last sketch, and choose DEFINE AS WORK OBJECT. This will underline the sketch you chose, meaning that the next thing you create (Rib) will be located after that sketch in the tree.

This behavior is because your options are set for Hybrid mode.
