How to cut surface marked in black. It is a surface stiffener on a surface. What is the best method to do it and how ? Is it fine if i make a sketch and extrude it and use trim or split tool to cut it . But after cutting when i delete sketch which i used to cut surface, stiffener part again show up. Can i cut this part without unnecessary sketches.
I may be wrong but as far as I know you have to retain any sketches you use to either extrude or cut parts.
Delete the sketch, lose the feature.
