I am trying to build a Style feature in Proe. I select Style, surface then I select 4 curves (while holding the CRTL key). Proe show me the initial surface! Now I want to add some internal curves. All is OK if I add one or more single curves, but I would add two (or more) single curves as a unique internal curve. The Help says to press the SHIFT key, but I am not able to do this.
Thank you for any help
