Re: Sheet Metal modeling - pad error with arc of ellipse

To fix it: Delete the horizontal construction line Delete the https://www.freecadweb.org/wiki/images/thumb/7/7d/Constraint_PointOnObject.png/32px-Constraint_PointOnObject.png point on object constraint With the mouse, draw a box over the point where the ellipse and the vertical line apparently meet...

Sheet Metal modeling - pad error with arc of ellipse

Dear all, We are preparing a sheet metal part with bends, based on a padded 2D sketch. The 2D boundaries contain holes and an arc of ellipse and fails to pad for applying a thickness. I wonder if any user have faced a similar issue when applying the part design pad function - and how to overcome ? (...

Re: Sheet Metal bending

I think there are two separate issues : FreeCAD has an underlying weakness regarding internal topological identification. Basically, vertices, edges and faces are assigned ID numbers randomly. When you change a property, the object is recomputed, and if the number of faces changes, then the previou...

Re: Sheet Metal bending

I mean you cannot make gaps after all bends are made, because bends are mapped on a face. So new gaps creating new faces, and freecad are puzzled. :lol: And if you have to use freecad usually, you should use the new features of 017 (Part Design) ;) Hi GlouGlou, Thank you for your feedback. If I und...

Re: Sheet Metal bending with gaps

Questions: 1) Any ideas or tricks for introducing a gap of e.g. 4mm at the top of the right bend, which does not impact on the other bended flaps (e.g. BendTop)? You should make gaps before others bends to avoid faces conflicting . Good morning GlouGlou, I do not figure out how to overcome this iss...
