![]() Attached are screenshots of the sketch in part design, the error message I get when I try to create a pad, and the FCStd file. There are a lot of overlapping elements which was mentioned when I googled the problem, but they're in construction mode, and without them, the sketch would no longer be contrained. The sketch is fully constrained, and the beginning of each arc is coincidental with the end of the previous so I can't find any break in the profile that would cause the "broken face". ![]() Whilst the shape is, as far as I can tell, a single unbroken profile, I can't create a pad of the sketch, which instead gives me the error "Failed to validate broken face". It's a shape consisting entirely of arcs, which I've made by using a load of circle in construction mode, and then effectively tracing the shape from where the circles contact. I'm trying to create a set of acoustic guitar plans and am drawing the body shape. I'm having some trouble creating a pad out of a sketch. ![]() And only do more sketches when I can't do it from the same base plane. I usually make one sketch (if I can get away with it) that has everything I need to do, and then extrude the portions as I need them. And I'm comfortable using expressions when needed, etc. In F360, I usually start with a Dimension sheet, put in all the variables I want, and design everything that way. That sounds kind of similar to what I've done in F360. Well, I normally do have things planned out. You can search the forum for discussions. If you try to follow, note that completion is broken in expressions - type in the name and it will work.ĭownside of this approach, IMO, is that you need to have things pretty much planned out before you make your master sketch as changing its geometry (as opposed to dimensions) later may be a fragile operation. Is there any type of "If this, then that" kind of cheatsheet / cookbook around for F360 refugees ?Įdwilliams16 wrote: ↑ Fri 8:53 pm will give you an idea of the Master Sketch workflow. I looked for some "guides" for people coming from F360 and found a couple that were very cursory. A lot of this feels familiar, but obviously there are some differences. I felt pretty comfortable getting around in F360, including using variables and whatnot. Thanks, I'm brand-new to this in FreeCAD. For simple models, you don't really need any of them. It is one way to consolidate some of the parametric information, but there are others - spreadsheets, dynamic data, expressions that you might prefer. There is a workflow using a master sketch from which you copy the relevant bits for a given operation. The latter requires that the sketch must consist of closed curves, nested no more than one deep, with no T-junctions or stray lines or points. Such operations are not allowed to create additional bodies - and they must be unambiguous. making 3D features from sketches, use the entire sketch (excepting construction lines), not some chosen subset of it. Putting it another way, pads, pockets, lofts, sweeps etc.
