I curious why draft not separate trim function individual than to group it into one command trimex (trim, extend, extrude). No need delete face then trimex (to extrude).Īlso I face abnormal behavior of trimex for trim line in draft (hard to trim to what I want, with confuse of mixture press of ctrl, shift, alt, where position of mouse in use) but no problem straightforward and clear use of trim in sketcher. I can immediately use part design to pad a select sketch (to extrude). Since in your example rectangle and circle if I create in sketcher. It seem to me sketcher is more advance than draft. In your DXF, there are 10 closed profiles: If you want the curvature of the inner face to remain cocentric (and therefore have the radius shrink), you'll need to use Part workbench and the 3D offset tool (after making a Shell object copy of just that face using Curves WB "extract subshape"), and then using Boolean Union to join them together.Draft can only create a face from a single closed profile. Now, this method will keep the curvature of the inner face a constant. Newer users to FreeCAD can forget that when working with Pad/Extrude you can just use any face and extrude on a normal (as long as the surface/face only has one normal)! It's a very fast way to generate features, and you can tune in their size afterward adjusting properties in the object tree. in my example i chamfered the back corner for fun. Pad up to the bottom of where you might want the horizontal feature, pad up again for the height of the hook, pad out on the inner radial face for the width of the hook. Super simple to create the shape that you want from one sketch, if you extrude the vertical feature which is padded in two moves. Fewer steps too, and no awkward BaseFeature.
If it's a tight curve, the thickness will not be even and you'd be better off skipping the Part workbench bit and drawing a second arc with the same center as the first one, closing the ends, then padding it.
If it's a shallow curve (as it appears to be), then this should be fine. :)Įdit: Note that this simply pads linearly. Select this new BaseFeature and click Pad.īonus: In the tree, select the pad and toggle Refine to true to eliminate the seam at the top. Go into Part Design workbench, drag the new Extrude component from your tree into the body to automatically create a BaseFeature to tie them together (or use the shape binder). Go into Part workbench, select the new arc sketch, click Extrude, reverse it, and give it a height (this is your vertical dimension). Create a new arc that's coincident with this new red one (use coincident constraints on the ends and either tangent or equals to match up the curve). Select the tool "Create an edge linked to external geometry" (or click X) then select the inside arc. Alternately, select the top face then create a sketch, or create a datum plane and create a sketch (the end goal is a sketch on the exact plane of the top surface).Įdit the sketch. R/flossCAD (for r/CAD refugees) r/LibreCAD r/OpenSCAD r/SolveSpace r/SweetHome3d r/opensourceĪssuming the top is flat and parallel with an existing plane, create a sketch on that plane, close the sketch, adjust the Z to match the height of the object.
