Lately I’ve been doing practice exercises using the drawings from www.studycadcam.com. One thing that has repeated frustrated me is drawing the places where fillets meet at complex corners. I’ve tried follow-me, Fredo corner, Curviloft, etc., and still keep running into situations none of them handle.
Here is an example I came across yesterday. There is a fillet running one way to this junction and a rounded corner meeting it from another. I have two questions:
How would a real situation like this be shaped? The transition from concave to convex baffles me. The drawing from the exercise set gives no clue. Orthographic views misathis sort of thing, and the 3D view has it partly out of sight on the back.
If there is a good answer to #1, how would one draw it in SketchUp?
Here’s where my SketchUp model got to:
