(...) More or less... there are 4 tangents to the 2 cylinders that happen to be on the circles. (...) Some thoughts that could perhaps (with [lots of] work) lead to an iterative solution: - Select one of the circles, then choose one radius of this (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)

(...) Yes. This *is* the ultimate (and probably universal) solution, although we probably need to be able to find one of four cylinders between any two circles in 3D space. You are thinking in terms of pulleys always on the outside of the band. With (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)

Hi Kevin, I think common tangent to circles is too restrictive, since rubber belts tolerate quite a lot of misalignment. ((URL) the problem should be reformulated as: Two circles in 3D space define two cylinders orthogonnally extruded from them. (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)

(...) In LDView, I do a few things. First, I check to see if the file I just loaded is a part. In order to be a part, it has to satisfy two criteria. First, it can't be the child of a part. Second, it has to either be in the LDraw Parts directory, (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)

(...) OK. Here's my rather convoluted analysis: 1. Find the plane of pulley A 2. Find the plane of pulley B 3. If they dont intersect, no tangent so stop here 4. Find the angle between them, call it T 5. Find the normal to plane A that passes (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)
