    Geometry

    Adrian Williams

      I recently offered to help a colleague with some 3d maths saying that if the sketch entities turned black then a solution could be found for the limited available information. So I sketched up his problem and the sketch solved.

      He then asked if I could tell him how the calculations were done.

      I can't but I hope someone can.

      I can supply details of the problem if anyone wants.

      Thanks in anticipation.

          Please post it here.

           

          The answer is probably the fact that SolidWorks is a virtual reality medium. If I draw a line 20" long in a sketch, that would be similar to having a rod cut to length at 20". Now, if I weld that rod to others, also predefined in length, at predefined angles and attach them to the ground (read the origin) I will get a rigid, immovable part.

           

          So there is no calculation involved, you just mirror what you would do in real life.
