Simulate Early, Simulate Often... In Rhino
I need to analyze a 1" square extruded aluminum arm but having difficulty in forming a solid from the components that make up the arm. If I try a Boolean union of all the components, the inside surfaces are then not part of the solid and SnS will not recognize the resulting solid. I have attached the Rhino file if someone can suggest a solution.
Jay, this question came up before. The correct Boolean union should preserve all internal details of course, but Rhino does not seem to handle this correctly.
An earlier discussion proposed a workaround, which may or may work for you. It is basically a hack that takes advantage of the fact that Scan&Solve is able to ignore features that very small relative to the element size. I personally do not like suggesting this, but it seem to have worked for others.
But I encourage you to send a note to Rhino developers. They really should fix this.
Thanks, I expect that this workaround will solve my immediate issue. Will work with McNeel to hopefully get a more permanent solution.
