Restricting Angular Movement in 2D Mechanism Sketch (by MattE)
Hi. Query is as the thread title: Is it possible to restrict the arc through which a radial arm can move, such that it hits 'stops'?

I have tried driving the mechanism by stepping the radius arm in question, but for a good part of the motion that the entire mechanism goes through, the arm is static (on one of the said 'stops') so that I means I can't track the full motion.

Thanks, Matt

One approach is to use construction lines, one to bisect the required arc of movement, and one from the end of the arm to that bisection line. Set the length of that line to restrict movement, (its length when normal to the bisection line). You can temporarily constrain the arm to it maximum angle on one side of the bisector, and the constraining line to 90 degrees to get the length of that line.

There is feature request on adding "Inequality constraints"

- https://github.com/solvespace/solvespace/issues/81

BTW, while it not merged yet you could use existed constraints. I will try give you an example soon.

What version of SolveSpace you use and what is your OS?
