I have a simple assemby - a long vertical cylinder with a small diameter cylinder passing through it at right angles to form a pivot pin. The two cylinders are unioned together and the “boole"is set as a solid body. I have two cubes (one on each side of the tall cylinder) set as collision objects.
When I start the animation the assembly falls until the pivot pin hits the top of the two cubes and stops. So far so good.
If I cut the two cubes such that there is a semicircular hole cut out of the top, the assembly stops falling when it hits the edge of the cube - ie it doesnt fall into the cutout.‘If I cut the holes in the cemter of the cubes (or in the cubes’top edges) and position the assembly with the pivot pin in the cutout it of course flies out of the cutout.
How can I cut holes in the two cubes so the assembly is trapped with the pivot pin sticking though the two holes? I want the tall cylinder to hang between the “cubes” and swing about the pivot pin as it is hit by other objects (actually a Realflow fluid)
