How can I find the middle point of a rectangular plate (an extrude from 4Point surface) in order to apply a point load on it?
The middle point should be done for the plate which marked with green. see the picute
Yeah, I noticed that. I won’t bother with your second file, I used the first one.
There are many ways to improve this model, the primary one being to copy the base extrusion by moving it up to where you want the top one.
You already have an ‘Upper point’ used as the center of a circle. If you move that up by the thickness of the extrusion, it should be the same as Area ‘C’ of the top surface?
More simplifications, including “load point” (cyan group), and it could be even simpler… Don’t know if you want a “solid” (“Closed Brep”) from this but I added it anyway: SUnion.
