Fit rectangles inside surface?

[Cumberland]

Hi all. I do need to find a way to fit some rectangles (BB) inside of the corresponding planar surfaces (Top srf) by means of moving, scaling or rotating them without changing the XY proportions but I can’t find a proper way to achieve this goal.

I do tried a lot of thing without any good results. If somebody have any ideas on how this problem can be solved, please help.

Could this be a way?

This is just a sample. It should be made automatically for a few hundreds different parts without my intervention. Otherwise I can move, scale and rotate by hand.

I’ll try it this way.

Not exactly what I am looking for. This solution uses bounding box for the “Top Srf” but I do need to fit inside of the shape not inside of his bounding box. For this one of the shapes do have a hole in the middle, to find a way to fit the rectangle between the boundaries of the “Top srf“ shapes.

Your problem is not simple as you have rectangle that doesn’t fit in some shapes.

You can have the maximum circle(s) using that

OpenNest 2 Duplicate Geometry

The best way is to work properly and and data well organized, Datatree with surface and datatree with brep, tags … As it is not here a way to deal with that. As it is also not ordered I add to check which center gravity is near the other center of gravity … [image] Then place Tags not in thin air but on a real surface, so I reuse my tools (check the displacement I used (0.254), it must be half the thickness.

This doesn’t seem to work

Placing a Rectangle Inside an Irregular Polygon

Hello I think you can use Minkowski difference, it is in Clipper plugin You’ll have to place your rectangle centered on 0 on XY plane (or other if you specify) Then plug this rectangle to A and your polygon to B. It will output 2 curves. The second curves is the maximum polygon to place the rectangle inside your polygon. WIth that you could find the optimum position [image] [image] [image] [image] rectangle inside polygon.gh (12.5 KB)

I tested Wordle but it is long.

perhaps OpenNest could be better ?
