How can I prevent an entity in a dynamic component from scaling when that component is resized dynamically?

An example:

If I have a 12"x12"x3/4" board with a 1/8" radius around the top corners, how do I prevent this radius from changing if the board dimensions are changed to say, 24"x24"x1"?

You need to divide the “board” into sub-components so you can Move the radiused corner components instead of scaling. You can hide the edges and faces between the components so it looks like one piece.

You have to divide the board into a rectangular piece and a set of round edged pieces, and position and size them separately to keep the 1/8" radius from scaling.

Looking like this (if I’ve understood the shape of the board correctly):

Make a component of one edge (one along red axis, one along green, if the DC isn’t to remain square) then mirror them to replace the loose geometry on the opposite side.

Clean up any internal edges or faces, build your DC, then hide the edges where the pieces meet.

See this post for a conceptually very similar issue and the solution.

> hello. hope you are well, Is here a way to change the radius of the 4 corner and the dimension of the box independetly with DC i cant figue out how to do it. Thank u for ur time Have a nic eday

PS. As usual, Dave gets there fastest! He’d finished replying while I was typing. Reminds me of one of the US WW II generals (can’t remember which one) whose recipe for success in battle was “get there firstest with the mostest.”

PPS. I thought it was WW II - maybe Patton? - but a google search says it was Nathan Forrest in the US Civil War, and the quote was later mangled, apparently first in print by the New York Times in the early 20th C.

More accurately, it was “Get there first, with the most men” according to Encyclopaedia Britannica - [Nathan Bedford Forrest | Biography & Facts | Britannica](https://www.britannica.com/biography/Nathan-Bedford-Forrest).
