Circle Dynamic Block

[penroyaltea]

Hi everyone, I am trying to create a dynamic block where I can change the diameter of a pipe, while keeping the insulation around it always 20mm.

I have managed to scale the whole thing, but would really love some guidance on how I can keep the insulation (grey) the same size, but make the pipe (orange) a different size.

I can't seem to find the constraints menu, if this is involved? Looking at the guides, they haven't been that useful so you're my only hope.

how do i hatch the middle pipe please? I cant seem to add the hatch to the middle without breaking the block

@penroyaltea Try the updated block attached. I've also made it so the minimum size of the pipe is 1 unit so the block doesn't break
