[solved] Array of bevelled holes in a block

Post by instance »

I'm trying to create an array of bevelled holes in a box and can't figure out how to do it without resorting to macros. A simplified version of the problem is attached.

I've created the hole with a sketch and revolution:

My first thought was to make an array of these, then cut them form the box, but MultiTransform doesn't like disjoint solids. fine then, I'll make a box with a hole in it, size the box so they're adjacent and then use that.

But no, that's giving me an error: "only additive and subtractive features can be transformed".

My conclusion is that I'm just taking an incorrect approach and need to try something else, but I can't see what that might be. Can anyone offer some advice on the best way to get this done?

That will work for the current problem, thanks!

Still curious how I could solve this problem if the hole profile is more complicated... any ideas?

Just make the revolve a subtractive one (groove) and then pattern as usual.

If it is even more complicated, you can also use multiple features in a single pattern operation.
