scale fillets in dynamic block

Could somebody help me with this HSS dynamic block, please?

I attached the drawing with my masterpiece!:wink: I’m trying to change the radius for interior fillets, but something is wrong. The radiuses are scaled, their position is alright, but they are separated from the lateral sides.

How can I fix this?

Thanks in advance for your time.

first off I have to ask why? I have a HSS block and it's drawn 1"x1" with 1/16" sidewall, and I scale it to 5x5, 4x4, etc.

However, I attempted what you asked with a bit different approach. See attached. You may be able to make all 4 corners change at the same time with Distance Multipliers and Chained Actions.

You must have right about the distance multipliers and chained action. I didn’t try those, but I found much easier to use Constraints and it did work very well. If you want, I can send you tomorrow my HSS dynamic block.

I’m really curious to see your work, but I’m having problem with your drawing, I see you changed the lower-right fillet, but it does not appear any modification by selecting different sizes. Are you using 2011?

I just did the one corner and I think I made the inner rectange a pline, then didn't like it and exploded it, so it was not included in the outer Stretch selection set.

It was just an idea, by no means a finished product.

Here is attached HSS dynamic block (dimensions are according CSA G40.20). Enjoy!
