Enlarge button cutouts

[socialstijn]

Hello,

Hope you're all in good health!

I have converted a DWG file that was meant to be cut on a laser cutter. I'm looking to print in on my 3d printer, but because of my limited experience with Fusion 360 ran into a wall. Could anyone point me to the best way to make the button cutouts  1.5mm larger while keeping the same corner radius? When using the offset tool it changes the radius.

I have attached a screenshot for your reference, as well as the actual file. Any tips are greatly appreciated!

I have never had this to happen before nor have I ever tried this so this is a shot in the dark, but have you tried the sketch scale option under the modify tab. I don't know what the outcome will be or if it will affect the radii of the corners. You would just have to place a point in the center of each rectangle in order to select that point when using the sketch scale but like I say I don't know if that will affect the radii of the corners or not, just a suggestion.

Are you wanting to change each of the smaller rectangles inside as well as the outside rectangle or just the outside rectangle or what?

[socialstijn]

Yea I only want to change the  small (button outline) rectangles for now. Thanks for the tip, I will give that a go!

So the best way to find a center, would I just draw 2 lines from each corner?

[whittakerdw]

You could do that. I just found the midpoint of two lines perpendicular lines and used that as the center of the rectangle.

it would probably be worth you while to figure out how to model this from scratch.  Messing with imported curves can be a paint.  this one isn't even situated symmetrically around the origin.

Here's a model and screen cast showing an approach. let me know if you have questions-
