2 Part cut?

I have a part to cut that is just a little past what I can cut. My machine’s max width “X” axis travel is 12", my piece is 12.5". I have about an 1" of additional space on either side and thought that I could cut half of it than flip it over and do the other side. Problem is I don’t see a way to stop it from trying to mill the continued side. Right now it wants to cut across some features that I don’t want messed up on the mirrored edge. Any ideas of how to do this with one piece instead of breaking it in 2 pieces and gluing them together?

You want to click on the tiling feature.

Maybe you can set it up on a 45 degree angle from corner to corner and get enough room to do it in 1 cut.

Let me add some background info to the original problem. This is for a cast iron shop; it is a pattern for them to make a mold off of. Due to its complexity, I made it in another program and imported it in using the STL file(I attached it below). I thought I could just do what other users did prior to the Tiling option and put a shape over a portion of the part with a zero depth. Unfortunately, I don’t know if easel can’t handle adding extra shapes to the file, but all of those options disappear once you import an STL file into Easel. I’d just do this in 2 parts and glue them together, but the customer is worried about warpage when they go to make the mold from it.

I’m stalled of how to proceed at this point.

I’m looking at your object. You’ve got draft on it, so I think you’ll have to do it in two parts. Do the top, and flip it over to get the roundovers on the bottom. This means the small section would be below the x and y axis to do it more easily ( I think:-).

Yea, I’m aware of it. The draft is for the casting guys per their request. Matching it up exactly is going to be the big issue. Maybe I’m just trying to do something that is a little bit beyond what my machine can handle
