Creating Boundary on 3d profile

[chris.williams34RYS]

I am trying to machine this part inside a boundary. I only need to machine the blue and purple as the rest is already wired from a block. I cannot seem to figure out how to make a boundary for it. new to fusion please help.

Hi.  You may be able to do this with a boundary.  You can also use touch/avoid surfaces.  Are you able to upload your file?  If so, it would be easier to make an example.

Here is the file. I do not see the avoid/touch surfaces option when looking at the geometry tab. maybe I need to convert the file?

When I need to create a boundary, what I do is go into design, pick a surface I want to use for my sketch, and then project items that I want to use for a boundary. If needed, then I add lines or curves to complete the sketch. There might be a better or faster way, but this has served me well in the past. See attached.

used wrong wile the first time here is the correct one

I do see what you saying here and I tried to do that yesterday but projection works differently here than I'm used to and am having trouble making the projection usable for a boundary.

Is this what you are looking for? If you edit the sketch, the purple lines are projected and the black lines are ones I added. If you are starting from a wire cut blank with all of those grooves cut into already, you can play around with using that as your starting stock to save time with the 3d surfacing toolpaths, Fusion is model aware so it can shorten your machining time if it knows what the exact shape you are starting from.

yes this is what I was looking for now I just need to figure out how you got the black lines on the projection. I will play with the stock values. I have been doing the training videos but this is all new to me. I have only been doing 3d machining for the last 6-8 months. been a wire EDM/2d machining guy for 20 yrs.
