Fusion Manufacture question

I am working on a way to do double sided milling without using dowels. In the Fusion Manufacture environment, I use ‘arrange’ to lay my model components down in preparation for milling. In ‘arrange’ I set up an ‘envelope’ that is slightly larger than the room I need for all my components. I then use an oversized piece of stock on the mill. The very first operation I need to do is to have the mill cut one axis, either x or y, to be exactly the size of the ‘envelope’.

Problem is, Fusion shows me the ‘envelop’ while I use the ‘arrange’ function but once I try to set up tool paths, this envelope goes away and I can’t perform a machining operation on it. Is there any (reasonable) way of doing a profile cut of the edge of the envelope as part of my machining operations?

I have come up with a way but it is immensely cumbersome and error prone and am wondering if maybe I am missing something. The only other thing I have come up with is to cut stock to the size specified when doing the envelope setup in a completely separate Fusion project before I load the gcode file for the actual project. In other words load a gcode file to cut the stock to the required size, run the file, load the gcode for the actual project that I need to cut and then run all my tool paths from this second gcode file.

In case anybody is curious why I want to do this …. if I have the mill cut my blank stock to the exact size that Fusion is expecting on at least one axis, if the work piece is registered against a fixed edge on x and y, I can cut side one and just flip the part to cut side two. No dowels required. The ‘arranged’ parts are cut out half way with a profile operation during side one operations and then cut out all the way after the side two operations have been done. At this point I have a bunch of parts that can all be double sided while using a single piece of stock and no dowels required.

I’ve done a fair amount of 2 sided carves with fusion. I don’t use the arrange tool though. I create fixtures for the second side to locate them and separate WCS origins. The second side is zeroed on the fixture.

I had filed a case with Fusion support and they got me on the right track. I was arranging my components on a plane and it was simply a matter of doing the arranging on a sketch. Embarrassingly simple :frowning:

BTW, I use arrange because I will do several components at a time in one piece of stock and none of this is a production run so fixtures are ( IMHO) not the right choice. I have a stop block for the x axis and one for the y axis which register the stock. In my first operation, I cut one of the axis to size as per the setup envelope. I then do all the side one operations, flip the stock (with all the components still as one piece) along the axis that I trimmed in the first operation. This again registers the stock and I can proceed with the side two operations. When done, all the components are only held in place by tabs and more or less fall out of the stock.

A lot of he things I do kinda require a fixture or at least that was the workflow I could wrap my brain around. I’ve taken to modeling my stock and manually arranging the parts if its only 2d operations on both sides. Just have to do another setup to change orientation and box point location.
