Without seeing your document, it sounds like you are using fix in your subassemblies when you should be using group or the fastened mate. Fix only applies to the assembly you are in, so if you bring an assembly that has no groups or mates it will act as if you did nothing to the parts.

@dylan_allright your welcome. I was looking at some things while I was digging around in your file and a couple of tips came to mind. When you have multiple features that are identical and evenly spaced, look to use patterns to save some time. also I saw some repetitive dimensioning on circles in a sketch that could benefit from using the equals constraint. If you haven't done the fundamentals courses 'intro to CAD' at learn.onshape.com, highly recommended for speeding up the learning process.

Hello,

I teach high school manufacturing and am switching my classes from Fusion to OnShape. I really like OnShape CAM in Part Studio. But now we are trying to use CAM Studio and it is really kicking our butts. So far I have been teaching students how to set up a job in CAM Studio and we have made it all the way through creating tools. I was also able to reproduce our standard aluminum tool library in OnShape and share it with my students.

The challenges start with creating tool paths. I've been through all of the CAM Studio videos. I've read several blog posts. It just seems to me that everything is touting the possibilities of CAM Studio, but no actual projects are being demonstrated here. We are using the Titan-2M as our subject for introducing CAM Studio. It would be really great if there was a John Saunders/NYC CNC out there for OnShape.

I have created a facing toolpath that I can live with. I created a drilling toolpath that seems pretty good. But roughing and any kind of finish profiling is just awful. The best I could get while roughing had a full-speed slotting operation with a 3/8 endmill 0.4D through aluminum. That would just load up and break. It feels like there is no control over selecting specific pockets to machine, how deep to machine them, and the stepovers are ignored. It is also frustrating that in the Education Enterprise version there is no Adaptive or Trochoidal toolpaths; just "dumb" offset or parallel toolpaths. Adaptive and Trochoidal toolpaths promote progressive and then constant tool engagement which extends tool life. If we use "dumb" toolpaths, students will have loaded and broken tools more often. I prefer my students to succeed first, and then improve their skills.

Is anyone out there in the same boat?

Yeah, that's a difficult shape. It might be a good approach to surface-model that, maybe keep top and bottom separate at the chord for now, and then thicken, unite.

Maybe make it so that it doesn't come to an absolute point. I suspect there are zero manufacture-able wings that end in a point like yours does.
