I was running the ULP's by clicking ULP in the Automate section of the Utilities tab and searching mount and mountsmd. Run that way, the bottom placement file was always blank. I also tried the mount-smd-tht ULP and it seemed to still work. And then I tried creating PnP files from the CAM processor and yes, that seemed to work.
How does the CAM processor create BOM files and PnP files? Does it use ULPs or is the process hard coded?
Is the command line interface and ULPs and scripts going to get continuous support? Are people writing new ULPs?
The problem is that I had optimized my workflow and then there were a lot of changes to Fusion 360 and now I have to figure out a new workflow by experimenting and asking the Autodesk Assistant for how to do things, which takes time to make sure the information I want is being generated. I was skeptical for the usefulness of the Autodesk Assistant, but it has been really helpful sorting things out since the Fusion 360 documents are poor.
