I’ve been using FreeCAD, LibreCAD and Qcad (Qcad is pretty good) to make metal part designs for things like fan brackets and extruded heatsink drill plans. When I visited my local machine shop, they were all on Macs and appeared to be invested in SolidWorks.
I’m not excited about the prospect of paying kilodollars per year for just the occasional design. Please let me know if there is a more affordable program that would give me better usability than Qcad to help interchange drawings/models with my local machine shop.
Update:
I took the plunge and I am liking my transition to Onshape a lot! The user interface is a bit different compared to Creo I learned in univ, but it has all the functionality as the expensive CAD software.

I have been having fun with the be quiet! LightBase custom 3D printed feet contest.
