Got a warning email about my free CAD account - anyone else dealt with this?

I think the whole Onshape thing is just a big dependency risk. For me, the convenience of working in the browser from my workbench at the garage versus my desk at the office is worth the occasional headaches. I've got thousands of little designs, some for my old workshop equipment and some for custom camera mounts on my camera rig, and I don't want to risk losing that repository. I made a point early on to export critical assemblies regularly, especially the ones I've spent more than six hours perfecting. It’s a massive time commitment, but it’s my insurance policy against some automated script flagging 'commercial activity.' My biggest fear isn't actualy getting shut down; it's losing access to the work because the vendor changes thier pricing or retires the service. Backups are the only real defense.

I'm skeptical about just jumping to a local desktop application. I've tried Fusion 360 on my aging office laptop, and while it offers that complete ownership feeling, the install size and the processing demands are too much for my setup. My workflow relies too heavily on quick cloud access and real-time collaboration with a neighbor who helps me sort out some larger fixture designs. The trade-off for convenience is definately a bit of anxiety, but for the personal projects I run, I’ve decided the risk of manual exports is a worthwhile maintanence step.

I’ve dealt with the same issue because I design a lot of custom mounts and small repair parts for my home. It really isn't the volume of parts that triggers the flags, but what I think are the keywords in the file descriptions and names. If I label a design something like 'Precision Engineering Component for Commercial Application,' it is an instant warning sign, even if I am just printing one. The system is really just looking for commercial markers in the metadata. My approach for data security is to keep the masters off the cloud. When I finish a project that isn't going to change, I export the native file formats like the STEP files and store them on an external hard drive in a seperate folder. This way, if the service ever decides to restrict access or change the terms, I still have a complete, usable archive of everthing I’ve designed. It requires a little extra work to manage those local backups.

Moving to a local desktop suite feels like too much overhead for the scope of work most of us do. The convenience of working everywhere outweighs the risk, as long as you keep a local, encrypted copy of your work separate from the service's own storage.

When my old cloud account got a similar flag a couple years back, the thing that cleared it up was a plain email listing what I actually print, like a hinge repair for a garden gate and a bracket for the shed door. Took about three days for them to reply and it never came up again. So keep the description boring and factual and respond fast.

On the backup side, I do a monthly export of my 30 most-likely-to-be-needed parts and stash them on a USB stick in the drawer by the printer. It takes maybe ten minutes and covers the designs I'd actually cry about losing. Everything else can be remodeled if it came to that.

Agree with the poster who said backups are the only real defense, that lines up with how I do it. I keep a USB stick in my desk drawer with exports of anything I might need to reprint in five years, and I redo it whenever I finish a project rather than on a schedule. The detail that saved me once was exporting both a STEP file and a screenshot of the assembled part, because two winters ago I needed a replacement spool holder and the screenshot told me the orientation and where the screws went, which the bare model file alone wouldn't have. Takes an extra minute per design and I've never regretted it.
