Isnt using Onshape risky?

If I compare some CAD products in regards to usage risk.

  1. Local software with perpetual license (Solidworks) - Its running on your machine without external dependencies and license is valid forever. It will basically work forever unless you do something wrong.
  2. Local software with subscription (Inventor) - Still local and without external dependencies but you have to keep paying for subscription. If you stop paying you cant edit your content. But at least you can still view everything for free locally.
  3. Semi-cloud software with subscription (Fusion) - The software runs locally, but it depends on cloud infrastructure. Similar to group 2. but since content is stored in cloud if cloud servers are down you lose access. You can technically backup/edit locally but its not straightforward. The usage of product is restricted without cloud.
  4. Fully cloud software with subscription (Onshape) - You run it in browser in cloud. Since nothing is local, if cloud is down you cant even run the software. Even if you backup some files locally you are out of luck. You are fully depended on their servers.

And thats why I am asking if Onshape isnt kinda risky. You never know if their cloud servers will stop working. Or maybe they will block your access because of some reason? Maybe some license violation?

You store and manage your valuable product CAD data on foreign servers you dont control. You depend on them that you will always have access which isnt guaranteed. So I wonder, isnt it risky to use fully cloud software like Onshape? Especially if your whole company depends on it?

I’m a beginner and I’ve been working on this assignment for the past four hours and I managed to do everything except the incline outer walls can someone please help me I’m exhausted and sleep deprived 💔

Ps: Thanks yall so so much it was waaay easier than expected I will be having more complex designs in the future what are some advices that yall can give me to get better at it

CustomFeature: WormGear

Hi everyone,

I'm Younseo Lee, a robotics researcher at Seoul National University.

We use Onshape quite a lot in our lab, and I've always wanted to create and share a custom FeatureScript with the community.

Recently, I came across a discussion about the lack of a proper worm gear FeatureScript, so I decided to give it a try (with some help from Claude!).

The result is WormGear, a custom FeatureScript that generates a worm and its matching worm wheel directly in Onshape. And yes, it even supports double worm gear configurations!

The main goal was to make worm gear modeling easier and more accessible. Instead of manually creating helices, tooth profiles, and complicated sweeps, you can generate a complete worm gear set by simply adjusting a few parameters.

Key Features

  • Worm and worm wheel generation with matching tooth geometry.
  • Multiple tooth profiles: ZA, ZN, and ZI.
  • Customizable parameters: Module, number of starts, gear ratio, pressure angle, lead angle, backlash, center distance, and more.
  • Double worm gear option: Two worms on opposite sides of a wheel, allowing both rotational and linear motion.
  • Additional options: Shaft dimensions, hub geometry, initial positioning, and interference checking.

I've also prepared a User Guide with detailed explanations of the parameters and instructions for using the feature, so please take a look if you're interested.

This is my first time sharing a FeatureScript with the Onshape community, so there may still be some things to improve.

I'd really appreciate any feedback, suggestions, or bug reports. And of course, I'd love to see what you create with it! I hope you find it useful for your projects.

Thanks, and happy modeling!

I built an open-source tool that turns part descriptions into editable Onshape feature trees

I built fsgen to generate mechanical parts you can keep editing in Onshape: variables, constrained sketches, extrudes, fillets and patterns.

The demo shows a generated part and its actual feature tree. You can copy the example document and try changing a variable or sketch.

It checks the script and builds supported geometry locally before uploading, so those iterations don’t use Onshape API calls. Native upload needs API keys. There’s also a zero-call manual paste option that creates one parametric custom feature.

Still experimental, with generation tested using Claude. Local feature support is limited. I’d like a few Onshape users to try it on a bracket, mount or enclosure and tell me where it breaks.
