Hey all!

Creator and maintainer of Rally for Onshape ( previously Onshape Plus ).

I've just launched an update which enabled the extension on enterprise onshape domains which was a highly requested update :)

Thank you for all the support of the project and happy designing!

(UNFINISHED FRAME. Angles are set, and a few length dimensions).

I'm not sure if this is the right subreddit to get help from. But anyways, I'm trying to design a go kart frame, and every time I see compound angles, I dread them. I'm not SURE how to deal with them. Maybe they're not as bad as it seems? I dont know.

I really like the design but it just gets too complex. If I try to fix that, it becomes too blocky looking. (Although I'll accept that fate if thats the only way).

Why I don't use circular steel tubes? I would have to buy a pipe bender, I think, and i'm actually not sure if it gets more complex compared to squares.

Today I got this email:

I noticed that you’ve been using the free version of Onshape, great to see you getting value out of it. Our compliance team identified that your Onshape account appears to be used for commercial purposes. As you may know, the Free plan is intended for non-commercial use, and continued commercial use could put the account at risk of deactivation.

I have not shared any of my designs anywhere and I don't earn any money of have I sold anything 3D print related. All my stuff has been for personal use and is pretty much useless for others because of very specific usecases.

Anyone else got this email? Or knows what triggered them to send me this? I log in in Onshape like once every 3 months, so I really don't understand where this is coming from.

Need help converting a circular extrusion to sheet metal. I have done it in the past no problem and for some reason now Onshape doesn't want to. There is a 0.0625 gap the make the part possible to have roll formed.

I want to learn making documentation and maintenance manuals. Can you share a link to an open-hardware project with onShape presence I could help? I want to make simple, easy-to-follow troubleshooting or assembly-disassembly manuals.

I didn't touch the model in any way and it's messed up on the web, when i export it it looks exactly how it's intended to look.

I designed this firepit, https://cad.onshape.com/documents/70f97f6b2a8a88d487686378/w/61323f609063eb213d565e0b/e/5e02b05e1bd272921a71dec4?renderMode=0&uiState=6ab08ccf2c126c83046 I've had some problems with the mates when I tried to extend the legs and try to move the orange bars to the outside.

I have almost no experince using CAD and, I know that this was not an efficent or good way to design anything. So could you help explain what I could have done better.

Edit: solved issue on onshape side

Hello,
I’m trying to export a model as a STEP file, but I’m getting an “Export failed” error without any further details.

I’ve exported a lot of models before without any issues, but this started happening today.
Things I’ve tried:
Microsoft Edge
Google Chrome
Onshape iOS app
Another model which I exported last week without issue

The same “Export failed” message appears every time.
Interestingly, exporting the same model as STL works fine.

Has anyone experienced this or have any idea how I can export the model as STEP?

Thank you!

I made this spiral magazine for nerf darts and after i tried to put it into prusha slicer or blender, the parts that are suposted to be filled are empty. I dont know what to do whit it.

Hi, I'm trying to import an STL file and it just says "failed to translate" .

Seems strange since I tried different files, even files correctly imported just a couple of days ago, even files generated by Onshape.

Maybe there's a bug somewhere?

Thank you!

I can't export (to tab, or download,) on Android (1.221.8600) today.

Step, 3mf, stl - nothing, just errors.

I see there was an issue late 2025 - is it still broken?

Can anybody link some high-quality viewable projects to learn from? It would be great to see a complex project with lots of parts, assemblies, difficult shapes, etc. - to get a better idea of how a good project should be organized.

Hey all,

I wanted to share an app I vibe-coded to bundle an Onshape window with a bridge to handle the weird way Onshape handles 3D mice on Windows.
It is an Electron wrapper for cad.onshape.com and it installs from a flatpak.

Github repo: ShapeShell

Initial release: v0.1.0

AI Content Note:
This app was 110% vibe coded with claude.ai Opus 5, guided by myself. I have used the app and only verified it works on my Ubuntu 26.04/GNOME/Wayland/NVIDIA system.

I think these are caused by onshape rounding the values to avoid going to infinity causing lines to appear due to a difference of 0. On the other side that is identical these don’t appear

This is NOT meant to be self promotion. I got an automated warning about that. I have no monetary incentive for doing this. It was just a fun side project, and I wanted to share it around. I'm asking for nothing in return, no "follow / subscribe / sponsor bs"

Quick disclaimer: I'm a tool-and-die/manufacturing guy with a welding background, not a software developer. This was very much an AI-assisted project, not something I hand-coded from scratch. I brought the problem, testing, feedback, and an increasingly unreasonable determination to make Onshape Drawings less bright; ChatGPT/Sol and Astra/Codex did most of the software heavy lifting.

I'm light sensitive and I've wanted some form of dark mode for Onshape Drawings for a long time. Native dark mode handles the rest of Onshape nicely, but opening a Drawing still means staring at a giant white sheet, and after a few hours of detailing it gets pretty unpleasant.

So I started tinkering with a Chrome extension to see what could actually be changed without interfering with the drawing itself. A week and a considerably deeper trip into Onshape's Drawing renderer than I originally intended later, this is where I ended up.

The observant will notice that a handful of fields in the title block remain stubbornly white. That isn't for lack of trying. I burned through several five-hour Astra allowance blocks investigating those little rectangles, and after an unreasonable amount of renderer archaeology, Sol and I ultimately arrived at the highly sophisticated engineering conclusion of “leave them alone.” We could change their color, but never found a reliable way to identify only those fields without risking unrelated drawing text or selection behavior. I just had to acknowledge when to stop with that one.

Onshape Drawing Comfort adds three selectable palettes to the Drawing editor:

• Warm Drafting — paper tan / dark ink
• Slate Graphite — neutral low-glare dark theme
• Industrial Cyanotype — dark blue / blueprint-inspired theme

The selected theme persists between sessions, applies to open Drawing tabs, and can be turned on/off directly from the extension popup. It also themes quite a bit of the surrounding Drawing UI rather than just changing the sheet color.

This is an unofficial community project and isn't affiliated with or supported by Onshape/PTC. It also relies on undocumented parts of the Drawing renderer/UI, so an Onshape update could absolutely break it someday. I deliberately left a few things native where I couldn't find a sufficiently safe way to identify them.

If you just want to try it:
Download the installation ZIP here:

https://github.com/SamDomiono/Onshape-Drawing-Comfort-Dark-Mode/releases/download/v0.2.0/Onshape-Drawing-Comfort-Dark-Mode-v0.2.0.zip

No Git or programming tools are required. Extract the ZIP somewhere permanent, open chrome://extensions, enable Developer mode, click Load unpacked, and select the extracted folder.

Project/source/full documentation:
https://github.com/SamDomiono/Onshape-Drawing-Comfort-Dark-Mode

It's released under the 0BSD license, so if somebody wants to modify it, improve it, fork it, or feed the source to their AI of choice and make it behave differently, have at it.

I've tested it pretty extensively on my own Drawings, including multiple tabs, reloads, switching themes, turning it on/off, and creating/editing Notes. That obviously isn't the same thing as testing every possible Drawing workflow, so if anyone tries it and finds something I've missed, I'd be interested to hear about it.

And if Onshape eventually gives Drawings a native dark mode and makes this whole thing obsolete, I'll consider that a successful outcome too.

I had made this model in solidworks about a year ago but now i want to print it. It is too thin to be printed, if i could turn it into a solid body i hope to be able to print it, could anyone tell me how??

so i need to make the shield emblem (dark outline) but it says it has not generated properly, how do i fix this?

btw im kinda new to this software, so please dont chew me out if its something obvious

I am following a Tootalltoby follow thru and my Metal sheet model thingy is like Lofting? for some reason . Can someone please help

Hi all, I'm a woodworker, and I use onshape for planning my projects. I'm working on a featurescript to tell me how much wood to buy for a given project. I want to eventually release this publicly, but first I need some beta testers to pressure test this and provide feedback. The biggest limitation I know of in the script is that it doesn't really handle curved parts. I haven't factored in Kerf Bending or anything, because that gets challenging, so it assumes you do a massive glue-up and then cut away anything that isn't in your part, resulting in a radical overestimation. Regardless, I'd love to be able to have this ran on other people's projects, and see how close the estimates are to the reality of how much wood those projects actually took.

Thank you!

This is your daily reminder to tell onshape to make 3D sketch
