• Are you using app.zoo.dev or the downloaded desktop app?
• What OS are you on?

As a first step, could you try using a different auth method (you can choose from Google, GitHub, Discord, etc).

If that doesn’t work, could you please open up the Chrome Console and let us know if there’s any errors? You can do this in your web browser by going to the vertical dots in the top-right and clicking “More tools” > “Developer tools”. Or in the desktop app on MacOS, use Cmd+Option+i (on MacOS) or Ctrl+shift+i (Windows, Linux).

If you capture a full .HAR archive using the Devtools (see these instructions: https://support.threatdown.com/hc/en-us/articles/4770107420819-Collect-HAR-file-with-Google-Chrome) you can email it to me at [email protected].

After work with AI i got perfect results but I cant export them to STL.

Here is recoreded video with problem: https://zawojit.fra1.cdn.digitaloceanspaces.com/z4prints-website/Nagranie%20z%20ekranu%202026-03-13%20o%2022.45.53.mov

But in words. I try to export and get these wierd error:

Just to add to what Austin has already said, operating directly on the imported model via KCL will be limited to operations like subtract, intersect, union. A possible route that would allow natural language and modification of the model would be to ask Zookeeper to recreate the step file in KCL. From there you (or Zookeeper) can iterate on the model using the full suite of KCL commands. We’re working on improving the capabilities of Zookeeper working with various formats like images/pdfs/dxfs/ and CAD interop formats.

One thing to note, Zookeeper may not be able to do a perfect 1:1 recreation of your step file, so you’ll want to ensure the KCL recreation and original step file match first. This can be done in a number of ways, visual inspection, checking various physical analyses like surface area and volume match.

Thanks,

Thanks for your question. Talking to some other team members, it sounds like imported geometry can be used for some operations (like the boolean subtract, intersect, union, etc.) but not edited directly as KCL, which would also mean it can’t be modified directly by Zookeeper. It looks like our documentation could be improved here to explain the limitations and I’ll also check with the ML team to see if we have anything on the roadmap to allow this kind of interaction in the future.

For the import error, I was able to reproduce it with a simple part I made so I raised a bug with the file format team. It might also be part specific, so if you’d like us to investigate your part directly, you could also share it with us. The error message itself isn’t very helpful as there are many reasons import could fail so that is something we also will address.

Thanks for being part of our community and we hope to continue to help you find value in our product and really appreciate your feedback as we work to quickly improve our offering.

Thanks,
Austin

I want to know if there is a way to import custom .stp files and then edit them using natural language text and export back.

I tried Zoo Design Studio, I am able to do this for existing samples provided but not on my .stp files. When I import my custom .stp file I get some unknown error. (Image Attached)

Ideally I want to create a workflow, where I will be using your APIs to upload a .stp file, edit it using natural language prompts and export back. Is this possible, right now with your APIs? I can see the iterate/modify design api in ML part of your docs but not to iterate on an existing CAD.
Can you help me with this as well?

I assume you’re on Windows based on the filepicker UI in the screenshot, but which version of Windows? Also which version of the app is this?

Hi,

Please cancel my Pro subscription ASAP and consider a refund.

Email: [[email protected]]
Reason: Upgraded to Pro but found it hard to use → barely/no usage.

Hoping for full or pro-rata refund since minimal use.
Please delete/remove all saved credit card or payment method details from my Zoo.dev account.
Thanks!

I put in a fix last week for this. The engine no longer errors on this command, and all the edges you requested are filleted. Please give it another shot if you’d like. Note that the locations where the fillets interact with each other are still a bit weird in your example; that’s an active area of development, but hopefully this fix is helpful for your project.

Where have you tried uploading the JPEG file?

As for your blocked status, I’ve logged this bug in our tracking system to investigate it and fix it if you ended up needing to refresh to see your upgrade. Let me know if I’m on the right track there!

Then I got confused by how our usage tracking works while looking through our backend, but you should now only get billed for your unlimited subscription, not individual usage charges. I’m just confirming that with our payments folks.

So I actually have an action item as a developer: we need to make sure you see your upgraded status right away in the app. I’m going to try to recreate your situation and fix that stale blocked status if that’s the case. Always love it when the issue ends up being something I can fix in my team’s code.

I’m talking with our payments folks to help me cancel your outstanding balance, and help them investigate the issue with not canceling any outstanding balance from the same billing period that a user might have from before they switched to Pro.

Thanks for your patience, I want to get you back up and modeling!

In the meantime I’ve got two questions:

1. Were you in the Desktop or Web app?
2. When you say your usage got cut off, I just want to clarify that you mean the Zookeeper AI pane here in the app showing a message that said you were blocked until you upgrade?
   
   

So glad to hear you’re enjoying using the app! We do deduct based on time - each second of processing uses $0.0083. Usage you can view on your account’s billing page.

Currently, you can’t see your balance update in the app live, it only updates after the connection is closed. Our team is aware this is an issue and is working on getting this changed in the future and I’ve flagged this again with your comments.

Let me know if you need anything else, thanks!

Best,
Persis (Zoo Website Developer)

I recently signed up for Zoo and have found the app to be amazing. I’m reaching out regarding an issue with my Zoo balance. I used the text‑to‑design feature online, but the balance did not change at that time. I stepped out of the office for a few hours and left the part open online, and when I returned, the balance was at zero.

Could you please clarify how the balance is used? Is it deducted per text, per design, or based on time? Additionally, is there a way to view the balance history or usage record?

Thank you for your help.

We have an github issue for this Panes that can be moved and undocked · Issue #8061 · KittyCAD/modeling-app · GitHub

I’ll help troubleshoot the issue,

• Are you using the website at https://app.zoo.dev/ ?
• Are you using the desktop application? On which version?
• If you click reconnect, does it reconnect? or stay disconnected?
• Have you connected before or you have never connected to the stream?

There are logs locally stored in the application for connection issues. I can provide a better interface to access and send us these logs to debug and troubleshoot.

I have done your suggestion to allow outbound TCP port 443 and UDP port 3478 to Zoo but still not working !!!

thanks for reporting this. I’ve just found that the button stays disabled until you select one of the options from the address dropdown.

Hope this helps — I’ll report this bug in the meantime.

Unfortunately the last three days I cannot add a payment method. I add my credit card and all the details but the add payment button remains dark blue and inactive. Is there any additional step I miss? Can you please help me?

Thank you in advance.

• We just completed our SOC2 Type II audit which you can checkout here: https://trust.zoo.dev/
• Additionally, we perform third-party source code audits, which we will also publish at trust.zoo.dev.
• We also got a program for coordinated vulnerability disclosure described in point 1 here: Security | Zoo

We go above and beyond and proactively secure the Zoo platform.
