New Features

  • Resizable 3D viewer — The 3D view panel can now be resized, giving you more room to inspect models or more space for the conversation alongside it.

  • Live design steps during CAD generation — While Leo is building a part or assembly, you'll now see each step narrated in real time so you can follow along as it works.

  • Confirmation before resuming old CAD builds — If a CAD generation was interrupted a while back, Leo will now ask before picking it up again rather than resuming automatically.

  • Library documents available as context — Leo can now draw on documents you've synced in your library when answering questions or generating designs.

  • Library file search by folder path — You can now search your synced files using folder paths, making it easier to locate files in nested directories.

  • Organization name collected during plan upgrade — When upgrading your plan, Leo now prompts for your organization name as part of the checkout flow.

Bug Fixes

  • Upgrade buttons now open the right page — Clicking an upgrade prompt could land on a broken page; it now opens the correct pricing sheet every time.

  • Session titles preserved when you reply — When the assistant named a conversation, typing a reply could overwrite that title — this is now fixed.

  • 3D viewer reload always accessible — If the 3D viewer got stuck, the Reload button could become unreachable. A confirmation prompt now ensures you can always reach it.

  • Mobile: no unintended text selection on documents — Tapping the document area on mobile could accidentally trigger text selection; this has been corrected.

  • Clear error when an Onshape link is no longer accessible — Broken or expired Onshape links now show a descriptive error instead of a silent failure.

  • Upgrading with a different billing currency now works — Users whose billing currency differed from their account's base currency could get blocked at upgrade; Leo now routes them correctly to complete the purchase.
