Please note that these pre-release notes are subject to change.
CET 17.5 Major: November 19, 2026
All Editions
News & Changes
2D / 3D Graphics
Improved spacing for 3D Text in the 3D view. Existing drawings that contain 3D Text will automatically use the updated spacing when opened in CET 17.5, which makes the text layout look more consistent and easier to read.
AI Photo
- AI Photo Moves into Photo Lab
AI Photo is now part of CET Core and available directly in Photo Lab, with no separate AI Photo license required. Generated AI photos are integrated into the photo series, where you can access and manage them using the same workflow as other rendered images in CET.
Tokens are still required to generate AI photos.
CAD
- Added a new option in the ‘CAD Export’ dialogue to use an improved export method for imported DWG files.
CRM Connect
- The CRM Connect Extension is slated to retire with CET 18.0 in May 2027. A notification has been added to the CRM Connect tab with this information. Please note that you do not need to uninstall CRM Connect manually; CET will automatically remove it for you.
Catalogue Creator
- Improved catalogue propagation filter options by introducing a new "Same Part Number" filter for applying properties only to products with the same part number. The existing filter has been renamed to "Same Product Family" to better reflect its behavior.

Catalogue Downloader
- Users are now defaulted to the new Catalogue Downloader. To support the transition ahead of the legacy downloader's retirement in CET 18.0 (May 2027), a notification has been added to the legacy downloader. Users can continue switching between the legacy and new downloaders from Control Panel until CET 18.0, when the legacy downloader will be retired.
- Improved Catalogue Downloader reliability by preserving ongoing and queued downloads across deadlock recoveries, reducing unnecessary reprocessing and helping updates complete more efficiently.
Drawing Tools
- Added the Dimension Tool to the 3D View toolbar for quick and direct access while working in 3D.
