Support

Need help opening a drawing, working with layers, or managing Caddis Cloud? Email caddissupport@gmail.com with your browser or device, the file format, and a short description of the issue.

Mobile format limits: DWG covers selected R2004 and R2010–R2018 model-space geometry. STEP/STP, IFC, SLDPRT, and SLDASM cover documented geometry/display-mesh subsets rather than every file or source feature. The mobile grid is visual; snapping targets supported geometry.

Our local-first promise

Cloud sync, source uploads, and share links are opt-in, per project. A local session is never turned into a cloud project unless you choose to save it.

Email caddissupport@gmail.com and we'll get back to you.
