DWG file guide
What is a DWG file?
A DWG file is a CAD drawing file commonly used for architectural plans, engineering drawings, layouts, and other technical documentation. It can contain geometry, layers, dimensions, annotations, and related drawing data.
No account required for local viewing. Files stay on your device unless you opt into Cloud.How do you open a DWG file?

How to get started
- Open Caddis on the web or iPhone.
- Select the DWG file from your device.
- Review the drawing and verify important information against the authoritative source.
