Design CAD - create and edit DWG/DXF/CTM drawing files

Design CAD is a full CAD application that let you make a lot of things in 2D directly in your iOS device.
It is for everybody interested in 2D CAD as professionals, sketchers, architects, engineers, designers, students and more.
Runs on iPad and iPhone.
Surfaces support and 3d formats like STL, OBJ, DXF and native 3DQ with textures.
You can use the Desktop version(Mac/Windows/Linux) to print your drawings.

- Complete-featured 2D mobile CAD solution, draw with ease and precision. Using our innovative angle-distance polar coordinates method, the multitouch screen of your device is now the fastest and more accurate way to draw anything technical on the go (from building silhouettes to mechanical details) and review/query/edit your drawings right where you need them, on the worksite.
- No internet connection required, you can create new drawings right from your device with desktop-class tools.
- When you are on the go, Design CAD will give you the details and flexibility paper won't. You can query, edit and add geometry. With this new release you have unprecedented power on your hands: you can insert objects (like furniture, appliances, parts, etc), dimensions, text, hatches…a lot of features that will make you save a lot of time and increase your productivity.
- Native DWG/DXF file support, now you can open and save your work on the same format you use on your desktop computer, this bridges your office to your site, you will always have your drawings with you when you really need them.
