Our Product

GroupDraw is a web platform specifically optimized for the communication on and around technical drawings, construction plans and blueprints. It allows you to replace all emails regarding your drawings, CAD files and visual files with a centralized tool that can be accessed with any PC and Mac (no installation required).

The key of GroupDraw is that all the parties can communicate on the same drawing at the same time without the need of any expert skills.

Furthermore, we track all changes and discussions which allows you to find all communication easily if questions are raised in a later stage of the project.
