Do you need a free software to view drawings?
 

When we want to communicate drawings with colleagues and customers anytime, anywhere, we need a powerful APP that can open files in various formats and support multiple operations and sharing functions.

Tsridiopen can achieve these things，it is supports more than 40 kinds of 3D models and 2D drawings. It is currently available for a limited time free trial.
