Most of the additional markups have to do with showing layers of the wall/flooring systems. As well as being able to dimension properly to those layers. Line weights and Hatching are also important to this process so that the drawings are readable, I’m currently working on a construction set now for a project, would it be helpful if I sent that along to you after completion? I’d love to help in any way I can to develop the drawing functionality in Shapr, It is a truly great product to design in, and the more functionality (thoughtfully integrated into the app) for documentation the better! Sorry for the initial delay getting back to you, things got hectic, but I really appreciate your responsiveness and the whole Shapr3D team! It has been great to see this app develop and I’m excited for its future,
