I am an architect in Vietnam. I am an expert on BIM 3D. I have an application that runs on the Revit software. It can design 3D very quickly and with high accuracy. It greatly saves time and manpower. You can see the automated 3d design preview at the following link: https://youtu.be/VYL-vD5wuC4. See more at my website: www.vietbim.com.
