AutoCAD - Draw a 3D stairs from 2D
Download: https://drive.google.com/file/d/1xqin...
One of the best way of creating 3D using AutoCAD is starting from an existing 2D drawing. Once you have top view and elevation view, you don't need dimensions at all to create 3D from them. You just need to snap to the point you need.
For my previous students, I eliminate the need to create boundary polylines first by using UCS - object method instead.
Tips: Look at the AutoCAD command line in case of something that is not clear.
