Using Mech-Q (AutoCAD add-on) we can create a 3D sloped beam. Video explains how to rotate the UCS (user coordinate system) and use polar tracking to achieve a snap angle for the slope.
We are also working in AViCAD, which is a AutoCAD Alternative with Mech-Q included. In addition we are using Mech-Q’s Structural module to create the steel beam. for more visit
