we tested cadworx on bricscad at the beginning of covid while remote and found that using bricscad remotely via VPN was exponentially slower than using autocad/cadworx. Im not IT so i couldnt tell you how they were both operating through the server. we tested on the same model and tested using only autocad and bricscad made models. all tests showed bricscad was literally 10 times slower. you would sit there twiddling your thumb while bricscad tried to compute view changes or if you tried orbiting your model. this is in any visual style (hidden or wireframe types). bricscad was unusable for us remotely. we tested for a few weeks then dumped it. the VPN/remote slow downs were substantial compared to using autocad. if cadworx end support with autocad we will 100% make the switch to Plant 3D. its cheaper, runs better, has far better support (the Hexagonppm support ticket system is a nightmare for our designers) and its MUCH CHEAPER! ha
