For thirteen years as an AutoCAD Draftsman, AutoCAD from Autodesk is probably the only CAD software that I would say I had used mostly. Although sometimes, I got a chance to use the AutoCAD’s counterpart the Microstation by Bentley. But I only use the microstation rarely, that is why up to now I can’t say I am an advance user of microstation software.

Did you know, that having a knowledge from other CAD software other than AutoCAD makes you more competetive?, comparing to those who only know one software. So that’s why it is recommended that we should atleast know how to use other CAD software. And  how are you going to gained a knowledge on other CAD  software if you don’t own one?, unless if get yourself train in a training center. Well we can always get a free CAD software but as I always said, you can only use it in some period of time, common is 30 days trials.
