I'm a civil engineer with experience of over 7 years as a design and site engineer. I can also provide services of drafting and detailing and have fluency in both 2D/3D, primarily using AutoCAD 2013.
Other software that I use are Revit Structure, Revit Architecture and use Tekla for BIM works.
As a freelance I have been working on architecture projects mostly, and have acquired the required skills of 3d Max.
Besides that I have experience of working with an estimation team, and use Bluebeam and QSCad for the take-off and BOQ prepartions.
