Name the Best 3D Software & the Best 2D Software,in the area of Construction Engineering.?

CAD

If you are looking to make a quick sketch without going into too much details, Google Sketchup is the best option. Though it does not provide the complete control over the design as AutoCad and Revit, it still gives you a good picture to your design

For3D designing my choice is Revit 

AUTO CAD

the Best3D Software solidwork & the Best2d autocad

the best3d software and2d software  in my opinion is revit structure is the best for you becuse it's handel3d and2d in the same time 

If you don't need much drawing details, just need a quick3D sketch, then go for "Crystal3D Impact" software. This is awsome for friendly features.

REVIT is the best for3D

Ofcourse REVIT Architecture & Structure in The Best3D &2D Software in Constuction Field nowadays 

For Buiding Modeling and Designing Purposes ETABS Will Be Good Enough And for Other Structure, Sap Is Most Popular!
