Please suggest me that which software is suitable/easier for preparing 3D drawing ?

Dear SIR ,

It Depends on the type of Drawing you are tending to make , If it Was :

1- Concrete Structure & Arch. Drawings in Construction Proccess , You can use [ Revit Arch./Struc. ] Software 2- Interior Design Drawings , You can use [3D Max Design ] Software .

Best Regards . 

If you are an architect and not doing complex models then sketchup is the easiest3d tool to use.

I think both of Revit Structure and Architecture can get the job done within a short time, also AutoCAD Structural Detailing is so powerful software to draw a3D Model.

If you want to get an ease access to3d then you can use Google Sketchup, where modeling is very easy for architectural buildings. you can prepare2D drawing in Autocad.

hope this will help you...

You can try Allplan-2013- Engineering version.Its a nemetschek version with low coat. BIM software like Tekla- I feel very nice for3-d concrete and steel detailing.

Solidworks is best and easy too 

Consider SolidWorks, SolidEdge, Catia etc. for3D designs.

Hello Subhashish, try Kubotek KeyCreator .. I think you will find it easy to learn basically because it's not parametric and almost similar to AutoCAD. It also has powerful3D modelling capabilities.

Good luck

i like3d max 

for2d drawing autocad, for3d conceptual massing sketchup....for construction drawing for exterior with3d model revit architecture and for render3ds max importing model from anywhere...though vray makes it easier for sketchup etc.

Revit architecture is able to do it strongly
