Which program do you prefer to use for architectural design and why?

Revit is the preferred application for Architectural BIM documentation

Revit, its handy and not as rigid as AutoCAD for example. BIM compatible. You are modeling rather than drawing lines. I like it.

Revit is the preferred application for Architectural BIM documentation because of the widely available installed base and trained man power

ArchiCAD Because I'm good use in the design drawings2D &3D and i prefer3ds max for render.

Revit, autocad,3dmax and Vray.

Try Revit Architecture, though few draw backs are there still its worth go with it. simply because it is widely used.

autocad, archicad, sketchup, lumion, photoshope.

REVIT ,3DS MAX AND AUTOCAD MOSTLY
