For architecture modeling I use Sketchup. This program allows me to perform different tasks of variable complexity and also export useful projections for further work. I also use Rhinoceros for complex geometry modeling and parametric modeling.
My main tool for drawings is Rhinoceros for its great functionality and ability for instant 3D modeling. Also familiar with Autocad.

After exporting images from 3d modeling software I usually use Illustrator for line weight correction. And my main software for collages and color correction without no doubt is Photoshop for its powerful abilities.
For most of my illustrations I use Blender as very powerful rendering tool and perspective program. I also use V-ray for Sketchup for draft renders.

For simple 2D animation I use After Effects, but for complex 3D animation my main tool becomes Blender and After effects is used for color correction mostly. For video and sound editing I use Premier Pro.
