Autocad is used for interior design standard drawings, and coreldraw is vector drawing design software, which can simply simulate physical effects just like painting. Photoshop is a software for image processing and modification, which can modify bitmaps. 3dmax is used for physical modeling and simulation, which can illuminate, arrange scenes for rendering and simulate three-dimensional effects. Being the same company as Autocad, we can build models in cad and import them into 3d for material addition and rendering. These softwares are used in the design industry.
