Pro/DESKTOP (commonly referred to as Pro/D) is a Computer-aided design (CAD) program from Parametric Technology Corporation (PTC), that allows users to design and model in 3D and create 2D drawings. It can transfer a 3D design into a 2D engineering drawing format and also create photo-realistic views using Album Views. It is part-compatible with Pro/ENGINEER, and uses the Granite kernel, but otherwise is a freestanding CAD system.
