In 2013, most BIM tools forced you into a single "master model." Allplan 2013 introduced a more flexible reference view system. You could work on a detail section while the 3D model updated in the background—without crashing or corrupting the file. For large infrastructure projects, this was a game-changer.
Allplan 2013 was designed to bridge the gap between traditional 2D CAD and comprehensive 3D BIM workflows. Its most impactful enhancements included:
Jump to today (2026). Allplan has evolved into a cloud-connected BIM powerhouse. But open an old .NDW file from 2013, and you’ll notice something remarkable: . Unlike some competitors that broke backward compatibility every few years, Nemetschek’s 2013 release respected the long lifecycle of infrastructure projects (often 10–20 years).
It offered sophisticated 3D solid and surface modeling tools capable of handling complex organic forms.
