2018 — Allplan

If you need to cite the new features of the software:

Allplan 2018 significantly improved its Open BIM capabilities. In a collaborative industry where different stakeholders use different software, interoperability is key.

Allplan 2018 introduced important BIM-focused improvements for its time; users working on legacy projects or in firms standardized on that release will find it capable for architecture and structural workflows, though newer Allplan releases add further BIM, cloud-collaboration, and performance enhancements. allplan 2018

Allplan 2018 wasn't just a bug-fix patch; it introduced significant features that changed daily workflows.

While other software required complex coding, Allplan 2018 introduced Visual Python to a wider audience. You could drag and drop nodes to create parametric staircases, railings, or facades. It lowered the barrier to entry for computational design for the average civil engineer. (Remember to specify which comparison you want if so

Back in 2018, the industry was still arguing over whether you had to be "100% BIM or nothing." Allplan 2018 cleverly refused to pick a side. It allowed users to work with 2D elements, 3D solids, and intelligent BIM components all within the same project.

For firms transitioning from legacy AutoCAD workflows, this was a lifesaver. You didn’t have to model a door handle to get a permit; you could draft in 2D where it was faster and model in 3D where it mattered.

Allplan 2018 included a dedicated toolset for facade modeling and highrise structures. The "Twin Towers" functionality allowed users to create parametric storeys.

Allplan 2018 overhauled how non-geometric data attaches to objects:
