Fully detailed 3D modelling of precast concrete structures has never been easier with new automated design tools from Allplan. Automated Python Parts (APPs) build on Allplan’s support of the precast concrete industry with new tools that streamline the design and detailing process, particularly for buried structures and buildings. APPs are customizable 3D parametric models that significantly reduce design time. With APPs, precast drawings and documentation can be produced easily and accurately in a fraction of the time compared with 2D drawing methods, enhancing both productivity and efficiency.
