The revised geometric logic prevents walls, slabs, and structural steel components from overlapping, boosting overall model quality.

This philosophy — addressing construction realities early in the design process — underpins nearly every major feature introduced in the release. By building detailed, precise models from the outset, teams can avoid costly rework and coordination issues later in the project lifecycle.

The updated IFC4 export engine guarantees precise geometry and metadata transfer, minimizing data loss when collaborating with external engineers using different CAD software.

For road design, Allplan now employs a fully parametric approach. A road model is calculated based on assigned cross-section templates, and all plans and reports can be automatically derived directly from the model. The parametric concept allows the gradient of a road axis to be subsequently changed or the terrain base data to be easily adjusted as the project evolves.
