Rampe
Create custom ramps from an axis, a longitudinal profile and variable cross-falls on the left and right edge. The tool generates a dynamic reference surface that links to architectural elements such as slabs and walls — ideal for access ramps and underground car parks.

An introduction to creating and editing parametric ramps.
From an axis to a 3D ramp
A complete toolset for the parametric modelling of ramps of any shape.
Ramp from an axis
Taking over an axis with lines, arcs and clothoids as the basis for the ramp geometry.
Free longitudinal profile
Freely defining the ramp's longitudinal profile to match the real conditions of the project.
Separate cross-falls
Separate cross-falls and track widths for the left and right edge of the ramp.
Edge axes and offsets
Boundary axes for the ramp edges and offsets along the axis for a precise start and end.
Plan view with data
A plan representation with heights, cross-falls and chainage for documentation.
3D representation
Automatic 3D representation of the ramp as a BRep and 3D surfaces for further processing and visualisation.
Dynamic reference surface
Automatic reference surfaces for architectural elements (slabs, walls) with a uniform subdivision.
Easy editing
Subsequent editing of ramps and automatic clean-up of abandoned reference surfaces.
What it is for
Ramps of any shape with variable gradients — from building access to underground car parks.
Features and examples
Ramp tools and examples from real projects.

Ramp creation

Ramp editing
Subsequent editing of the ramp parameters with automatic updating of the geometry and surfaces.

3D ramp
The ramp represented as a BRep and 3D surfaces, ready for further processing in the model.

Underground car park
A ramp providing access to an underground car park, aligned with slabs and walls.

Access ramp
An access ramp to a building with variable cross-falls along the axis.

Working on reinforcement?
The ALLTO line automates 3D reinforcement in ALLPLAN — slabs, walls, beams, columns, foundations and elevator pits. It is built for structural engineers: parametric PythonParts create the bars, sections and labels, and the quantities come straight out of the model.
