The Challenge
Fitting Revit floor slabs to irregular terrain is a slow, manual process. Engineers must individually adjust slab shape vertices to match the toposolid surface, pick the right elevation offsets, and handle floors sitting below ground — a workflow that scales poorly across large sites with dozens of sloped floors and leads to missed points, mismatched elevations, and constant back-and-forth between disciplines. Our Solution
Our Solution
TopoFit automates the entire floor-to-toposolid conforming workflow. Select your floors and toposolid, choose your meshing strategy, and let the plugin subdivide, project, and adjust each slab in one batch operation. It intelligently raises any floor sitting below the terrain before projecting, applies your chosen offset, tracks real-time progress, and resets are just as easy — giving teams full control over the topographic fitting process without any manual vertex editing.
Multi-Floor Batch Processing
Select any number of floors at once and conform them all to the toposolid in a single run — real-time progress tracking keeps you informed throughout.
4 Meshing Strategies
Choose from SubD Vertices, Mesh, Perimeter Division, or Inner Vertices — each tailored to different floor shapes, terrain complexity, and performance needs.
Auto Floor Elevation Correction
Detects floors sitting below the toposolid surface and automatically raises their elevation before projection — no invalid geometry, no manual pre-checks required.
Subdivide & Project in One Step
Combine floor subdivision and toposolid projection into a single operation, or run them independently — giving full flexibility over how and when each floor is updated.
Advanced Parameter Control
Fine-tune mesh resolution, perimeter division length (m), vertical offset (mm), and face-up threshold through a dedicated advanced settings panel.
Floor Shape Reset
Instantly revert any floor's slab shape back to its original flat state — select multiple floors and reset them all in one action without undoing other model changes.
Projection-Only Mode
Project already-subdivided floors directly onto the toposolid without re-meshing — ideal for updating projections after the terrain or floor boundary has changed.
In-Viewport Element Selection
Pick floors and toposolids interactively from the Revit viewport, with live counts displayed in the UI and one-click highlighting of current selections.
