What it is

Planix turns a plain-English project brief into dimensioned 2D floor plans, an interactive 3D model, and preliminary engineering outputs. A mathematical solver places walls, rooms, and columns. The pipeline supplies country-aware structural defaults, a bill of quantities, a cost estimate, and engineering notes for review by a licensed engineer. Users inspect walls and openings in a browser WebGL viewport and download AutoCAD-compatible DXF and PDF files; listed export formats also include IFC, OBJ, and STL. Planix Analyze accepts IFC, PDF, DXF, Excel, image, CSV, and DWG files for preliminary structural or civil analysis. Planix Connect is a Windows desktop agent for installed AutoCAD, with AutoCAD 2018+ and Revit 2021+ compatibility listed; Revit and SketchUp support is beta. Connect does not yet support structural drawings inside AutoCAD or Revit, mixed-use buildings, or irregular plots. Files use private storage and signed download URLs. The Free plan costs nothing and allows 10 plan generations monthly.
