Planix
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 engineering pipeline adds country-aware preliminary structural defaults, a bill of quantities, a cost estimate, and engineering notes intended for licensed-engineer review. Users can inspect walls and openings in a browser-based 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 in its guide. Revit and SketchUp support is described as beta. The free plan allows 10 plan generations a month and requires no credit card. Planix describes its outputs as concept-to-preliminary grade, requiring licensed-engineer review before construction use. Connect does not yet support structural drawings inside AutoCAD or Revit, mixed-use buildings, or irregular plots.
For and against
For
- Generates dimensioned 2D plans and an interactive 3D model.
- Solver places walls, rooms, and columns mathematically.
- Analyze accepts common document, drawing, and data formats.
- Free plan allows 10 generations a month.
Against
- Outputs require licensed-engineer review before construction use.
- Connect lacks support for mixed-use buildings and irregular plots.
- Revit and SketchUp support is described as beta.
The verdict
Planix combines early floor-plan generation, 3D inspection, and preliminary engineering outputs. Its stated engineering limits and Connect scope restrictions matter for teams considering it for project work.
Who it suits
Planix is aimed at civil and structural engineers, architects, builders, and design-build firms working on preliminary layouts, massing, and rough quantities. It suits users who need early design outputs and can arrange licensed-engineer review before construction.
