Calq is a BIM modeller that runs in a browser tab. You model walls, floors, roofs, stairs and rooms, and the plans, sections, elevations and sheets come from the same model, drawn to scale with their dimensions, keys and title blocks. It is free to draw without an account; saving makes a free account that imports IFC and CAD and exports IFC, DXF, COBie, gbXML and PDF sheet sets. The AI tools are on the paid plans, and Pro starts with a 14-day trial.
