2.4 /5 composite score
C1 4/5 reflects transparent, disclosed pricing ($2,585 one-time perpetual license OR $235/month subscription; no subscription lock-in for perpetual option); C2 1/5 reflects GUI-only interface with no documented API, CLI, or scripting access (RF2); C3 3/5 reflects self-serve adoption pathway (30-year established brand with learning materials), though vendor-led implementation may be recommended for complex workflows; C4 2/5 reflects DWG and DXF export support but limited interoperability with modern BIM ecosystems (no IFC, no Revit native exchange); C5 2/5 reflects limited integrations (SketchUp, Lumion noted; Revit not documented as native integration). Firm-size fit is solo to small-team.

Alternatives in BIM Authoring
Free, open-source native IFC authoring add-on for Blender (formerly named BlenderBIM, renamed Bonsai in 2024). Built on the IfcOpenShell library, it lets users view, author, and enrich IFC BIM models directly inside Blender, covering modeling, drawing generation, and openBIM workflows. Distinct from the catalog's unrelated existing "Bonsai" entry (hellobonsai.com, a freelancer invoicing SaaS).
4.6/5
A full desktop BIM authoring platform from Graphisoft built specifically for architects to model buildings and produce coordinated drawings and documentation.
4.2/5
A combined CAD-and-BIM design platform from Vectorworks (Nemetschek Group) aimed at architects who want flexible modeling plus documentation in one tool.
4.0/5
A DWG-native BIM tool (from Bricsys, now under Octave) that adds rule-based BIM modeling and auto-classification on top of a familiar AutoCAD-like drafting environment.
