Hidden Pricing

3.0 /5 composite score

C1 1/5 reflects pricing-wall red flag (RF1): vendor does not publish cost; 60-day free trial available but pricing requires direct contact; C2 4/5 reflects documented COM API with C#, C++, and Python/VBScript support, enabling direct scripting control of Renga models (best agent access among Revit alternatives researched); C4 4/5 reflects comprehensive file-format support (IFC, DWG, DXF, PDF, OBJ, STEP, JT, C3D on export); C5 3/5 reflects integrations with 3DSpaceMouse, Lumion, Blender, 3ds Max, and vendor-published Pilot-ICE BIM collaboration framework. Firm-size fit is small-team to growing.

Alternatives in BIM Authoring

BlenderBIM (Bonsai)

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

Archicad

A full desktop BIM authoring platform from Graphisoft built specifically for architects to model buildings and produce coordinated drawings and documentation.

4.2/5

Vectorworks Architect

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

BricsCAD BIM

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.
