Since I am stopping work on this project, I released the source code as-is; it might help the community. It’s vibe coding, but I put time and my ideas into this
Building elements: walls, curtain walls, doors, windows, columns, foundations, beams, slabs, grids, stairs, roofs, railings, louvers, ramps, skylights, dormers, and molding.
- Site objects: site assets such as planting and outdoor fixtures.
- Drawing and editing: place objects with point, line, path, rectangle, and direction-based drawing modes; edit selected Draupr objects; and use wall, roof, alignment, trim/extend, split, and other geometry tools.
- Materials: browse in-model and renderer-catalog materials, access online PBR materials, adjust material properties and texture scale, and assign materials to objects or parts.
- Assets: save and reuse library objects, presets, and Smart Proxy records with categories and metadata.
- Lighting: author and edit Studio lights, import IES profiles, and connect lighting data to the renderer.
- Project tools: manage levels, schedules, and quantity reports, BIM/project metadata, site review, model health, and settings.
The renderer uses Babylon.js and Blender Cycles as the source. You can use, distribute, and modify the source code, but you don’t have my permission to sell 
it.(GPL licence)
