I've ported the Rebar Configurator inside Lapin. And went 3D with it..

3D views - Sections in 3D: right-click a section in the browser to see the model cut by its plane and depth. The section's fills, annotations (dimensions, level marks, tags, texts) and lines, with their pen weights and dash patterns, are shown on the cut. An elevation turns the camera. - Cut elements read as solids: each cut layer is closed by a cap in its own material. - Section box (View → Section box, BX): - handles on its faces, Fit and Cut at plan; - it can be turned about the vertical, or aligned to the selected element; - saved 3D views keep it; - its cuts can show the section fills and hatches, as on a sheet. - Storeys shown in 3D views (report #29): every storey, the ticked ones, the active one only, or the active one and those below. You can also cut the model 1.20 m above the highest storey shown. - Layers in 3D views: every layer, without finishes, or the cores only. A 3D view has its own discipline and style, like a drawing. - Walk mode: right-click in a plan to walk into a room at eye height (WASD, drag to look, Esc to leave). - Walls, columns, furniture and closed windows stop you. Doors let you through. - You walk up and down stairs and ramps, and fall off edges. - Space jumps; F flies through everything. - Export 3D can export the model as the view shows it: storeys, layers, cuts and hidden elements included. - The project's 3D view is now simply named 3D. A project opens on the ground floor plan, with the 3D in a tab beside it. Working together (new) - File → Share session… shares the open project through an invitation link or code. Guests are editors or viewers. - Join session… from the start screen or the File menu. A link also opens the web version as the host's guest. - Each participant undoes only their own edits. - Participants are shown in the top bar, with their cursors and selections in plan. - The connection is end-to-end encrypted. MEP (new, free) - An open MEP module in the free edition:

I've created a live link where you can test the new clasical BIM modeler I've distiled from BubbleBIM on top of Ifc-Lite. https://lapinbim.vercel.app/ Still early development, and any sugestions and bugg reports are wellcomed. Lapin Lapin is a BIM application for modelling and documentation in the browser, built on the open-source IFClite toolkit. It opens, models, draws and documents IFC files entirely on the user's computer: there is nothing to install, and the models are never sent to a server for processing. Models and viewing - Opens IFC2X3, IFC4 and IFC4X3 files, as well as IFC5 (IFCX). Several models can be combined in one project. - Each model is either: - native: editable and saved inside the project; - linked: a reference used for coordination, which is never modified. - Loads files from disk or from connected cloud storage and common data environments. - A fast WebGPU 3D viewer: - orbit, walk and section planes; - measuring; - isolate, hide and filter by class, type, storey or material; - search, spatial tree and properties; - georeferencing. - Analysis tools: - IDS validation, BCF issues and clash detection; - model comparison; - entity lists and quantities, and charts bound to the model; - 5D cost and a construction schedule (Gantt); - scripts and node-based flows. - Project, views and sheets - Project navigator: levels, floor plans, sections, elevations, 3D views, schedules, road drawings, sheets and models. Each can be created, renamed, duplicated or deleted. - Every 2D view has: - a work plane; - a cut plane (1.2 m by default on plans); - a view depth. - Visibility / Graphics per view: - which categories show; - their line colour and weight; - their cut fill and cut hatch. - Building materials table: - each IFC material gets its cut hatch, fill and pen; - layered walls and slabs are hatched layer by layer; - the bands of the same material on neighbouring walls merge; - layers thinner than 2 mm (vapour barriers, membranes) are drawn as a heavy dashed line.

Imagine a Revit/ArchiCad/Civil3D like software, built on top of IFC-Lite, that is a native IFC modeler, documentation and drawings from viewport on layouts generator. Curated for BIM acuracy by none other than Petru Conduraru- the OpenBIM Voice. The UI/UX of the software being verry familiar. Any toughts?

At the below link you can create a free account to beta-test the Rebar config app that is also planed to be part of the BubbleBIM drawing engine, Create an account with a user name and a password. I will aprove it. You can start playing around. Any negative feedback will be greatly apreciated. https://rebar.ciuntucbimstudio.ro/ Please write here if you made an account, in case I miss it.
