Video coming soonDrainage 3D: from connector to finished 3D network
Place connectors, draw the plumbing line, click Generate 3D – LuaCAD calculates slope, pipe sizes and fittings and builds the network in the system you choose.
Video coming soonFast routing – even in the in-wall carrier
Place fixtures and connectors in the floor plan; the plumbing line leads to the stack. Inside the in-wall carrier you route with dedicated tools: building drain, stack, connectors at the right height.

Generate 3D: slope and sizing, automatically
One click and the sketch becomes the pipe network: slope from your settings, pipe sizes from the calculation, wyes, elbows and offsets from the system catalog. Sizing notes appear in a list – Show takes you straight to the spot.

Standards and systems built in
Sizing follows DIN EN 12056-2 with DIN 1986-100, alternatively SN 592 000 or no standard. Push-fit systems (e.g. PP) and welded systems (PE with electrofusion couplings) are built in – including engagement lengths and weld loss.

Across several levels
LuaCAD divides a stack across several levels into the drawings of each level – the load from above is included. If you move it, LuaCAD asks whether the other levels should follow.

Annotation, spot elevations and lists
LuaCAD annotates pipes with material and diameter, plus slope and invert elevation – the annotation follows the pipe. Parts lists and bills of materials come from the same model, and the 3D network can be passed on as IFC.
