Complete 2D/3D design for power, lighting, KNX, data, fire, security, and video systems — built on an IFC reference model with a unified system navigator.

Smart circuit selection, automatic component dimensioning, load calculation from end consumers to main supply, and real-time voltage drop calculation.

Smart multi-storey cable and cable tray design with automatic laying plans, length calculation, shortest-path routing, and load/fill monitoring (IEC 61537).

Integrated lighting calculation (Relux/DIALux), photovoltaic design, standards-compliant security detector planning (VdS 2095), and lightning protection/earthing design. These are also available as standalone DDScad modules in some markets.

Smart clash detection, cross-trade coordination, and automatic model-to-database synchronization for up-to-date diagrams.

Automatic parts lists, cable lists, circuit diagrams, distributor views, patch panel overviews, and system diagrams — with a GMC-I test equipment interface.

Design sanitary, heating, cooling, gas, fire hydrant, and sprinkler systems in one workspace, with intelligent pipe network design and automatic object connection across floors.

Run U-value and heat load calculations per EN 12831-1, with intelligent radiator design that automatically places units by room based on the calculated load.

Automatically dimension and hydraulically balance heating and cooling systems with real-time pressure loss calculation, including underfloor heating field planning per EN 1264.

Design and calculate potable water systems with pressure loss balancing, temperature drop and stagnation analysis in circulation and hot water pipes, plus support for centralized, decentralized, and multi-boiler configurations.

Analyze systems with visualization filters for worst path, velocity, insulation, and diameter, and manage calculated pipe networks efficiently through a comprehensive system navigator.

Design round, oval, and rectangular duct networks — even in combination — with intelligent automatic object connections and storey logic that handles connections through ceilings and floors.

Factor mechanical ventilation, passive pre-heating, and heat recovery directly into heat load calculations per EN 12831, and design controlled ventilation systems in compliance with DIN 1946-6.

Specify and calculate supply and extract air at the individual room level, with automatic adjustment of air terminals based on volumetric flow rate and automatic duct network dimensioning by flow velocity criteria.

Run pressure loss calculations in real time with automatic system balancing, plus configurable velocity and dimensioning limits that inherit across duct segments for consistent, reliable results.

Analyze your system with visualization filters for worst path, velocity, insulation, and diameter, and generate standards-based diagrams (EN 12792) with fully automatic labeling that updates with your calculation results.

Create complete 2D and 3D installation plans covering the full scope of safety engineering — fire, security, and alarm systems, video surveillance, access control, plus data, telephone, nurse call, and intercom systems.

Generate configurable system diagrams automatically for power supply, fire detection, emergency lighting, data network, nurse call, and security systems — no manual diagram building required.

Automatically position smoke detectors in full compliance with VdS 2095, and visualize detection coverage areas for movement and presence detectors — with professional documentation generated alongside.

Design multi-storey cable and trunking systems with automatic length calculation and shortest-path routing to the distribution board, plus automatic cable and cable pull lists and load-capacity monitoring.

Catch design gaps early with control functions that flag objects with missing or interrupted connections, and finish with associative, freely configurable component and cable labeling plus automatic legends for clean, compliant handover.

Plan PV systems in full 2D and 3D across any configuration — rooftop, in-roof, façade, or ground-mounted — using a built-in database of generic mounting systems, with automatic generation of roof layouts, string diagrams, and system schematics.

Show clients exactly what to expect with realistic renderings of sun course and shading throughout the day, plus photorealistic presentations complete with sun animation and video output.

Get accurate performance forecasts using a global climate database covering over 8,000 weather stations, with dynamic yield estimation that accounts for module warming, reactive power, and real self-consumption profiles.

Generate configurable parts lists by title, area, or building, and produce assembly and installation plans in DWG, DXF, or PDF with scaled plotting and printing ready for handover.

Design external lightning protection systems flexibly in both 2D and 3D, using freely definable cross-sections, elevations, and part models tailored to any building geometry.

Apply 2D and 3D lightning balls directly on your 3D building model to run the rolling sphere method, ensuring standard-compliant protection zone coverage from the design stage onward.

Automatically plan mounting and retaining systems alongside assembly and installation drawings — reducing manual layout work while keeping every element standards-compliant.

Generate configurable parts lists by title, area, or building, and produce assembly and installation plans in DWG, DXF, or PDF with scaled plotting and printing ready for handover.
