Buy CAD Software – 2D/3D Design & Home Planner Licences

Computer-aided design – CAD for short – is the indispensable basis for professional technical drawings, designs and plans in architecture, engineering, mechanical engineering, electrical engineering and many other technical disciplines. The right CAD software enables precise 2D drafts and complex 3D designs that could never be achieved with this quality and efficiency by hand. At Lizenzindustrie you will find CAD and planning software – from home planners to 2D/3D design – as verified licences – by email, at a price clearly below the regular list price.

What is CAD software?

CAD software (computer-aided design) enables technical drawings and three-dimensional models to be created digitally on a computer. It replaces the traditional drawing board with a precise, powerful digital working environment with decisive advantages:

Precision: CAD works with mathematical accuracy – no blurring or measurement inaccuracies as with hand drawings.
Efficiency: Changes can be made quickly and cleanly at any time – without erasing and redrawing. Repeating elements are created once and used as often as you like.
Standardisation: Templates, symbol libraries and dimension styles make standards-compliant drawings easier.
Collaboration: Digital CAD files can easily be shared with colleagues, customers and manufacturing partners.
3D visualisation: 3D CAD enables realistic visualisations and simulations before actual production.
Interfaces: CAD data can be transferred directly to CNC machines, 3D printers and other manufacturing systems.

2D CAD vs 3D CAD – what do I need?

2D CAD is the digital equivalent of the classic technical drawing – for floor plans, sections, elevations and technical documentation. 2D CAD is sufficient for many applications in architecture and construction, electrical engineering, plant engineering and wherever two-dimensional plans and drawings are enough.

3D CAD enables three-dimensional solid models to be created that can be viewed from any perspective, analysed and used for simulations. 3D CAD is indispensable in mechanical engineering, product design, vehicle construction and wherever spatial geometry, collision checks and realistic visualisations are required.

Modern CAD software usually offers both options – 2D drawings can be derived directly from 3D models.

CAD software for different industries

Architecture and construction: Floor plans, sections, elevations and complete building plans with all standards-compliant representations. BIM-capable CAD software (building information modelling) also enables a complete digital representation of a building over its entire life cycle.

Mechanical engineering and product design: 3D parametric design with assemblies, parts lists and complete manufacturing documentation. Direct connection to CAM systems (computer-aided manufacturing) for CNC production.

Electrical engineering and electronics: Schematics, circuit diagrams, terminal diagrams and control cabinet layouts with a standards-compliant symbol library.

Interior design and furniture design: Room planning, furniture construction and realistic 3D visualisations for customer presentations.

Trades and manufacturing: Technical drawings for woodworking, metalworking and other trades.

Well-known CAD programs on the market

For orientation, here is an overview of widely used professional solutions, not all of which are included in our range:

AutoCAD (Autodesk) – For decades, AutoCAD has been the reference product for technical 2D drawings and 3D designs. DWG – AutoCAD's native file format – is the de facto standard for exchanging technical drawings worldwide. AutoCAD is now only available as a subscription. Autodesk also offers specialised industry versions: AutoCAD Architecture, AutoCAD Electrical, AutoCAD MEP and others.
BricsCAD – BricsCAD is a well-known AutoCAD alternative with DWG compatibility and all the important 2D and 3D CAD functions. The licensing models have changed recently – check with the manufacturer whether the edition you want is offered as a perpetual or subscription licence.
ZWCAD – ZWCAD is another fully DWG-compatible AutoCAD alternative – available as a perpetual licence, with full 2D and 3D CAD functionality. Particularly attractive for budget-conscious users looking for AutoCAD compatibility without subscription costs.
SolidWorks – SolidWorks is a widely used standard for parametric 3D CAD in mechanical engineering and product design – with full assembly modelling, simulation, FEM analysis and seamless integration into manufacturing processes. The professional standard for medium-sized and large industrial companies.
CATIA (Dassault Systèmes) – CATIA is a very comprehensive CAD/CAM/CAE system – used in aerospace, the automotive industry and complex mechanical engineering. An enterprise solution for the highest requirements.
Solid Edge (Siemens) – Solid Edge is Siemens' professional 3D CAD solution for mechanical engineering – with synchronous technology that combines parametric modelling with direct geometry input.
SketchUp – SketchUp is particularly popular in architecture, interior design and furniture design – with an intuitive 3D modelling interface that is also accessible to users without technical training.
DraftSight – DraftSight from Dassault Systèmes is a 2D CAD solution with DWG compatibility (now subscription-based) – particularly suitable for users who mainly create 2D technical drawings.

AutoCAD or an affordable alternative?

AutoCAD is the industry standard – but Autodesk has switched its licensing model entirely to subscriptions, which causes considerable costs over time. For many users, DWG-compatible alternatives such as BricsCAD, ZWCAD or CorelCAD are the more economical solution:

Full DWG compatibility: BricsCAD and ZWCAD open and save DWG files natively – no conversion effort when exchanging data.
Familiar interface: Both alternatives use an AutoCAD-like user interface – switching requires minimal training.
Perpetual licence possible: Many alternatives are available as perpetual licences – buy once, with no monthly subscription costs.
Lower total costs: Calculated over several years, the alternatives are usually significantly cheaper than an AutoCAD subscription.

System requirements for CAD software

CAD software – especially 3D CAD – places high demands on hardware:

Processor: Modern multi-core CPU – Intel Core i7/i9 or AMD Ryzen 7/9 recommended
Memory: At least 16 GB of RAM; 32 GB or more recommended for complex 3D assemblies
Graphics card: Certified workstation graphics card (NVIDIA RTX workstation series, AMD Radeon Pro) recommended for professional use
Storage: SSD for fast loading times and smooth working
Operating system: Windows 11 (64-bit)

Frequently asked questions about CAD software

What is the difference between 2D CAD and 3D CAD?

2D CAD creates flat technical drawings – floor plans, sections, elevations and plans. 3D CAD creates three-dimensional solid models that can be viewed from any perspective and used for simulations and visualisations. Modern CAD software usually offers both – 2D drawings can be derived directly from 3D models.

What is DWG and why is it so important?

DWG is AutoCAD's native file format and the most widely used standard worldwide for exchanging technical drawings. Most CAD software solutions support DWG import and export – for maximum compatibility when exchanging data with customers, partners and manufacturers.

Is BricsCAD really as good as AutoCAD?

BricsCAD offers full DWG compatibility, an AutoCAD-like user interface and all the important 2D and 3D CAD functions. For most professional use cases, BricsCAD is a fully fledged, cheaper alternative to AutoCAD. However, special AutoCAD industry functions and some add-on programs are not always available.

Which CAD software is best for architects?

For architects, AutoCAD Architecture or BricsCAD with architecture-specific extensions are the leading solutions for 2D plans. For BIM planning (building information modelling) we recommend Autodesk Revit or Nemetschek Archicad. SketchUp is particularly popular for conceptual 3D visualisations in early planning phases. For private self-builders, simple home planner programs are often sufficient.
