What is 3D CAD software?

3D CAD, or three-dimensional computer-aided design, is a technology for design and technical documentation, which replaces manual drafting with an automated process. With a computer, architects, engineers, and other professionals can use 3D CAD software to more precisely represent and visualize objects in a virtual setting, using a collection of points in a three-dimensional space.
 

Autodesk has a broad portfolio of 3D CAD software, with programs and tools for drawing and 3D modeling to help people explore and share ideas, visualize concepts, and simulate how designs will perform before they are made.

In manufacturing, 3D CAD software helps streamline the prototyping process.

Examples of 3D CAD workflows

3D CAD software enhances professional workflows across industries by offering advanced design, simulation, and visualization tools. Beyond traditional fields, 3D CAD software finds innovative applications in health care, entertainment, education, and fashion, demonstrating its versatility and impact.

3D CAD for manufacturing

In manufacturing, it allows for creating and analyzing complex product models for early identification of design issues and helping to streamline the prototyping process. Early detection conserves resources by reducing the need for physical prototypes. It also accelerates product development cycles, seamlessly integrating with computer-aided manufacturing (CAM) systems to smooth the transition from design to production.

 

3D CAD for architecture and engineering

In architecture and engineering, CAD software enables more precise modeling of intricate structures, incorporates environmental and structural analysis, and harnesses building information modeling (BIM) technology for enriched data management. This comprehensive approach improves project coordination, reduces errors, and cuts construction time and costs.

3D CAD Beyond Traditional Workflows

Beyond traditional fields, 3D CAD software finds innovative applications in health care, entertainment, education, and fashion, demonstrating its versatility and impact.

Types of 3D CAD software

CAD software systems are diverse, catering to design and engineering requirements with varying levels of control and functionality. Freeform modelers such as ZBrush and Autodesk Mudbox represent one end of the spectrum, offering minimal dimensional control for users to sculpt designs, akin to virtual clay. In contrast, parametric modelers such as CATIA, Creo, and OnShape provide exhaustive control, so every design aspect can be meticulously defined by dimensions and constraints. This approach builds a comprehensive history of the model’s development, enabling deep customization through scripting.

 

Between these extremes lie other modeling techniques including polygonal (mesh) modeling, utilized by Blender and Autodesk 3ds Max; solid modeling, found in SolidWorks and SolidEdge; and surface modeling, as seen in software such as Autodesk Alias and Rhinoceros. Each method offers distinct advantages, from simple shape manipulation to creating complex, ready-for-manufacture models.

 

In the realm of 3D CAD software, Autodesk embraces a hybrid approach across a suite of design products, blending the strengths of various modeling techniques to serve a broad spectrum of industry needs. Autodesk’s software—including Autodesk AutoCAD, Autodesk Fusion, and Autodesk Inventor—integrates features of solid and surface modeling with parametric capabilities for a highly flexible design process that accommodates everything from initial concept sketches to final manufacturing-ready models. Fusion combines mesh and solid modeling, seamlessly transitioning between design phases. AutoCAD’s extensive toolset accommodates a wide range of design tasks, making it a versatile choice for professionals across disciplines.  Inventor provides specialized toolsets that automate the 3D modeling of sheet metal, weld frame, piping, and electrical components.  It also features powerful rules-based technology, so designers can quickly create new configurations of existing designs for the next project or to satisfy customer requests.
