3D CAD Software

3D CAD software allows engineers to develop complex models of real-world objects. Modify and optimize an object’s design, automatically detect interferences, and virtually analyze models—so you can iterate faster and focus on innovating.

What is 3D CAD software?

3D CAD software (three-dimensional computer-aided design) allows engineers to develop complex models of real-world objects so they can modify and optimize the design, automatically detect interferences, and virtually analyze models. In the application of manufacturing, 3D CAD software becomes a powerful tool that enables companies to automate and speed up the creation of downstream production deliverables. It also helps companies identify and resolve design errors early to reduce scrap and rework and, in the end, eliminate the reliance on costly prototypes for evaluation and analysis.

Benefits of 3D CAD software

Traditionally, 3D CAD software was used just to digitize and optimize 3D models. 3D models would have to be hand drawn, which could introduce many errors into the product development process.

Today, digitizing these drawings not only reduces errors—it also allows engineers and designers to advance their designs swiftly and collaboratively. In the new age of 3D CAD software, analyzing and reworking models to best meet design intent becomes smarter, swifter, and more agile—allowing your teams to speed up new product introduction.

3D CAD combines tools like CAE (computer-aided engineering) and CAM (computer-aided manufacturing) to create a powerhouse of modeling options, along with model-based definition (MBD) to maintain a single source of truth for all model data. Add in the capabilities of generative design, real-time simulation, additive manufacturing, and augmented reality, and your design teams will have all they need to keep and increase your competitive advantage.

Business benefits of Creo’s 3D CAD capabilities

null

Using PTC Creo, engineers can rapidly create and automatically update 3D geometry and the associated downstream deliverables across the value chain—all to help users reduce time-to-market by increasing engineering productivity and efficiency.

Consider the impact this could have on your new product introduction time. Using 3D parametric and direct modeling capabilities, users can quickly create, evaluate, and improve design options—so engineers can quickly arrive at the optimal solution. Virtual analysis ensures design flaws are identified and resolved early in the product development process, eliminating the high costs to create and test physical prototypes.

Detect and eliminate design flaws while enabling engineers to focus on quality and innovation. Using integrated analysis and 3D design tools, you’ll be able to streamline and automate changes without requiring additional resources.
