If you have read about explicit, geometry-based 3D CAD, you know it is the best approach for creating flexible, lightweight designs. Now, PTC brings you a free download from the CoCreate product family - CoCreate Modeling Personal Edition, a 3D CAD system you can use for assemblies with up to 60 parts.
Download a FREE version of CoCreate Modeling Personal Edition today and see how liberating an explicit, geometry-based 3D CAD system can be.

CoCreate Modeling Personal Edition Features:
1. Achieve faster design cycles by leveraging the strengths of an explicit approach to 3D CAD CAM product development
2. Learn the easiest approach to 3D modeling with design creation and modification that follows familiar Microsoft Windows “copy-and-paste” and “drag-and-drop” actions
3. Drive 3D product design through on-the-fly interactions with geometry and feature recognition
4. Confront unpredictable or radical design change with flexibility
5. Work with multi-source CAD data as easily as if you created it yourself
6. Eliminate resource bottlenecks by giving everyone the flexibility to quickly pick up existing designs and carry them forward
