Ever heard of DesignSpark? They are releasing a powerful CAD package on September 16th — for free!

The company is owned by RS Components, a distributor of electronics and maintenance products. They offer a large library of 3D models of parts that they sell, dubbed the ModelSource. So if you are wondering how they are giving out software for free, that’s how. They also have free PCB designing software, and something called DesignShare which hosts open-source project collaboration, sharing and discussions.

By the looks of the demo video, DesignSpark Mechanical is a well laid out CAD package that is rich in features. The software allows for the import and export of several file types, and it looks like ECAD, OBJ, Sketchup, STEP, DXF and STL are all there, as well as the native file types. While it looks like you can import any files, we are willing to bet adding ModelSource files are by far the easiest and most convenient because of the integrated ModelSource library. But we think that’s a small price to pay for an alternative to SketchUp. After all, the component models will be useful for assemblies, even if you don’t order through them. Oh, and it’s perfect for making free models for 3D printing as it includes the ability to export STL files.

Watch the software demo after the break.
