=== Free 3D Modeling Software for Pumping Station: One Members === | |||
We have access to SOLIDWORKS Educational licenses for free through the space, details are at [[SOLIDWORKS for Pumping Station: One]] | |||
We also have free access to Dassault Systemes 3DEXPERIENCE, which is a full engineering suite that runs in the browser. This includes browser-based parametric CAD, subdivision surface modeling, and programmatic design apps. For onboarding, email [mailto:cnc@pumpingstationone.org the Industrial CNC Area Host]. | |||

AutoDesk Fusion 360 is not open source but is essentially free to makers and education users. To get the free copy: download trial, when trial is up and it asks for license number there is a checkbox to say you will not make money on the products you make. (citation: personal experience) You can buy a single-user license for Fusion 360 pretty cheap too, or wait for sales that have been up to 90% off. Generally though, the free download covers almost everything. Expect to see paid extensions and features in the future, I bet. There are meetups at PS1 to support Fusion 360. http://www.autodesk.com/products/fusion-360/overview | |||
