"As announced at Oshkosh AirVenture 2016, EAA members can now download SolidWorks Student Design Kit—EAA Maker Edition for free.
The EAA Maker Edition of SolidWorks provides the ability to create fully detailed parts, assemblies, and drawings; the ability to generate complex surfaces, sheet metal flat patterns, and structural welded assemblies; and will include wizards to automate designs, check for interference, and perform simple stress and flow analysis."
I know there are some pilots / aircraft mechanics on this board. This is a huge perk! To anyone else, EAA membership is $40 a year. Might be worth it for people who want access to a massively powerful modeling tool.
