We’ve all been there: you’ve got a few days to throw together a prototype. For expedience sake, you go to one of your large, well known tools to get the job done. The files quickly become bloated and crash—hours of hard work lost. There’s got to be a way to create prototypes at a similar level of fidelity with a lighter weight tool.
