Carapace - Free Perspective Tool

Carapace is a free and open-source tool for generating 1, 2 or 3 point perspective grids that you can use in any drawing program. You can even work backwards by starting with an image, drawing some trace lines on it, and generating a perspective grid that will match that image so you can draw on top of it with accuracy.

Only works in Windows. Must have .NET Framework installed to work, download that here: https://dotnet.microsoft.com/download/dotnet-framework/net472
