Involute of a Circle in Solvespace

In this Solvespace new tutorial I'll demonstrate how to create a involute of a circle. This video is the first in a series where I will create an involute gear and demonstrate how one involute gear drives another. Before we can do that we first need to create a involute of a circle to get a better idea what it is. This video will be followed by another one that explains which parameters are involved to create a involute gear and a third where we actually design the gear in Solvespace. I've used version 2.3 in this video but v3.0 should work fine too for this tutorial. Solvespace is an open source, parametric, 3D CAD program that is lightweight and easy to use. It is available for GNU/Linux, OSX and Windows. In Solvespace the user applies geometrical constraints to a sketch and the program's solver calculates the result (comparable to the FreeCAD part design workbench). Solvespace is open source (GPLv3 license) and is available for Window, OSX and Linux. Originally developed by Jonath
