The 2.0.0 series (the master branch on github.com) of LibreCAD uses a new snap system which is designed to be more efficient in use.
For example, snap by middle points is extended to multiple equidistant points on entities. Using this new feature, trisecting an angle is now possible, albeit in LibreCAD.
To demonstrate this new interesting feature, 6 trisecting lines of a triangle are drawn, and Morley’s trisector theorem says the deep blue triangle formed is an equilateral triangle.
