The project you attached is correct indeed, as is my example project with the partial redundancy removed. So this should fully constrain the arc, and as chrisb had pointed out, the issue is caused by partial constraint redundancy, and not lack of constraints. The whole arc is created as external geometry in the 2nd sketch, and the normal arc is created using the external center and 2 points. The arc in the master sketch is defined through center + 2 points (a center with 2 points define exactly an arc, actually 2 complementary arcs). You need here to refer to the center and one end of the 1st arc.

A wonderful support is provided at the official forum. A multilingual environment provides the better understanding of the software and a multi-platform support makes it fully functional and consistent on all the platforms. Moreover, FreeCAD can also be used as a library for other tools as well. It uses all the great free libraries for scientific computing to enable the user to add functionality as desired. Along with 3D modelling, this tool also allows creating 2D drawings.
