You can build FreeCAD from his branch. Instructions are available on the FreeCAD wiki, depending on the OS.
Hate to sound like an uninformed moron, but can you direct me to the appropriate page on the wiki? I want to make sure that what I found is correct. (https://wiki.freecad.org/How_to_install ... orkbenches) This is very new to me; I honestly do not know what or how to do this.

@LVAeronautics Those are the wiki pages with instructions for building FreeCAD from source (GitHub branch):

Compile on Windows
Compile on Linux
Compile on MacOS

Thank you, but we won't lie on this end; not knowing software coding the way alot of you all do here, that page has us lost in the sauce big time. I wish we could say differently, but we are aero & flight test guys. We do know a few chaps who might be able to walk us through a compiling. We'll try to figure it out, but in the meanwhile, we will make do manually!

@kemes Any chance for PR in master or is this project abandoned ?
The project is not abandoned. I just have not had time to carry on. The project has not seen many steps yet, basically it has the icons done. Nothing more. Therefore I have not seen a reason for a PR.

Make use of ordinate dimensios is convenient when we need to specify location and tolerances of certain features of an object respect to a central point, in example the guide pins and cavities of an injection mould need to be aligned respect to a central axis like this:

In the future I want to develop an injection mould using Freecad, I began with something simpler but with the same principle, ordinate dimensioning is a cleaner and pertinent method, nevertheless the current Freecad tools have the following inconvenients:
  1. Balloon arrow is fixed to only a point over an object, cannot be fixed to any point over the object or line span. In example is not possible to add an arrow at the endpoint of a centerline of faces, circles or arcs.
  2. Balloon Text have not the split line possibility.
  3. Customize format label is not set by default in the Task Window of any text insertion tool in example special characters should be added after balloon annotation insertion; is tricky to add it in annotation or text rich annotation tools, you have to copy paste.
With some effort I get the following result, hope this experience could be useful for the tool development.
