Function documentation

Is there any place where we have access to the available functions ? I am a Fortran 90 programmer testing out C# by fixing Eclipse-Reborn plugin. Since there were a few changes in where functions are stored or what functions are in calls since Twist was last on.

I'm particularly looking for the "Distance3D" function and since there is a call with
"Me.CurrentTarget.Distance3D" and it isn't referencing Distance3D from the current libraries

Also it seems like "Face" was removed from Vector3, is there a new equivalent function?

I think could be related to the change from distances being parameters to functions and requiring a new call type

Here are errors I am getting at the moment.

Code:
