How to get the "Master Layout Settings - Grid Setup" data?

[ReignBough]

I've tried using the APIEnv_GetNumberingGridLinesID. It gives the grids coordinates and based on these lines I can get the following:

• Number of Cells
• Distance from Margin
• Grid line type (and color)

How/where can I get the "Start from" and "Primary Direction"? (When I got the grid lines, I assumed that the start and end points of each lines will tell me the "Start from", but they don't.)

- OR BETTER -

How/where can I get the complete information about this settings?

EDIT 1:

I found out that the grid values are the one shown on the layout. That is, if a grid was split into two by a drawing, this will now become two grid values.
