Dimension position for objects on the same axis / coordinate

[bigcarl5000kg]

Hi everybody,

I have some plate example with holes (symbols and object X-/Y-axis here), 

where some holes can be (are) on the same X- / Y-coordinate (one axis), or they can be (are) on the same X- / Y-coordinate of some contour point. I use one dimension chain only.

I have divided the plate vertically and horizontally into halves in the dimension style and then create the dimensions in the appropriate direction (holes, contours, extremes). Probably for the above reasons, not all holes have their own X- and Y-coordinates.

1) How can I determine which side (top / bottom) is the X-dimension of the holes that are currently in the vertical object center / MP center (see sketch with object axes)? Here it makes double.

2) What do I have to do that the Y-dimension of the holes per side (left / right) does not stop at the first object if there are several holes on the same horizontal axis. Here some objects (far from the sheet metal edge) do not have any Y dimensions at all.

3) For the hole that is close to the center of the plate, I don't get any X-dimensions, the problem is similar to point 2, but identical X-coordinate here with an object edge (455) below. How can I solve this?

I need, the corresponding contours in the given direction (left, up, right, down) and the holes of the given half of the object to be completely dimensioned in the right direction. 

Many thanks in advance

Example data here:

For one side holes dimension (all upper direction) I get this result:

For another one side holes dimension (all bottom direction) I get this result:

Hmm, still not all Y-coordinates are here - where is the problem?

OK, after longer communication with my supplier (Paul thanks!), it is currently not possible to solve this other than by manual intervention in the dimensioned details (super-natural-ideal method with the expected result in the future updates / revisions). For objects that occur in the "grey transition zone" (vertical and horizontal center SP / MP) it is not possible to unambiguously determine the position of the dimension, if the dimension chains were placed on all sides of the object (top / bottom).
