How to Prevent a Linear Dimension from Automatically Selecting Both the First and Second Objects?
Solution
Note that this only occurs when assigning dimensions to linear "Drafting Line (Extracted Edge)" objects in a drawing and not to any other type.
Instead of using a linear dimension, users can hold down the Shift Key on the keyboard and select the undesired object. Next, in the dialog select the unassigned object and then select the correct object on the drawing.
This method is described in the NX documentation on the page "Deselect objects".
A simpler and quicker method would be to change to using a Perpendicular Dimension which will never auto-assign itself and requires users to manually select both the first and second objects.
