Align Dimension Line

2-D Dimensioning + Text > Edit > Dim.line > Align, 2 points 
These functions enable you to align the position of the dimension line according to an existing reference line for alignment, or according to two points to be identified.
- First choose an identification type for the dimension line.
- Identify the reference line for alignment, and then use the dimension figure to identify the dimension line.
You either identify a reference line, or specify 2 points, depending on the function you have selected.
The function has been conceived in such a way that the dimension line will not be placed on the same level as the reference line. You can set the difference in level in the Configuration Editor (ISDConfigEditor.exe) , via Drawing > Annotations > Dimensioning, 2-D > Distance of dimension line. You can, of course, also set it to 0.
