Parametric Dimension

While I have used parametric dimensions in Inventor, I am  trying then in Autocad  (2025) for the first time.  The problem I have is I can't seem to do perpendicular dimension to 2 parallel sloping lines.  I managed to get it to work by changing the UCS to align to the slope but when I change a dimension, the dimension no longer aligns to the slope.

 

For example if  I change d5, then d11 and d7 do not measure the true perpendicular distance.

It's a bit clumsy but since you need two vertices that are prependicularly aligned between the two parallel lines you can add a couple of construction lines to be referenced by the align dimensional constaint and then freeze the construction line layer.

 

For example, in th eimage below the red lines have a perpendicular constraint while the magenta lines have a collinear constraint.

The d7 and d11 constraints are to the endpoints f the red lines.

These constraints remain appropriately aligned when HLong is changed.

Freezing the layer hides the construction lines.

Thanks for the help.  I had tried construction lines but did not have enough/right constraints to get this to work.
