Hello every one ….
I make a dynamic block and when i make a distance constraint Parameter AutoCAD give me this message in command bar
can some one explain this please ??
i uploaded the dwg
AND Thanks in advance ....
WHY THIS MESSEGE (Cannot add distance constraint)
I don't have full AutoCAD so cannot fully help you.
HOWEVER, is your version of AutoCAD up to date with the latest patches?
Also try exploding those two blocks and then adding your constraint. It might be a case of AutoCAD not being able to add constraints to blocks.

The elements of your block definition reside at different Z-levels.
Parametric works only with 2D geometric objects and all in the same plane.

That means they will only work if the Z is the same level for the geometry. So if one Z=0 and one Z=45 it won't work

In >>this video<< I demonstrate with a simple example, that parametric constraints/dimensions will fail if any 3D geometry is involved. (And of course also not in a block definition).
This is one of the regrettable limitations of AutoCAD's parametric tool.

One possibility:
Open (Go into) the block definitions (bedit or refedit command) and move the "wrong" placed geometry to Z=0 as shown in >>this example<<.

Some simple tests as >>this<< should answer your question: Parametric dimensions and constrains work (with very few exceptions) only in the XY-Plane.
