Constraints have no effect on dynamic block properties

[mehdi-guida]

Hi

why constraints have no effect on properties handles ?

how can i solve that?

Thank you

You're asking how to make constraints affect dynamic parameter grips?  You can't.  

Why don't you use geometric constraints and use their grips?

Tell us more detailed what you want to do (to achieve).

I don’t know any thing about geometric constraints? 
could you send me an example or video ?

Thank you

I think i misunderstood your mean in your last message. I used geometric constraint for make parallel two lines but if the lines have another action ( for example stretch or scale action) , constraint only affect on lines not on their actions.

Don't never mix geometric constraints/dimensions with dynamic parameters/actions in a block definiton. To get changeable geometry in a dynamic block use either only the one method (geometric constraints and dimensions) or use only the other method (dynamic parameters and actions). Otherwise you will get unexpected results.

I used the wrong word.  I meant to say 'dimensional constraints'.
