What sort of constraints that may achieve this behavior?

 

In the screenshot below, I need to have symmetric behavior. For example, in case I stretch the indicated part of the drawing then I need the other corresponding part is to be stretched accordingly.

 

What constraints settings might achieve this?

 

The drawing is attached

 

Thank you for the help,

 

Best

 

Jamal

use the equal (=) constraint

 

you need to use the constraint dimenstions.... not regular dimensions

 

see attached...

thank you for the help zzz144.

 

the issue now is: if i change the dimension to be 2.5, then regular diemension doesn't change accordingly!

ah yes... you will have to redimension... because the true dimnesions lost their associativity... 

 

just be careful how you dimension...

then in this simple case, much more manual work is still needed!

 

why ther is no way to let the regular dimesnion responds automatically?

 

there should be a way. otherwise, the parametric is not useful.

 

what do you think?

well you are sort of correct. autocad is not meant to be parametric. this constraint and parametric dimesnions are simply a little experiment/addon they built in just recently... and it has its bugs... 

 

manual dimensions will obey the drawn geometry for as long as they can.... 

 

whereas the parametric dimensions when they cannot obey the geometry they simply cease to exist.
