Relating a linear parameter to a linear constraint - Please Help

[harilalmn]

Hi All,

I am creating a dynamic block.

I have a Linear Parameter and a Linear Dimensional Constraint.

Is there any way I can relate them using a formula like;

 

Value of Linear Parameter = Half of Value of Linear Dimensional Constraint,

 

through an expression something like...

 

Distance1 = d1 / 2

 

where Distance1 is Linear Parameter and d1 is the dimensional constraint
