EQ breaks Parameter in Face Based Family

[esatis]

Hi, 

I am facing rather frustrating problem. In Face Based Family, when I put two RP in both sides of the Center RP and lock them with EQ (like I always do), then add Parameter dimension, I cannot input value in Parameter dimension without the EQ RP breaking the EQ lock. Is this a bug ?

Same setup in Generic Family, everything works as expected:

Sure, I added cleaned up family to my post.

Try placing a Labeled Dimension for half the width and then drive Half Width Parameter value in the Family Types Dialog Box with this Formula:  

[Half Width Parameter Name]=P_Width/2

It works!

Hi, 

thank you, yes I know this works, but it is clearly a workaround with one more parameter.

So if I am not missing anything, this clearly is a bug.

Just wanted to gather more info before reporting.

Happens to me too - but only in the Family editor. As soon as you load the Family in a project, it works fine.
