One thing has confused me for a long time.

 When we set up a yes/no question, by default it comes as grey checked. We can uncheck it or check it again. But it's no longer grey. Any difference here?

Are you talking about the parameter from family editor? if so, most likely you won't see the effect until you load the amily into the project.

What are you using it for in the project?

when the checkbox is grey, i guess you have selected more than one elements, then it will be in grey, (in other words, there are some things that are checked "yes" and some are "no" but once you check the box again, you are overwriting all the element.

hope that explains your situation

usually when this happens it means you have multiple elements assigned to that yes/no paramter and some are checked and some or not checked.  so it does not know what to give you except a grey check box.  if you change the grey check box to blak check you have turned on all the elements that where off (sharing that parameter) if you uncheck the box completly you will turn off all the elements.

I reiterate this, I am not selecting anything, just in a view, and I add a yes/no parameter to all the views. It comes as grey.

Then I guess it is in a state of limbo, The box does not know weather it is (yes or no) til you tell it.

 I didn't read all the threads, my mistake.

I gave it a try and mine is grey too.  This is the only conclusion I can come up with is the "limbo" state.  When you assign a Yes/No paramter to something say a wall, do all walls take the yes or the no? or is it waiting for you to tell it one way or the other?

The grey is an obviouse way of saying "hey, you havn't addressed me yet, Am I yes or no?"  and yes is the default.

ok i agree with cadman, when you first set  up this project parameter, by default, they are grey since nothing has been assigned yet, so you have to phyically un-check the checkbox, check it again to determine what you want for that "view" so the grey color means it is a undetermined state to my understanding.
