Hello to all, this is my first post and I would like to start by saying how helpful this forum has been in my first couple of months on Revit 2008. Its great how people are willing to spend valuable time helping others (hopefully one day I maybe in a position to do the same).

I have a couple of questions relating to editing window families:

1. How do you deal with different sizes of the same window style within a project, I have been creating a new type (by duplicating) each within the family. Would it not be better to have the height and width as an instance parameter or does this affect the schedule which I have not been concerened with so far.
2. The host wall opening for doors and windows appears unconstrained, yet changes when the width & height changes? This appears to be the same in all the metric Famiies I have looked at.
3. For the attached window I have tried to delete the 'equal constraint' for the 'centre left/right' plane in floor plan 'Ref. Level' (currently measures 600 and 695). This is so I can add a dimension/parameter from one end so the frame is not equal. I can deselect the eq constraint and modify the existing dimension but why can't I delete it so I can add an instance parameter.

Many Thanks

Tim

1.  The reason they are type parameter is because on larger projects (non residential) we have window type "A" and it is always the same size, and if we want to change that size we just change that type, and not all of thoes windows.  Though it may seem annoying that every size is its own type, thats really best in most situations, and really it wont effect the schedual that I see, but really you should just have a type per size. 

The other two im unsure of at the moment.

6 months down the line I still can't figure out item 3 from my original post, I would be very grateful if someone can shed some light on this.

Thanks
