Hello,I'm trying to make a block for a plan view of a generic window.  What I'm looking to do is have it set so mullions are added by array but the locations of these mullions can be adjusted (slid).  I had one made which would ask how many mullions you needed and just unhide each until the correct amount, but for large curtainwall type applications this could be upwards of 20+ mullions.  Any clue if this is possible?Hope this is clear enough,Thanks,Rob

Possibly use a dynamic block?

You can build a dynamic block and use the array parameter, but you'll have to set the spacing (distance increment).  And this means of course you won't be able to "slide" and adjust for different window dimensions.  They'd have to be fixed to multiples of your spacing.You could build several dynamic blocks however using typical spacings.Unfortunately the array parameter in dynamic blocks doesn't work the same way as the array function in the drawing.  Maybe Autodesk will make it that way eventually if enough people ask for it.  But that isn't yet.Dave.
