Okay,

moving the cutplane doesn't changes anything. I don't know how to make this clearer with a screenshot, but I made this one (attachement).

Strange, no matter what cut plane height I set, the 2 windows don't change visual, except when I put the cutplane ABOVE the windows, the view changes as expected. But setting the cutplane to go through the windows will give me this view.(Adjusting the cutplane also would not be the final solution, because we have to cut at a plane 1500mm above the floor, by government laws.)

I have read something about this has to do with sill heights etc? But just can't figure it out exactly, hoping someone could explain here...

Thnx!

Hello WW,

here is the window. You can adjust several things in it, let me explain:

-hout_dikte: thickness of the window profiles 

-raam: the type of window, VG=glass VR=fixed window L=left turning window R=right-turning window P=panel

- wand_dikte: thickness off the wall that's gonna be in front of the window (we draw our walls in 2 parts, inside &  outside)

-negge: the horizontal offset value from the window to the front wall.

Hope you understand. Thanks!

Your problem is your nested families. 

Why did you create the window this way?  This is really overly complicated.

Try deleting the nested families and creating what you need in this family.  Left - right can all be controlled with flippers.

The idea for the window was given by someone who does this for a living, so I thought, okay, he will know...

But also: if I should make every wiindow seperate, I would have thousands of seperate families. Okay, I could save out 1 version, indeed combine left & right, because they can be flipped. But I also have something like fixed glass, fixed window, a panel, a window that can only tilt. So that are 4 versions per window type.

Then we have double windows, for which can be chosen to make the left part left-turning, and the right part fixed glass, in example. This goes on to windows with 6 parts next to eachother. So that would mean for this window only, a really lot of different options, so a lot of different families. (not to talk about all these windows, with added upper-windows)

 Wouldn't I in that case ignore the idea of Revit, to work with parameters, to make flexible families...?

Thanks for the reply.

(no other way to fix this, even with the nested families?)

There are some very complicated families out that work very well but is it worth it?  In some cases it may be but in most, I don't believe it is.  Check out this thread at AUGI http://forums.augi.com/showthread.ph...it+content.com

The problem you are having is caused by some Revit viewing rules.  If a family is not cutable and if any part of the family is in the cut plane, the entire family is shown.  That includes invisible lines in the family.  Your windows show even if they are above the cut plane.  That means something in these nested families violate that rule.

Ok thanks, good hint, will check this out.

Thing is with our company, we design, make all drawings for the (how do you call that..) permit? And on top of it, make all drawings for our suppliers. (we build prefab houses). 

We've noticed that with previous autoCAD versions, some people don't take the time to make nice autoCAD blocks, so it looks okay, but really is not. Other people who are later in the building process can get a lot of extra work this way, to make everything okay. 

We discussed a lot on these subject with all kinds of personel, and agreed on making flexible but correct blocks for like windows. So, just to let you know there was some thinking behind it all....

Now for the part to make it work...

Thanks for the hint!
