Hello,

I'm very new to Revit and I've just run into yet another item that I've spent an hour researching and can't seem to find an answer for. I downloaded a simple brick window from the downloads section and I'm experiencing a weird phenomenon when cutting through the window when the height gets too small. I could see how if the width go too small it wouldn't display properly or even let me assign something under 6" as the jambs would overlap but this height business doesn't make a bit of sense! 

Here is the file location so you can test it yourself:

https://www.revitcity.com/downloads.php?action=view&object_id=5415

For example, I'm working on a home and lets say I have two different size windows. Using this family I create a few different types, one that are 20" wide and 26" tall, another that is 20" wide and 25" tall, and another winodw that is 20" wide and 20" tall.

I've uploaded a sample file with the different windows already sized and loaded. Nothing is different between these windows other than the height. Once the window gets under 26" in height they start to appear different when being cut. All of the windows are placed at the correct height to go through the window at 48".

Any help would be greatly appreciated, thanks in advance!!

Believe it or not, windows will appear different depending on where the window is cut in the family.  Experiment with this and see if it is your problem.

Unfortunately I didn't create this family and have almost no experience in working with families. With that said I did change the cut plane to every single 1" increment and the windows appear to cut differently once they are under 26" in height...just plain weird. I don't know if there's a way to assign a cut plane in the familiy or something to better control how they look.

More help is needed. Maybe someone with a good knowledge of families can help out.

Thanks!

That’s what you get when using 3D geometry in plan view. In the window family, make 3D geometry invisible in ‘Plan/RPC’ and ‘When cut in plan/RCP…’ and draw 2D lines (use pick line tool, lock).

Thank you pijpiwo! This has helped some of my problems. As I mentioned I'm not by any means even a rookie yet with families. When I use the pick line tool, I'm in the plan view, and I select all the window pieces I want to see. Unfortunately when I reload the family I don't see any of those lines. Is there anyway you'd be kind enough to explain this a little more on where I should be drawing these lines or update the model that I uploaded?

Thanks!

In the window family, select 3D elements (frame, glass, etc.) and in the visibility settings uncheck those two options (pic 1). Elements should turn halftone.

Draw symbolic lines (2D) by pick lines option and choosing correct subcategory (pic 2).

Thank you so much! I really appreciate you helping me out with this issue and updating my Revit file.

I completely missed the subcategory and probably didn't put it on the correct one, therefore it wouldn't show up.

EDIT:

I see you used Symbolic Lines to show up in the cut plane and not Model Lines. I'd never heard of these before and used the wrong lines in the last post. Thanks pijpiwo!

Yep, when you apply a wireframe view option in the project, your model lines should show, but symbolic lines is the way to go in this case.

Cheers!
