Opaque Glass Problem - Vector View

[JKEdmo]

Good morning,

 

This one has me stumped.  I have one patio slider whose glazing shows transparent even though I have the opaque window glass option enabled under Vector View.  All other glazed windows / doors appear opaque.

 

I had this happen in a previous project and now it's happened once again.  Bug?

 

Plan attached.  Any thoughts appreciated.

 

Thanks,

 

Jim

I ran into this just the other day!

It's happening because the window in technically inside on an interior wall because of the adjacent room that was created for the stairwell into the basement.

It all has to do with the Room Function that that particular stairwell room has assigned to it. Most rooms are defined as interior and only a few are defined as exterior. If you change the stairwell room to say a Porch the window will render correctly. You'll then need to manually delete the floor structure and finishes to get it back to the open below look.

 

Here is a screen shot from the Help section on Room Functions

Thanks!  Sounds like a bug to me, right?  I think I'll send it into tech support and see what they have to say.

Hello Jim,

 

Thank you for taking the time to report your concerns!

 

This issue is actually not a bug though it is a unique, but perhaps unfavorable, outcome of the current program logic as it relates to door glass and room type functions in this scenario. While our human eyes and minds tell us, “Hey! That’s an exterior wall on the outer side of the building!” the software can only tell exterior walls are truly exterior because they:

 

- Have an interior room on one side of the wall but no wall defined room on the other side

 

or

 

-There is an interior room on one side and an exterior or exterior hybrid defined room on the other side.

 

As Kyle pointed out in our in-program Help, our rooms types have specific non-editable functions that are either Interior, Exterior, or Hybrid, and an Open Below room is one of the Hybrid Room Types. What’s less clear from the current wording is that while Open Below is considered to be a Hybrid function room type, the unique opaque glass logic in doors specifically do not recognize Open Below rooms as exterior rooms while the other hybrid types are.

 

As shown in the attached section of our in-program help, interior door glass is intended to be transparent. There are not very many scenarios where open below rooms exist in an exterior context with door glass compared to interior scenarios. Most Open Below room scenarios are interior.

 

Again, as Kyle suggested, to get the desired result while still excluding a floor platform, it would be best to change the Open Below room to a different Exterior or Hybrid room type like Patio so that you can then navigate to the Structure panel and uncheck ‘Floor Under This Room’ to get the open below benefit while still using a room that’s recognized as an exterior room for the sake of the door glass.

Thanks Devin (and Kyle) for clarifying.

P.S. Props to Devin for detailed tech support response.  I think there are not too many software companies out there that offer this level of service.

Not a great solution, but you could also just change the material type for the glass in this window as opaque

Thanks Doug.  Good alternative.

 

Now that I think of it, not sure I fully understand why opaque glazing option should not be universal even for interior rooms.  I wonder what the logic is?

I think you make an excellent point Jim.  Perhaps you should make this case in the suggestions part of the forum.
