[Equest-users] Internal Wall Problems with Wizard

[Nathan Miller]

To further clarify, if you look at the walls you highlighted as “missing” in 
Image 1 (when you select the smaller space), you will see that they appear 
in Image 2, meaning as Robby indicated, they are a child component of the 
larger space that surrounds the smaller space. You should be able to select 
them and verify that the NEXT-TO field is properly entered.



Also, I thought that the space that gets “possession” of an interior wall 
has something to do with the order that you draw them in the wizard, but it 
has been a long time since I cared to check on that.

Regarding the comment about not trusting eQUEST's snaps, I find it helps to 
turn all snaps except "Polygon" off when defining zones.  Thus the only way 
it's snapping is directly onto an existing vertex.  I use this every time 
and don't have any issues with interior walls.



Omer-

I believe what you're experiencing is that when defined properly, eQUEST 
only defines ONE interior wall.  Since an interior wall is used to define a 
relationship between two spaces, there is only need for one wall.  The zone 
that own's the wall is rather arbitrary, because either way they are linked 
through the NEXT-TO command.  If two walls are created by eQUEST, it's 
likely that they'll both be ADIABATIC and this is a symptom of not defining 
the wall geometry correctly.  One wall per zone interface is what you should 
be shooting for.

Hi Robby,

Thanks a lot. Learned something very important today.

Another problem that I am having with internal walls: There are internal 
walls missing in some zones and I have no clue as to why. You will see these 
in the attached images as thin lines. The walls are missing from the 
selected zone (grayed), but the neighboring zone has walls in the same 
place.

In 01.jpg, all three internal walls of the smaller zone are missing.

In 02.jpg, some internal walls are missing and some are not.

This floor has been recreated according to your advice with additional 
vertices.

I think there is more to internal walls in Wizard that I do not know.

Omer,



The simplest way to ensure that eQUEST defines the NEXT-TO property 
correctly is to make sure that each interior wall only interfaces with one 
other interior wall.



In the situation you describe where you have an interior wall that is 
adjacent to more than one zone, I would typically split that interior wall 
into two or three walls by adding vertices at each of the intersections 
between the zones and the interior wall that spans them.



Here's a sketch of what I'm describing:

Hope that helps.

Dear All,

I have realized that while creating the model after Wizard entries, eQuest 
will fail to determine the NEXT-TO property for interior walls that are 
adjacent to more than one zone and all those interior walls will be defined 
as ADIABATIC.

Also, I see that interior walls are missing from zones where another zone 
has an ADIABATIC wall in the same place.

I see no way of having a model with all interior walls correctly defined 
without fixing all these problems after the Wizard. Does everybody have the 
same experience or am I missing something?
