Combine shells 2 + 3 at the wizard level (and if reasonable/feasible, floors
below as a 2 or 3 story shell), defining the roof construction that will be
exposed in the wizards (as a custom construction if possible). In
detailed mode 2D or 3D view, scroll through the Shell 2+3 spaces, and simply
right-click </span><span style='font-family:Wingdings;color:#1F497D'>à</span><span

there are reasons NOT to make 2/3 story shells in the wizards based on my

as necessary wherever the lower floors are exposed. (So create your shell 2/3
as one shell and create a roof(s) above the zones in shell 3.) This requires
copying/modifying polygons, which I find easier to do within the input files.
After you do it a couple times it’s not so bad.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-GB style='color:#1F497D'>A while ago I posted
a question about the use of shells and receive some very useful responses
explaining that best practice is to use different shells for each
exposure/adjacency combination. I have a follow up question to this which is a
little tricky to explain but hopefully the attached will help.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-GB style='color:#1F497D'>The attached shows
two shell variants for the same building. The top floor (shell 1) is smaller
than the other floors. Therefore, for both variants the floor below is broken
into two shells; shell 2 which is exposed to the top floor and shell 3 that has
a roof exposed to atmosphere. My question relates to the floor below these. Can
this be comprised of a single shell which spans both shell 2 and 3 as per
option 1, or does it need to be broken into two to match the shells above as
per option 2?<o:p></o:p></span></p>
