missing zones

When drawing zones in the DD Wizard with a CAD background imported, I finish defining the zones and go back to screen 2 of the wizard. At this point the final 4-6 zones I defined do not show up in the white and grey image of the footprint and zones. Is there a maximum number of zones that can be defined in a shell? (I was up to ~80 zones on this floor of 120,000 ft? and have reduced it to 65; either way, any zones I add do not show up on screen 2.) Two screen shots are included below.

If I delete the "last" zone on the Zone Definition screen, save the zone changes, and go to screen 2, a zone 4-6 zones prior is no longer shown on the white and grey image. I could continue to describe the intricacies of the problem, but if you've experienced this, you probably don't need further explanation.

Is there a fix for this? It is especially bizarre because I defined several floors after the one that's giving me trouble and had no issues. Any help is greatly appreciated.

There is a limit to how many zones you could add to each shell. You might want to add more shells if you really need to model all the zones. Just be careful you remove exterior walls when you are in the detailed mode.

Thanks Arturo. Do you know what that limit of zones per shell is? I looked through the eQuest documentation I have and couldn't find anything.

I have my suspicions about this theory because I deleted zones until I was down to ~65 zones and was successfully removing zones 1:1 on the Custom Zone Definition and screen 2 of the wizard. After getting to this point, any zones I added (even just 2 or 3) on the Custom Zone Definition screen did not show up on screen 2 of the wizard.

Maybe the best option, as you said, is to split the level into two shells and go from there....
