Automatic zone detection not detecting boundaries manual zone boundary gives wrong door number

Niranjan Das Sharma — Tue, 09 Sep 2025 06:47:22 GMT

I was trying to define zone and extract door window numbers and other data.

I was getting wrong numbers when i use manual polygon zone method.

automatic is not detecting boundaries.

this is the screen shot of original space to mark zone. which was failing to detect

This is a simplified version of same space reatining only the wall and removing all doors, windows beams and everyting else. Its still not detecting. where could be the possible leak? Pleas help

The zone needs to have the same renovation status as the walls.

All are new walls.

But is the zone you are placing also 'New'?

If not it will not be able to find the wall boundary.

are the walls you've placed set to Zone Boundary for its Relation to Zones setting?

Yes all four walls

With the same wall properties and zone properties if i make a new enclosure, it works!

If those 4 original walls are all zone boundaries, are all "New' reno filter, all the reference lines connect with no gaps, and the zone is 'New' reno filter as well, then is should work there as well.

If not, then one of those settings must be wrong.

If it works for a new enclosure, there is obviously no problem with the software or what you are doing.

It worked when i copied and pasted the same geometry in a new file!

... And also worked in the old file when I made the geometrie's design option to 'main model' !!

Ahh yes, it seems it also needs to belong to the same design option.
