Zone Issue

Anonymous — Wed, 24 May 2023 11:00:30 GMT

Hi guys, I'm trying to create zones after I create walls, but I keep geting this error:

No closed polygon found around the clicked point, but one has been found outside the clicked point. Accept it as a Zone?

Note: Elements may not be connected properly, or may not form a closed polygon due to their renovation status.

The division is closed, and I have different renovation status but they are as it should be. Also all the walls have zone boundary selected.

Can anyone please shed any light in this issue?

Thanks

I am also experiencing this problem. I have resorted to re-modeling entire sections of a large school that I am working on, but the problem persists (not everywhere obviously, but in particular spots).

I will trace around certain rooms if necessary, but as we are only just evaluating Archicad as an office and I am one of it's main proponents I would hate to think we have to employ a bunch of workarounds already...

The walls are probably not aligned...zoom in and you'll find a tiny gap...use the Adjust button to "seal" the gap if you find it hard to snap. You can adjust several walls in one operation. /Mats

In your wall settings, check under Listing and Labeling the 'relation to zones'. Default option is Zone Boundary.

Always assume it is a user error, not a bug. Take the following steps:

1- Magic wand a fill into the compartment. If it works, the problem is in the zone, go to 5.
2- If it does not work, the problem is in the compartment, use a line and cut the compartment in half, then magic wand a fill into each half.
3- Cut into half the area of the room where the magic wand does not work.
4- Repeat steps 2 and 3 until you have zoomed in on the problem.
5- Go through steps 2 to 4, using a zone instead of a fill, and a wall instead of a line.

I believe the walls are all aligned because all the wall skins are merging fine, also all the walls are set to zone boundary.
Miguel's solution allowed find that the issue was on the two inner walls, but I've tried to change them, move them and even making the go beyond the limiting wall, but the error sill happens. Any more ideas please?

Are you using complex profiles? These can create issues with other elements.

Indeed they are complex profiles!
I am using the tutorial on your blog (cortes 1:50), and the wall that has issues is exactly the ones with complex profiles! Is there any way to solve it?

Try to change the height of the bottom of the zone or the wall, or both. I have had some problems when the bottom of the zone is beneath the bottom of the wall.
Glad to hear that someone is finding the blog useful

We have run into this problem as well, everything appears to be drawn correctly, no gaps, right heights, etc but still persists.

This appears to be based on the Renovation Status of the zone itself. If the zone has an existing status it will ignore walls with a new status. Once the zone is changed to new, it recognizes the boundaries created by new walls (or other boundary objects). Don't know if that is documented anywhere, we stumbled across the solution.

Bingo! this was the answer to the problems I was having with automatic zoning. I changed the proposed zone to NEW in the renovations pallet before clicking inside the space and now it works.

Thanks Kevin!

GS please change the reference guide to make this clear for users.

I checked into this and yes, Zones with a certain Reno Status will recognize only zone boundary elements (Walls, Columns, Lines etc.) with certain Reno Statuses.
So:

A Zone with "Existing" Reno status will recognize elements with "Existing" Reno status.
A Zone with "Demo" Reno status will recognize elements with "Existing" or "Demo" Reno status.
A Zone with "New" Reno status will recognize elements with "Existing" or "New" Reno status.

Or, if I want to look at it the opposite way:

A Zone with "Existing" Reno status will NOT recognize elements with "Demo" or "New" Reno status.
A Zone with "Demo" Reno status will NOT recognize elements with "New" Reno status.
A Zone with "New" Reno status will NOT recognize elements with "Demo" Reno status.

I have also informed GS about this so they can include this info in the Help files.

For me, the issue is that my zones do not ignore walls set to "no effect on zones" or any other setting that allows the zone to "flood through". All walls seem to be accepted as Zone boundaries.

If I copy all the walls and the zone to the side, outside of the building, it works as it should. I have no idea as to what could be causing the issue. Any thoughts?

I am about to make a copy of the whole thing and start deleting elements to see what could be the issue.

Thanks laszlonagy, what you say makes sense. I think what throws people is that the error message that comes up is "software speak" and doesn't say anything about renovation settings. Presumably the software has detected that the renovation setting is the problem, so the warning box should say so.

AC is so complicated now, whenever you run into a problem you need to have a checklist on the wall next to your computer

Is it A...?
Is it B...?
Is it C...?
Is it D...?
etc

I agree with you, Warning Dialogs could have one sentence clues included stating what should be checked to solve the issue. Would be very helpful.

I figured it out in my case.

I had to recreate the wall.

It turns out that all walls that had been cut were not working with the zone tool.

Hello to all!
New to ArchiCAD and I am facing a zone issue in one of my projects. I have a room but when I try to make a zone it says that "no closed polygon found". I tried with the fill tool to find where the problem is and as you see in the attached image, it is in the connection between the wall and the column. For sure these are adjusted and are on existing status. Where could be the problem? Thanks!

Does the Wall butt against the side of the Column?
If so, that could be the problem.
Make sure that the Reference Lines of the Walls connect properly and then there should be no error in the Zone recognizing its boundaries.

Exactly! That was the problem. I thought that when you have a grid of columns, when you connect them with walls you cave a closed polygon.
Apparently the walls have to intersect inside the column so as I can have a zone. Why isn't this done automatically as as the walls touch the column?
Hope this intersects only the reference lines and not raises the wall's area

Re: Zone Issue

Laszlo Nagy — Mon, 04 Mar 2019 17:04:55 GMT

The body of the Column is automatically cut out of the body of the Wall and that will be reflected in the area and volume of the Wall, so no worry.
