Zone Gross Area Does Not Show in Stamp,Why?

[Anonymous]

Hi,
I have started to use Zones, but I am having problem for the Stamp to show the Gross area even-though I have chosen the last icon, the GROSS radio button, it always shows the Net area?!
Also the colors zone area does not extend to the reference line of the surrounding walls for the GROSS option as it shows on page 296 of manual (on line help gives a better picture). I am using the "Zone Identifier 2", any help would be appreciated.
Thanks,
Joseph Harouni

Hi Joseph,

... having problem for the Stamp to show the Gross area even-though I have chosen the last icon, the GROSS radio button, it always shows the Net area?!

I believe that this is the way it's considered work (?) The only difference between net and gross area is that the net area recognizes the inner boundaries of the room's surrounding walls - Zone is placed inside this boundary. and gives you the measured area.
The same measured area commes up when selecting the gross alternative, but the zone boundaries finds the walls' reference lines instead (measured area will be the same in the 2 alternatives).

You can always check the additional zone calculation settings under Options/Preferences/Zones if you'd like to finetune it.

Also the colors zone area does not extend to the reference line of the surrounding walls for the GROSS option ...

Use the "Bring to front" option under Tools/Display Order to move the 2D Zone fill "above" the walls' fills (when zones are active in plan that is)

Thanks for the help,
I did tried to fine tune in Preferences/Zones but still I get the net area vs. desired GROSS (I checked off wall & column subtraction). Am I missing a point or it is not doable? If not what is the purpose of GROSS area (our code in Los Angeles, CA requires that measurement).
Thanks,

It might be a mistake from GS's side cause one would think that gross area should add number of meters as it extends the boundaries for the zone.

You can always use the "free hand" construction method (# 1 in my pict);
-if it is an enclosed area just do your settings for the zone tool and be sure to select alt. 1 button in constr. meth. Then just "space bar"+ click in the enclosed area and AC will find the closest boundaries.

-or click your way around the needed area just like you'd do with poly forms for fills and slabs ....

I think Joseph has found or is first to get to a problem with the GROSS Area tool. I see a correct calculated value in the dialog box, but can't do anything to get it to display the proper value.

Using the gross area zone category, turning the room name off then selecting use category as name and turning the zone name back on, I was able to get GROSS AREA to show up on the label, but not the dispayed value for Gross area as its is displayed in the Zone Settings dialog.

The workaround until this is addressed is to use the manual setting and define the boundary of your GROSS Area manually. You might have to do that in any case as different authorities or standards bodies will define GROSS area differently. Findinng the wall reference line is a good first step, but not neccessarily the final determinant of your gross area boundary.

Hi Joseph,

Are you using the "Basic Zone Stamp"? If so you'll need to change the GDL code to show the gross SF of the zone. Select a zone stamp, choose File/GDL Objects/Open Object and open the 2D script. Go to line 23 which reads:

roomAreaStr = str (areaFormat, ROOM_CALC_AREA)

and change it to:

roomAreaStr = str (areaFormat, ROOM_AREA)

and save your changes. If you aren't using the Basic Zone Stamp chances are the problem's the same, it was programmed to show the net area or calculated area and not the gross area of the zone.

Steve,

That's one "insert miracle here" closer to finishing the day. Thanks!

You can use the zone polygon menu to select the gross or net floor. What I havent been able to determine if there is a global variable to determine if the zone is GFA or net. This would be useful because the text GFA or NET could then be applied to the zone. Any ideas?

This gives the calculated area (whatever that is as it appears to be effected by the elevation)

roomAreaStr = str (areaFormat, ROOM_NET_AREA)
gives the net area (area to edge of zone boundary)

I've uploaded the incorrect functionality for the Gross alternative as a question to GS support.
I'll get back with the answer here, when received from GS
