• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Since going to the new filter format I get lots of errors with CreateAGNRowHouse. Here is my script code

# create terraced housing
CreateAGNRowHouse|LANDUSE="terraced"

The I get lots of errors:

19:19 CreateAGNRowHouse Information Creating autogen row houses with filter LANDUSE="terraced"...
19:19 FilterEvaluator Error Failed to parse filter: FWIDTH>1 AND FLENGTH>1 AND LANDUSE=""terraced""
19:19 FilterEvaluator Error Failed to parse filter: FWIDTH>1 AND FLENGTH>1 AND LANDUSE=""terraced""
19:19 FilterEvaluator Error Failed to parse filter: FWIDTH>1 AND FLENGTH>1 AND LANDUSE=""terraced""
19:19 FilterEvaluator Error Failed to parse filter: FWIDTH>1 AND FLENGTH>1 AND LANDUSE=""terraced""
19:19 FilterEvaluator Error SyntaxError: Unexpected token "terraced" <IDENTIFIER>; expected one of <EOF>
......

Hope you can help, many thanks,
Peter
 
Check your quotes around the string value, they seem to be double quotes or so.
 
Yes, I noticed the double quotes, but I don't add double quotes in my script (see below)

# terraced
AddAttribute|LANDUSE="residential" AND FWIDTH<30 AND FLENGTH>40|String;LANDUSE|terraced
# create terraced housing
CreateAGNRowHouse|LANDUSE="terraced"
 
The names are case sensitive. You should the first not be landuse for OSM data? And you are overwriting the existing attribute here.
 
The LANDUSE attribute is one that I added from the source:

AddAttribute|FROMFILE="*Building.shp"|String;LANDUSE|residential
AddAttributeIfInside|FROMFILE="*Building.shp"|type="retail"|String;LANDUSE|retail
# terraced
AddAttribute|LANDUSE="residential" AND FWIDTH<30 AND FLENGTH>40|String;LANDUSE|terraced
# create terraced housing
CreateAGNRowHouse|LANDUSE="terraced"

It looks as though overwriting the attribute is adding an extra double quote.
If I change the last line to:

CreateAGNRowHouse|LANDUSE=terraced

then it works. So it looks as though an extra double quote is added every time you overwrite an existing string attribute.
 
That's weird a string attribute value needs quotes. I'll try to reproduce this.
 
Hi,

There was a bug in the CreateAGNRowHouse step. Internally this step filters out polygons with a length or width of less than 1 meter. But I hadn't corrected that code correctly for the new filter syntax. Since I don't use row houses so much I hadn't noticed before. I should add this step to my test script.

In the next development release it will be fixed.
