• 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.

Filter syntax

hi Arno
After almost 2 years I decided to get back to my hobby scenery creation. I'm so happy now that SCENPROC has CREATEAGNLIBOBJ, it does help precision place stuff.

One quick question is related to filter expressions. Let's say I wanted to filter based on modulo operator (%) to get some different GUID for different points, is that possible at all? Or should we do all the computation in the DBF and just leverage that?

On a side note, what DBF editor do you recommend? I find that it is not possible to edit DBF III files in Excel any more :-(

Thanks in advance!

Arvind.
 
Hi,

At the moment the filter only has the operators list in the manual. That's basically equal, not equal, bigger and smaller. Also when you specify multiple conditions they must always all be true for the filter to pass.

It's on the wishlist to make this more flexible, by also allowing or conditions for example. I can also add the modulo operator, should like a good addition.

What you can do however is use ADDATTRIBUTE to add a new attribute where you do the selecting. You can then use that attribute to assign the GUID. This still won't allow using modulo, but might make things easier.

I usually use QGIS if I want to edit attribute of my vector data. But if I want to edit only values in a DBF file Excel is usually the quickest way to do it.
 
funny you guys brought this up
i was just thinking yesterday that it would be nice to have scenProc list the features
but i was thinking for OSM file

i do the same in QGIS, there's a useful plugin for that; called table manager
makes it very simple to edit
