Thread: Issue with 3dc files - Serbia

Here is what I think happened, if you renamed a .3dl to .3dc, it will only show the "property" of .3dc which is simple polygon (or in your case, just the footprint)
It's not a licensing problem, it's a type problem. .3dl files should not be renamed as .3dc and vice-versa.
What happen if you only use one .3dl at a time? You should not see the "footprint" problem.

Update: Renaming .3dl to .3dc will cause licensing* problem on NextGen and won't displayed it. BTW, you can create your own landmarks

* it might behave differently on Primo since licensing is handled differently. What Primo version are you using?

That is all that exists, for years.
There was one older petrol file, but smaller, so nobody uses it anymore.
Also, from both other providers, there never was made 3dc file.

Spoiler: .

The .3dc contained data to draw simple polygons using share texture or just colors. That is the texture exists externally and are shared (or in case of no texture, just color)
The .3dl contained data to draw complex polygons with it's own textures. That is the texture data can (and generally is) given for each surfaces.
You should not renamed the extension, it will cause unpredictable behavior. The coords was extracted via my proggy and doesn't reflect exact location of the objects. The .3dl data is complicated and I did not parse entire thing, so I do not know if there are adjustment to those coords. Also I do not know if .3dl actually store the landmark names (and some how you got it to displayed in your proggy)
The "behavior" is different for NextGen vs your Primo proggy. For NextGen there is no problem (no footprint) AND no name of landmarks. I currently don't have access to Primo to test, but my gut feeling is that either you have a hacked version that behaved that way or there was config setting somewhere that was done to get the behavior you're seeing.
I think you'll get much better help in understanding your problem if you contact people in the Russian forum.

Thanks. I got it now.

Out of curiosity, I've checked with genuine Hungarian Here 2017 3dc and 3dl. Here is the result, exactly as per your explanation.

First one with primo:

If I zoom/rotate, most of red footprints transform into buildings.

Second one with NextGen:

Conclusion:

As @boki confirmed, initial Serbia NNG file wasn't 3dc at all, but 3dl. Someone, somewhere, renamed it and it used to work with different extension, until update. Apparently, all information is currently showing as landmarks with full texture, since I can't recall ever seeing grey buildings, as shown on original 3dc. Merging two available 3dl for Serbia gives most complete data.

Only thing I should investigate more are footprint. Not that it bothers me much.
