Mapper: CRT & DXF

Somebody reported on Sourceforge [tickets:#443]:

Would it be possible to import DXF files with CRT as in OCAD?

What does CRT mean here?
DXF support is rather basic.

CRT = Cross Reference Table; basically a text-file defining the transcription from for ex. .dxf layer codes to OOM symbol codes.

Must useful to repeatedly import the same type of data (for ex. OSM-data)

This is related to several tickets regarding DXF import and the ability to read CRT files is a very missed feature.

This would be useful. I have such mapping for free-to-use data from National Land Survey of Finland. Might write a short howto + improve the existing tooling (eg. shp-to-dxf converter, coordinate system stuff, ...) for using that data with OOM. All the related DXF import improvements will help on that.

About the CRT file I have:

it has two columns, apparently ISOM code and the second value is the DXF code
some lines are missing the first value: maybe this means "ignore", or maybe it's a mistake in the file
not sure where I actually got this file, need to figure out...:)

Note: There is no file-open dialog. Mapper looks for a CRT file with the same base name as the DXF file while doing the import.

@dg0yt, is it possible create functionality for use tags info for first column (as on this screenshot) when import DXF/OSM? (without need CRT)

Currently using only Tag Selector method its need much time for converting objects with each tags to needed symbols.

@Symbian9 It is possible to implement but noone is working on it. And is out-of-scope for this issue here. Your request seems to belong #606.

New 1:10K ISOM map
Import rotnes contours, skip CRT mapping the negative contours
Map georeferencing:
UTM 32 N coordinate, keep geographic coordinates
Show UTM coordinates in lower right status field
Save as rotnes.omap
Import rotnes vegetation, keep suggest CRT mappings

[OpenOrienteering Mapper 0.6.20170128 has stopped working]

When I then click [Debug] and go into VS2015 I get more detail:
Unhandled exception at 0x000000000052FA31 in Mapper.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

I.e. from the low address this seems like a NULL pointer being passed to a library routine somewhere.

OK, getting closer possibly:

Opening the attached vegetation file crashes immediately:
rotnes_vegetation.zip

True. It is trying to render an object which has got a null symbol.

New unstable binaries are now available.

Using windows 0.6.20170130 I was trying to import a DXF with a corresponding CRT file in same directory. But nothing happened. Just 'normal' imports, no popup to map symbols. I also tried Terjes rotnes_vegetation.zip. Here I get a message about an empty folder, nothing to import.
