This sounds to me as a kind of advanced GIS tool and a bit of overkill for mapping software. Do you really need to do such operation during mapping? Or...

@ollesmaps If the buildings at least touch, then "Dissolve" ("Rozpustit") shall do the trick. If not, then you need to do what was your original idea: Create "Buffer" ("Obalová zóna")...

Just a little important note about naming of this great future tool: _parallel curve_ or, perhaps better, _offset curve_ seems to be adequate. See https://en.wikipedia.org/wiki/Parallel_curve

I would suspect an incomplete transfer of data from your mobile device to your desktop device. I have experienced this in the past. See #1115 Could you retry?

Hi all, I include here the @gardners 's DXF file enhanced with the GEODATA object. Created with AutoCAD Map 3D 2017. Just to see the difference. [dxf_geodata_example.zip](https://github.com/OpenOrienteering/mapper/files/4401843/dxf_geodata_example.zip) I can prepare...

Here I attach three small DXF examples with just one polyline. Three pairs of drawings -- one in WGS84 (EPSG:4326), one in S-JTSK (EPSG:5514) and one in UTM 33N (EPSG:32633)....
