I am using QGIS 2.4.
I need to import a map I have been given into QGIS to add some ecological survey data.
I was sent a DWG file, which consists of a base map and some overlay data, like land ownership boundaries etc. I opened this using TurboCad, and saved it as a DXF file. I can open the DXF file in TurboCad with no problem, and all looks like it did when I was using the supplied DWG.
To import the DXF file into QGIS, I tried Layer>Add Vector Layer...Source type: file... Encoding: System. When I do this (having selected all three vector layers I'm offered, and the correct CRS) the file opens, but all of the lines are now the same colour and all the overlay information has disappeared.
What is going on, and how might I address it?
