I have a shapefile of conifer trees in QGIS 3.16 that I exported as dxf and opened in Global Mapper. In QGIS, the area covered by conifers is easily recongnizable with the blue color as in IMG1. In dxf format, only the lines around the areas are visible, so it is not possibile to distinguish easily whether the tree polygons are inside or outside of these lines as in IMG2. The issue is that when I select an item in the dxf file, it selects all the area of that polygon and not only the separate blue areas as in IMG3. As shown, the white areas inside the big blue polygon are also selected in dxf, while they are no conifers there. Is there a way to visualize the polygons in dxf format as they are in GIS? Can I change something in my polygon so it appears the same as I see it in GIS for my boss who sees it in CAD?
When converting to .DXF, QGIS polygon features are converted into CAD hatch features, and QGIS line features are converted into CAD polyline features. Points are a little more complicated to explain, as it can depend on the symbology used to display the points in QGIS.
It is important to pay attention to the [Symbology mode] setting in the QGIS [DXF Export] dialog. There are 3 choices available:
- No symbology
- Feature symbology
- Symbol Layer symbology
You should likely use [Feature symbology] (try this 1st) or [Symbol Layer symbology] (try this 2nd).
There are multiple dialogs to export .DWG files from QGIS, and regarless of which one(s) you used, it is possible that you had the [Symbology mode] set differently.
