I need to convert my line geometry to polylines, unfortunately, exploding the lines and rebuilding them as polylines in grasshopper still yields line geometry as result.
They need to be converted in order for QGIS to read the DXF as a single layer. Regardless of merging layers, QGIS always differentiates between curves and polylines.
Is there an alternative approach to converting the lines? Or should I just add midpoints in between the lines and create polylines from those? There are 11000 lines in the project though and 42000 curves in total (metropolitan scale data).
Ideally, I would just batch convert them using Selline and change the data type from line to polyline.
