Thanks Nicolas. Unfortunately, the problem is not to identify the overlapping lines. I already have a shapefile that identifies the sections with multiple overlapping lines. In this shapefile, for each segment with overlaps, I have the indication of how many overlapping lines there are (at most 3). The real problem is to draw the lines without overlappings. Any suggestion will be appreciated.

My first reaction is to use line offset but the end result is not predictable. You may need to work with Python to do this. You could also probably create a model. If you need to identify the overlapping segments, you can use my Fix Directional Network model 1 to 3. You can download this on the plugin page. https://plugins.qgis.org/models/?order_by=-upload_date&&is_gallery=true The first model will check the Geometries. Test with all default values. After running this model, run the second model. It should identify all partially overlapping lines. This layer will be called "Potential Problem || Overlapping lines." You can open the second model and look at the "Find overlapping lines" algorithm to see how it's done. It should find any overlapping or partially overlapping lines. This video should help you figure things out. https://youtu.be/v61PafSByvM It's not a total solution but it's at least a start!

My name is Antonio Bombonato and it is the first time I ask a question to this mailing list. I have a shapefile with multiple routes (each one is identified by an univoque OBJECT_ID) and some are partially overlapped (i.e they share the same segment). I need to display these routes so they are all visible and without overlapping. i tryed using line offset but some line still remains overlapped. Any idea to solve the problem, possibly using a python script, will be appreciated. Attached the starting shapefile (cables) and the desired result I want to obtain (target). In this case the shapefile target was created manually moving the vertices of each line. P.S. I use 3.16.7-Hannover QGIS version Best regards, Antonio [cid:[email protected]] Antonio Maria Bombonato Software Developer Business Unit Ultra Broadband Italtel S.p.A.
