I'm using QGIS 3.8 and I've got two shapefiles which I would like to cut in pieces using Split with lines

Both times I used the algorithm the first two lines did not cut through my shapes, while the rest of the shape is properly cut in pieces.

Is this is a bug that someone else has experienced?

Here are some pictures of my problem:

    Please Edit the question to include Well-Known Text for the polygon and the first four lines for at least one of your diagrams

  • @Vince I do not fully understand what you would like me to edit. Could you please elaborate your question.

    Well-Known Text (aka WKT) is an ASCII representation for geometry. If you include the geometry in the question, others can review the data and attempt to reproduce your issue.

It's quite likely to be a bug as I have experienced something similar, I would suggest you post a ticket on their GitHub page.

In the meantime, a possible workaround is to dissolve your line layer so that it contains a single line feature and then use this with the Split with lines tool.

  • This did not help me... 1 line, 1 polygon, same CRS, complete intersection. No error message, no cut.
