I have two QGIS layers. Layer 1 has a floor plan with an attribute field holding feature types, e.g., wall, corridor etc. Layer 2 consists only the lines drawn between door centroids. I want to query the lines in Layer 1, which cross a wall or corridor from Layer 2, then delete these lines.
How would this be done using QGIS?
This is what I have:
and this is what I want to have:
With a virtual layer (official documentation), you can create a new layer then save the result as :
SELECT lines.* FROM "Layer 1" lines, "Layer 2" structure, WHERE NOT( structure IN ('wall', 'corridor') AND ST_INTERSECTS(structure.geometry, lines.geometry) ) or in QGIS create a selection in Layer 2 with an expression like type IN ('wall', 'corridor'), select all features in Layer 1, and with the tool select by location (documentation), you can remove selection from Layer 1 that intersects selected features in Layer 2.
Then, toggle edit mode in Layer 1 and delete selected features.
