I'm trying to trim the green lines to the blue line, and extend the green line to the white baseline as shown below (first 3 between 0+00 & 0+10). Usually this is a very quick task using the TRIM/EXTEND LINES command with the "Multiple lines to bounding lines" option with the "select by layer" or "select similar" selection method. However, the selection set is lost when you go back to the command. Wasn't there previously an "OK" or "Apply" button at the bottom of the layer selection screen? Unfortunately, I now have to do each line individually to finish which is disappointing to say the least. Note: the command line helps but it's no where near as convenient as being able to select multiple lines by layer or similarity. File attached.
