AnchoredSnapper - No anchors

Hi,

I’m processing CAD-files in a script and my mission is to repair them to some limit. In one section I’m using the AnchoredSnapper to snap one type of lines to another type of line. Using the AnchoredSnapper bc I need the first set of lines to not move. Worked fine with the first file I ran, but the second time I ran the script with another CAD file, which didn't contain the type I set as anchors, the AnchoredSnapper processed the lines as I was using the Snapper instead, ie snapping the candidates to eachother. My expectation was that every input would pass out through the untouched port since there were no anchors to snap to.

Is there a reason for this? How can i solve it?

Best Regards, Anna
