Q - question

Export coordinates of intersection points.

A - answer Using a combination of freeware tools you can easily schedule and export XY coordinates of all line intersections in a DWG drawing.

You will need the tools INTLINES and P2BLK (see Download), plus the dynamic label block PtLabel (see Blocks). Load both downloaded LISP utilites with APPLOAD and insert the block PtLabel.dwg into your drawing.

Then start a combination of INTLINES and P2BLK commands, optionally followed by DATAEXTRATION (of course you can also extract the points alone).

See the detailed procedure in the video:
