Break one or more lines at intersections with other lines.

The Multiple Break AutoCAD routine from Ferdinand Gawat enables you to break one or more lines where they intersect with other lines. You can specify a distance to break the lines, or specify 0 (zero) to break with no gap. Start by loading the LISP file, then type in the command MBreak. Select one or more lines as the cutting object(s), and then select one or more lines to break. Although the code does not contain comments, it is well laid out and easy to understand. Note that this routine only works with line entities.

Great tool. Let me know if you can break a line with an object i.e. insert a hand valve on a line and this breaks the line.

Tom, do you need the actually broken or do you just need to hide it under the valve? If the latter, would a wipeout in the block work for you?

IF YOU USE FRACTIONS OR FEET & INCHES, be sure to enter the gap size as a DECIMAL or INTEGER value. Because of the way it handles the gap setting, if you enter, for example, 1/8 or 1'4 (valid inputs under Imperial units), it will use a gap size of 1. Enter (in those cases) .125 or 16 instead. [Or, re-write the code to use (getdist) instead of (getstring) and appropriate subsequent adjustments.]

Great tool. Is there anyway to modify it to edit polylines?
