Arc bridges (gaps) in line intersections.

When drawing electrical or process technology diagrams and schemes, you may need to bridge-over line intersections (conductors, pipes) with small arcs, semi-circles.

Besides specialized tools - e.g. AutoCAD Electrical or AutoCAD P&ID - you can solve this problem also with a simple LISP utility CADstudio LineIntArc.

Load the VLX file downloaded from www.cadstudio.cz/download into AutoCAD with APPLOAD and run the command LINEINTARC or simply LIA. Specify the arc radius, gap (can be preset with a LISP variable, e.g. (setq _LIAbrkDis 1.0)) and then just pick the individual intersections to bridge-over and identify the line which is to be broken with a gap and an arc.

The function will keep the color and layer and in case of polylines (LWPOLYLINE) also the integrity of the original lines.
