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 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.
