Block-Path is a routine by Raymond Rizkallah that allows you place blocks along multiple objects simultaneously. It's similar to the built-in AutoCAD command Measure, with two distinct differences. First, you can work with multiple paths like polylines, splines, ellipses, circles, etc. The second difference is that the routine will ask you for an approximate distance, and it calculates a best-fit distance so that the blocks are evenly spaced along the entire path. For example, if your path is 105 units long and you supply a spacing of 10 units, the blocks will actually be placed 10.5 units apart so that there is equal spacing between them. Start by loading the LISP file, then type in the command NDV. Enter the block name, select as many entities as desired, and supply the approximate distance apart. Nice work, Raymond.
