[LDCad] Simple LDCad script

[N. W. Perry]

Minor potential bug:

Code:

local cnt=sel:getRefCount()

will cause a runtime error when no model is open, easily fixed by moving the line (and the one above it) below the ses:isLinked() test.

Fixed. Couldn't I also move the local variables col and ref up higher somewhere, so I don't have to repeat them?

My next attempt will be a macro to comment out BUFEXCHG lines. I think I know how to identify the affected ref lines, now to learn how to actually alter them. :-)
