Finally. The baby has arrived. hrail.lsp that is. A difficult birth, accompanied by much wailing and gnashing of teeth. Just as well that I was forced to take some days off work, otherwise it might never have been done. Last weekend it was "finished", that is until I tried it out on a real drawing: it crashed and burned when the pline had an elevation greater than 0.
I'm quite surprised that I managed to debug it today and get it ready to roll. It was a neat feeling to see it doing it's thing in the end.
Which makes me wonder why I should spend my limited time left on planet earth doing stuff that I end up giving away for free? Probably just mad. Seriously, I have wanted one of these for years now-and if nobody else wants it, big deal: I'm going to get a lot of fun out of using it.
It's a bit like someone doing crosswords-just a bit of a challenge and exercise for the brain, and if someone else gets some use, good.
It makes use of a dialog box, offering use of 6 different types (see the previous blog). The idea is to draw a pline CLOCKWISE around the floor edge of your steel platform, issue the hrail command, make your choices, and pick the pline to get the results shown above.
I'm making the files available only by email request to gauge if anyone is interested.
