I just discovered that I can put a line in my lispfile like this: [Some notes]. When I load the lispfile the line is ignored. In other words it acts like comment. Comes in handy because I can use another type of comment, But . . . . . . Do I rely on a rule here or will I get into trouble later when using the code? Thanks in advance, André

Hello Euclid's algorithm: tiling a rectangle (any size) with squares - Can this be done with lisp routine? Regards

Hi guys! I try this http://askjerry.info/weird_gear/ to get a gear of two SQUARE tooth wheels. I have downloaded and installed ACAD especially for the project. For now I could run the script to get a result curve (made out from big white wheel on the left) for primitives (triangle, square, ellipse, etc.) I draw in small red circle on the right. Almost everything seems to be okay but when I try to paste there (to the right red circle) ready made and complicated pattern (tooth wheel) from another CAD software the script goes ERROR. Where my mistake is? Please answer in most common words to let me know you’re interested in further conversation. Then I put more specific and detailed questions. Truly, Alex.

I'm new to AutoCad. I'm trying to figure out a simple way to draw steel tubing which is basically a tubular square with a hollowed out middle, but the sides of the tube all have a certain thickness to it. I'm able to draw the initial square with the fillets on the corners, and hollowed out middle, but cannot find a way to properly resize it to the appropriate length I want to use for my design once I draw it and go to extrude it. Is there a tutorial or video that shows how to create something like this?

Hey guys, We are doing a little chute-work in the office at the moment, and have had the need to develop some bend/folded plate work. The items we seem to be spending the most time on are square-to-round transition segements, where the chute walls are made of 1 plate, folded to the desired shape. Im sure most of you are familiar with this type of work - but I was just wondering if anyone knew of a good routine which will easily produce the developed/flattened plate of these transition segments. We have been using this site... http://www.sheetmetalguy.com/transition.htm... which does work quite well - when it works (it seems the site is quite old, and will only run in IE... sometimes). So i was thinking, it would be great to have a routine which would ask the user to select a 2D square/rectangle and a 2D circle... and the routine would calculate the distance between the 2 shapes (Z value) and then produce a 2D flattened profile of the required shape. Anyone know of a routine such as this? I do have a little LISP experience, but I imagine something like this could be quite involved and over my head. Thanks a lot for any help. Cheers.

I want to draw a square with a line as its side given. I am looking for a rapid solution, like pressing shift while using rectangle command to make two sides equal. Is there any such a short cut for square?
