where are in-built lisps saved to?

[barry2104]

I can type in a command "MIDDLELINE", then click two straight lines, and a new line will be drawn at the midpoint between these lines (e.g. two pipe innerdiameter lines 1m apart, parallel, I can easily draw a "centreline" of the pipe). Also works for non-parallel lines - e.g. two lines 90° L line (don't even need to be adjoining) will result in a 45° line.

If trying it on polylines, it will first try to convert the PL into a normal Line, and then I'll have to rerun the command to get the middleline.

what I want to know though, is where this function is saved. Not even sure if it's a lisp, because I can't see it in my APPLOAD dialogue. There's numerous other lisp-type stuff that I can use at work but nowhere else. Where might they be saved (and what might they be saved as)?

I would guess the most likely thing is that it is one of multiple commands defined within a single file that would appear in the APPLOAD Loaded Applications list.  That file may not be something you can edit [e.g. .ARX].

If you can't fix it, for something that does the same thing without needing to Explode a Polyline, and also works with just about any two straight entities or sub-entities with linearity [Line, Polyline line segment, Xline, Ray, straight-format Leader, Dimension extension or dimension line, Image or Viewport or Tolerance edge, etc., or any of those nested in a Block or Xref], go here:

thanks for the response, Kent.

I don't have a problem with the lisp, I think it works quite well. I was just wondering where it's stored and whether I could copy it to a USB stick to load onto my home PC (or future companies), or share with the world (anonymously)

I think i found where it is/they are though, in the APPLOAD list on the btm left... there are a huge list of files here with their file location in the 2nd column. Some are are greyed out and some are normal/black. Most of the .arx and .dbx files are black - though upon finding them in explorer, I don't seem to have the program to open them (text editor just shows a bunch of foreign characters).

examples of the files listed here are

   AcApp.arx

   acauthenviron.arx

   AcBlock.arx

   acdgnio.dbx

....etc

If it's in an .ARX file, you can't edit it -- see, for example:

http://forums.autodesk.com/t5/Visual-LISP-AutoLISP-and-General/decompiling-ARX-files/m-p/891694/high...

But you could presumably copy the file to elsewhere, if that doesn't violate your software license.  However, the challenge would be to determine in which file that command is defined [if there isn't some obviously related file name], since you can't open them up and look for command names inside them.  Maybe you could temporarily remove one at a time from its filepath location [keeing very careful track of what you're doing, of course, and putting it back afterwards], and start AutoCAD again, repeating with different files until the command doesn't work.  [You could do the same by temporarily changing a file's name.]

And, by the way...  "I don't have a problem with the lisp, I think it works quite well" ... except, as you mention in the first post, when you try to use it with Polylines.  That's why I suggested the CAD Tips link -- the BI command defined in Bisector.lsp there works with anything that's straight, including lots of things you'd probably never want to use it with, like Wipeout edges.
