Where to put your (autoload) definitions?
* Not to ACADR13.LSP. * Well we recommend putting it to an initialization file of yours and not to ACAD.LSP because this is often changed by different applications and ACAD.LSP should be kept rather small. I.e. put it to a AUTOLOAD.LSP or INIT.LSP, which is loaded from ACAD.LSP. See “[11] My LISP doesn’t load at startup anymore” * It should be mentioned that users should *not* modify ACADRxx.LSP. Since ACAD.LSP is not overwritten during upgrades, it is guaranteed to remain safe. In addition (as we saw with the R13c4a patch) if the ACADR13.LSP file has been modified, then the patch process may refuse to update it, thus resulting in program malfunctions.
