redefine open command

[kw_friday]

I have rewritten the open command and would like Autocad 2015 to use my command. If, however I don't start in a dwg my code will not load(I undefined and redefined "open" in acad.lsp). Once a dwg is opened then my code is active. How can I force my open command to be the only one used?

Hi,

In zero document state you have very limited options, this link may help: ZDS

add your code to the ACAD2014doc.lsp file as part of a s::startup function. This one loads with every drawing (instead of just once on opening AutoCAD) and works nicely for similar things on our end.

You should create / use "acaddcoc.lsp" to apply to every document.

acaddoc.lsp does not exist in an OOTB install (it will never be overwritten by a re-install).

Check help (search "acaddoc")
