Bad Argument type FILE: nil

[rcardozo]

A Client sent me an updated template file. I have an autolisp routine based on expresstools blockreplace command. Now when I try to run the command I get the message, "Bad command type: FILE: nil". The funny thing is that nothing has happened to the command and blockreplace still works. I can't see how a file can affect a lisp commands ability to run.

I know this is a late response to this post, too! :oops:

But anyway ....
A file can affect a LISP if a LISP looks for particular blocks or tags.
And if certian tags or other elements are corrupted by 3rd party softwares then errors will occur.

Not sure if this is a solution but see the is post clean it up.
