lisp autoload

contact lost

I recently imported some autocad menus and toolbarsinto IntelliCAD.I found that the lisp 'autoload' would not work.This is despite the fact that it is included as a viable lisp function in the help tutorials.I replaced the "autoload" with "load" to load the required lisp files and had success.Also I was interested in how IntelliCAD stores the lineweights when importing AutoCAD 2000 files so that they can be resaved. I used lisp "tblobjname" funtion" to read a symbol table for layer only to find that dxf group code 370 for lineweight is not supported. Does any one know how to read the lineweights within IntelliCAD.

You must put this code in your Icad.lsp to have a working AUTOLOAD:;AUTOLOAD and AUTOXLOAD implemented in LISP;by Ronald Prepchuk, Visio Corp.;Creates dummy commands which load the appropriate file and then execute the real command(defun AUTOLOAD (Filename CommandList)(foreach CommandName CommandList(if (/= (substr CommandName 1 2) "C:") (setq CommandName (strcat "C:" CommandName)))(set (read CommandName) (list 'nil (list 'load Filename) (list (read CommandName))))))(defun AUTOXLOAD (Filename CommandList)(foreach CommandName CommandList(if (/= (substr CommandName 1 2) "C:") (setq CommandName (strcat "C:" CommandName)))(set (read CommandName) (list 'nil (list 'xload Filename) (list (read CommandName))))))
