Is there any way in which you can edit/create the bitmap icons as you can do in AutoCad 2000?

There is no easy way. You can replace toolbar icons with cutom icons, but it requires the toolbar icons to be separate .bmp images in your Intellicad folder.

To create customized toolbars, you can use the same metod that acad used: Create a *.mns file (you can use the *.mns file of acad or create your own) and create *.bmp files.
You can create a new folder for these files if you include this folder to your searchpath.
Check the Intellicad Help for moer informations about the syntax for toolbar customization.

Works fine and sure is a good way to make the use of your system easier, especially if you work with Lisp.
