After countless requests to post an article/tutorial on how to correct this problem, I have finally managed to put something together with help of a prolific script writer/ senior Visualiser/Photographer called David Venables.
David created a simple script to override the above mentioned problem!
Without further ado let us start by importing an AutoCAD file format (i.e. DWG) into 3Ds Max.
Next, press “Ctrl+S” to save it as a *.mcr.* file format in an accessible shared location.
In the “New Toolbar” dialog, name it accordingly and “OK” to close the dialog. A new toolbar button should automatically appear.
With the new toolbar button created, one can now close the “Customize User Interface” dialog.
An image button should automatically appear in the newly created toolbar.
The “Edit Macro Button” dialog should open. By default it is set to “Image Button”.
Finally, close and restart 3Ds Max. The newly created toolbar button should now be visible/part of the main toolbar.
To test whether the new toolbar is working or NOT, import a completely new drawing into 3Ds Max.
Next, reselect the entire drawing and add it to a completely new layer as previously done.
As one can see:The drawing's original colours remained intact when added into a new layer...which is a clear indication that the new toolbar button worked as expected!
Tip: Adding a “#” before the layer name will ensure the newly created layer always stays on top of the list.
