I like the idea of making the window-glass and the window-frame separate entities of a Group or a Block. It makes the most sense to me, as it more accurately reflects the real-world-- two different entities/components within one Object.
However, I might have another suitable workaround:
>Make the window-glass thicker than it needs to be, before the 3D-Add. Example: For a window-pane that is to be 48"x60"xÂ½" thick, make it 48"x60"x1" thick (height) for now.
>3D-Add the window-glass and the window-frame. If Materials are assigned previous to this 3D-Add, the first entity to select in the 3D-Add procedure should be the window-frame, so that the resultant Part takes on the Material assignment of the window-frame.
>Right on-top-of the window-glass, create another 3D-Object that has the same width and length as the window-glass, but any height. Example (continuing with the example noted above): 48"x60"x10". Assign the desired Glass Material to that Object.
>Copy that Object to the underside of the window-glass-- facet-to-facet; vertices-to-vertices. (Just relocate the Reference Point to a vertex, pick-up-and-move, Vertex-Snapping to the window-glass)
>Reposition the first newly-created Object to where it is embedded in the window-glass-- in the "height" direction-- that amount that needs to be removed from that side of the window-glass. From the example I'm using: Lower the height of the first 48x60x10 Object Â¼".
>Repeat with the Object on the underside of the window-glass. From the example I'm using: Raise the height of the second 48x60x10 Object Â¼".
>>With "Transfer material from operand..." checked "On" in Options/Preference (or "Off", if it's messed-up/backwards in version-21), 3D-Subtract both of these newly-created Objects from the window-glass-&-frame unit. The result: The glass within the window-unit will have the Glass Material which transferred from the Material setting of the two Objects; and the glass in the window-unit will be the desired thickness-- Â½" in my example.
Works in version-19-Deluxe (attached). Might as well try it.
In version-19-Deluxe, the option is worded "Transfer material from operand". In other versions, the words "on its facet" may be added. So, I don't know how this works with Solids-- that is... if the transferred Material will be incorporated throughout the volume of the Object.
