To quote Google... Sketchup requires a 3D class Video-Card with >=512Mb of memory. The card's driver must support OpenGL version 1.5 or higher, and be up to date. Have you looked at your card's control-panel settings - e.g. many to allow 3d applications to take control rather than use presets etc...

@tig said: You should be able to set custom_attributes to whatever units you want... Change the attribute name to say 'myLenX' etc and see if that helps... Post and example and we'll investigate it further... Hi TIG, The problem is not being able to set the units after custom attribute definition. The problem is that it defaults to text. There are times I have to add a custom attribute to a number of components and it gets to be a pain to have to go in and change the units each and every time from "default: text" to "inches". For instance. I have a dynamic cabinet door that initially had a "Rail_and_Stile" custom attribute that was set to "Parent!Rail_and_Stile" to denote the widths of the Rails and Stiles of the door. I came to a point in time when my overall design dictated that I had to have some doors that had 4 different rail and stile dimensions. One each for the top and bottom rail and one each for the right and left stile. Adding the 4 custom attributes to the door definition was no problem. Each variable was then set to "Parent!Right_Stile", "Parent!Top_Rail", etc. Four new definitions and in each case I had to change the units from "default: text" to "inches". All of which was no problem on the door. The problem came when I had to add those custom attributes to each of the parents: 4 times 15 and in each case the units had to be changed from "default: text" to "inches". It would have been nice to have the ability to set what I wanted the units to default to. Cheers, Mike

@danbig said: Have you made any headway on getting unique control over the component copies? Hi Dan, Yes I have. I've attached the new and improved Drawer Cabinet. Take a look at the Component Options and you'll see a number of things that are programmable. Regarding the drawers, it's programmable with 1 to 4 and each drawer is programmable in size. If you use the Interact tool, you'll see each drawer box is different depending on whether it is a top, bottom, or middle drawer. Specifically the top and bottom clearances change. As you can guess, the copy command wouldn't have worked due to the programmability of each of the drawers. I did use selective hiding instead. Cheers, Mike EDIT: Replaced the DRAWER CAB.SKP file with an updated one. Drawer Cab.skp

There are some rendering applications that can export an alpha mask (white for the rendered objects and black for the background). Have a look at Kerkythea for instance (free). Then it's just a matter of multiply layering the images.
