Once you have associated an image to a 3D object you will need to unwrap the facets of the 3D object into 2D parts that can be arranged on the image. This will allow you to 'map' which part of the image is to appear on each facet.
The following applies equally to unwrapping ACIS Solids and Surfaces.
You can individually select facets on the 3D object, or select all of the facets.
...
- Select the desired facets.
- Right click and select Packing 2D Part object(s) ...
- The 2D parts will automatically be laid out on the associated image.
- You can un-pack the parts by clicking Packing 2D Part object(s) ... again.
- If you have un-packed you can re-pack by agin clicking Packing 2D Part object(s) ... The second time you pack the arrangement will be adjusted. To get back to the original packing arrangement. un-pack and repack opnece once more.
- When you are done packing right click and select Finish packing 2D Part object(s)...

Occasionally the part and the image will map with an inversed normal. This means the section of the image appears backward on the facet. To remedy this this You need to reverse the layout of the 2D part. Select the 2D part and apply a -1 scale part then use the middle blue node on the edge and drag in past the opposite edge. You can now reposition the newly edges, as long as you do not recross their positions. The edge you select depends upon how the reversal appears, in other words is it reversed along the X or Y axis. You cannot simply scale -1 along the X or Y axis depending upon how the reversal appears. If the Scale options are not in the Edit Bar use the UV Mapping Options to tun them onvia the Edit bar. This will only flip the part but the reversed association will remain. Do not flip the 2D part via rotation. This will only flip as the reveres part but the reversed association will remain.
