That quick.3ds is a separate file, right, Doug? How do I get Catalog elements over to it and back?
Yes it is a completely separate program that operates all on its own.
You can export any object from TFP12 as a .3ds object...file/export/as .3ds and name and save to hard disk
(there are a few .3ds objects in the catalog, especially the extra catalogs supplied with the CD)
Be sure to have ONLY the object you want exported as visible (eye open, set all other objects with eye closed...especially don't forget to turn off the terrain or it will be part of the .3ds file too).
Open the quick3D viewer and file/open the .3ds file you saved.
But I don't know why you would want to do that as you can see any TFP catalog object in a mesh or rendered mode in TFP.
The best use for the .3ds quick viewer is to view files that are .3ds (likely on your PC from other uses or considering a download from a web site or forum)...without having to open a big program and import etc. just to make a quick view to see if it meets your needs.
But if you have a good idea why to see TFP catalog objects in .3ds, please share your idea as I'm open to learning something new.
