Let's say I download an OBJ and want only one part of it

and that OBJ has several parts. Unfortunately, it has no other things to click on in the scene tab. No leg, no arm, no thing. But it's an OBJ that has an arm or a leg or a head or whatever. But let's say I just want the head.

I load it up in Daz Studio. How can I keep the head and delete the unwanted parts?

    Select the Polygon Editor Tool (PGE) from the Tools Menu
    Left click on the part you do not want (This step is just to initialize the PGE tool)
    Right Click to get the PGE tool option menu up. This is where you can choose how to select , hide and delete polygons.
    Depending how the model is made up might be able to click on one poly and use Shift + Ctrl + + to grow the selection, otherwise it will be manual selection only.
    Once you have all the polys selected right click and I think (without looking as I have a render going) the Delete Hidden Facet command is in the second from the bottom in the PGE menu.
    Accept the selection and you are done. This will also keep uvmapping intact.

    Thanks, Szark! I'll give this a whirl. If I encounter any problems, I'll post them here. :)

    If the object is already divided into existing material zones exactly where you want, you can simply go into the Surfaces(color) tab and set the Opacity parameter to 0 for all the pieces you don't want. It's not efficient since the whole object is still there, but it's the easiest option.
    If for some reason you want to get rid of the other pieces of geometry altogether (perhaps for performance or memory limitation reasons) and you have Hexagon or some other modeler, you can use that modeler as a hacksaw to just chop off the piece you need (ie, delete all the polygons you don't need) and then bring just that piece into the scene. However then I would assume you would have issues with the material, and obviously issues where the missing polygons leave holes. However I have done this where I was going to apply a shader to it and wasn't going to use the material anyway, and the cut end was facing away from the camera.
