How to delete a surface in an imported object? [w/ screenshot]

Hey guys,

I have an object file of an altar which I got from the google/sketchup database. As you can see in the screenshot below, this object has multiple surfaces. What I would like to do is to delete some surfaces (for example, I want to delete the human figure, the book + stand, etc.). Is there a way to individually delete these items within the single object?

Thanks!

    You are not actually wanting to delete surfaces...you are wanting to delete actual geometry.

    So, open the Geometry Editor tool and select the item in the Scene tab/pane.  Then right click in the viewport and then Geometry Selection > Select By > Surface (if you know the surface names, and for the person, at least 3 are visible in your screenshot).  This will highligh the chosen surface, if it's what you want to get rid of then right click and choose Geometry Visibility > Hide selected polygons.  Then to make it permanent right click > Geometry Editing > Delete Hidden Polygons.  After you've delete what you want, export and reimport the item.

    You have been incredibly helpful. Thank you. Do you also know, once the geometry is deleted, is there a way to remove their properties in the surface editor  (on the right side in screenshot)? Or perhaps that is why you need to export and re-import the object? 

    Thanks again.

    Save it out as a prop asset, then load that or export and reimport it...the reloaded item will not have those included in it.

    Perfect, thank you. And I am assuming, in order to apply iRay shaders (such as gold plating to candle sticks), these sketchup objects first need to be UV mapped.... And, to do this, I would need to separate out each individual obect as a separate .obj file, correct?....Unless.... I can UV map the entire object as a whole...

    I cannot tell you how appreciative I am.

    Yes, they need to be UV mapped...and yes you can to the whole thing at once, but it would be 'cleaner'/better to break it up into individual items.

    If you've got all those surfaces showing up in Studio, isn't it already UV mapped?
