This would be a case of think like a carpenter. The carpenter doesn't need the hole to exactly fit the sink, the sink just has to fit in the hole and since it has a return around the top edge, it will cover the parts of the hold that don't match the sink. The lazy man's way: First, hide the sink. Double click on the top until you get through the different groupings to where the top most surface is highlighted. Draw a rectangle on the surface of the top. Push pull the rectangle through the depth of the top. Turn on Hidden Geometry under the view Menu without exiting the sink top group, you will now see the ghosted view of the sink. Using the move tool or the push pull tool, move the sides of the hole until they are under the apron of the sink edge. Once that is done click out of the group, right click on the hidden sink and unhide it, turn off the hidden geometry under view and you are done. This uses very little geometry and represents what the carpenter will really do (they may put a radius in the corners but not always). Hope that was clear.

Cheers Dave Means alot coming from a talented SU guru like yourself. I have had some success with some models using the materials we discussed but I am busy learning SU the hard way - (making mistakes and trying not to repeat them) as I really want to do good NPR and ultimately PR renders to blow my clients away. I think a 2 year timescale working everyday to improve will get me to where I want to be. Thanks again for the comments. Slainte Dermot

I cannot add too much to the practical ways of compression - every image editor has its own way to do it (mostly with some kind of a slider as Pete suggests). As for interlacing however; you won1t need it. It means that when it's displayed in a web browser, it first displays a "reduced resolution" version until the whole image is totally loaded into the cacje of the browser and gradually "refines" the resolution of the display. So basically that setting is for large file sizes (which would take a while to load) on one hand and for internet use on the other. Interlacing will add some Kb's to the file size but useless in SU otherwise.

Welcome Dermot. My only additional advice would be to watch all of the GSU training videos (if you have not already), some of them more than once. http://sketchup.google.com/training/videos.html
