In addition to being able to connect multiple objects together, Curves on…Surface can also be used to cut holes in object--in other words to trim away…parts of a NURBS surface.…Now we saw some of this when we used the NURBS Planar tool, where we created a…curve and then trimmed away those parts that weren't in the curve.…Now we can do this a little bit more precisely using the Trim tool.…So I've got this basic submarine here and if I hide my Sub layer, you'll…see that I've got my reference and we have this big window in the side of the submarine.…
So let's go ahead and use the Trim tool to create that.…I am going to go ahead and turn on my Sub layer and let's go ahead and draw a…circle that's going to be the same size as that porthole.…Now I am not going to do it in the perspective window;…I want to go into my side view here and make sure that I have Hardware Texturing…and X-Ray turned on so I can see through model.…So let's go ahead and create a circle that matches this diameter, so I am…
