Boolean problems
 

i saw philip's tutorial on the layout ui and it describes how to use boolean to cut out of shapes. anyway i have this problem with my nissan z where i can cut the parts i need
the union, intersection, and add boolean work but the substract tool doesnt. Is there something that i have to do to achieve the subtract
here is a pic of what i want to cut out

It looks like you've got the shapes in a background layer as you should do so that's okay...and presumably the background layer object intersects with the foreground layer in the shape you want to subtract? Have you tried moving the objects in the background layer around a bit - sometimes when I have this sort of problem, then if I move the objects slightly, then subtraction will work. It looks like its all set up okay though.

Looks to me like you plan on performing this subtraction on a supatched object. Using boolean operations in this case will cause you a ton of headache.

The reason is subpatches can only contain three and four point polygons. When you perform your subtraction you will be left with a large number of n sided polys.

The best way to make those holes is manually. Drag the points around on your surface to form the shape you need and delete the uneeded polys.

to rich_is_bored: do u think if i got rid of subpatch and then try to boolean subtract , would the boolean then work??

Are you doing each hole separately or trying to do both at once?

If you do them separately it should work. Just be advised that you will need to rid your mesh of any 5+ sided polys after the operation.

i am doing them them both at the same time....im not supposed to do that am i ?

Yeah, you can't do them at the same time. Lightwave doesn't like that.

thanx
