Little noob question for you guys.

I'm using 3ds max 2009. I need to make some boolean subtractions, but the resulting object displays some imperfections in the near of the hole I've generated (the surface doesn't appear to have the same smooth as before the operation, there are some lines and the polygons aren't perfectly in place).

I've tried to had a cap hole modifier to the object that will be subtracted, I've tried the pro boolean and the turn to poly modifier with the "keep polygons convex" option and tried to add some more polygon on the surface that will be cut but I can't have a perfect result.

Any ideas?

Hope you will understand guys. Sorry for my bad english.

Thank you

Don't worry about the english, I think its pretty good wink.gif
mhm, can you post a screenie of the resulting boolean, its mostly not advised to use booleans cause they always create tris and deformations.. I think you've already tried turbosmoothing the surface and collapsing the stack before doing a boolean which will help to keep the geometry as precise as you want after the boolean operation?

Thank you for your answer!
Yes, I've used the turbosmooth modifier before the boolean. Sorry, but I don't understand what you meant with "collapsing the stack": I'm a newbie of 3ds max, I don't know all the functions of the application yet...

Anyway, here's the screenshots. The wireframe version:

And the rendered one:

Ok, I know, it's pretty good. But that's the best result I could have after several attempts, and I'd love to have a perfect one.
Can you see those imperfections around the button locations (it's a psp, by the way, I haven't deleted the polygons yet)?
I know that boolean operations could produce some imperfections, but I don't know any other ways to ad a hole on a curved surface...

EDIT: sorry, I don't know how to add the thumb previews of the images

No need to be sorry for it, neither do I know how to do it, haha!

You can probably do it like this, this may not be the best method lol

Uhmmm: looks very interesting your technique! The result is exactly what I need and I'll try it for sure!
The only problem is that with my technique I use the shape of the button lightly extruded for digging the hole. So I can create a nice border that fit perfectly with the button. In this way:

(I've highlighted the border in red).

But you're technique seems pretty nice, so I'll try it.
I'll let you know.

Thanks a lot for the help!

I see, well you can detach polygons and then extrude them to use them as buttons if you want, this you already know probably, goodluck with the outcome, I hope it turns out good grin.gif
No problem mate, anytime!

Yep, I've thought at that solution.
Thanks again for your help

My method of doing boolean sub is:

cut new edges around where the bool edges will be, sort of roughing it in
then use the Pro Booleans plugin to substract it as normal.

I've been able to cut some fairly complex shapes with this method.

Sorry, I didn't completely understand...
You just add some edges on the surface that will be cut with the cut tool, right? You add it by following the edges of the object that will cut the other?
For example, here's is my project:

I'd like the cut the surface of the psp (yellow) following the shape of the two buttons (brown). Can you just explain in a few words how would you do that with your technique?
Thank you

Pictures worth a thousand words. This is where I'd cut before applying the boolean: (see image)

Ok, now I see.
Well I'll try your method and see what I can get of it.
Thanks

Thank you so much for your help.
In fact, I've already found a different solution, but I'll try for sure your method. Seems very useful.
