selecting a named surface after drilling

[3dinfog]

beginner question... I'm doing the cordless phone tutorial from 'essential lightwave' book and in order to show the joint between the front part of the case, an the back, I've drawn a polygon representing the width of the space between the two halves, then drilled it into the case using stencil, and giving the surface it makes a name. the problem is that when I select the name in the stats window, LW not only selects the joint, but also some random polys around the joint (screen cap included). not sure if its a LW bug or me. thanks for the help, and thanks for a great forum!

Not sure why that is, but you can just select those unwanted polys and re-set their surface back the way they were before. This will let you select that divider surface correctly. Maybe it had to do with the way the drill operation happened?

Yeah, I kind of think so. Sometimes you get random things with the booleans. One thing that can eliminate these kinds of artifacts - if you will - is to select the polys you want to drill instead of the whole object. This way there is less to calculate.

One of the things that I do is make sure that the geometry that I don't want to stencil is hidden, in your case the front and back of the phone. Stencil can intersect things weird and cause random things like this. Either this approach or Surrealist's limits the amount of geometry that the operation is working with and can limit these errors as well.

So this is why the Speed Boolean is much more prone to errors than the normal boolean tool? Because it's calculating the entire model?
