Hi everyone, first post.

Currently working thru the Apache tutorial, and just got some odd results.
Have backtracked but can not figure out what is causing it.

I am about 10mins into part 4, and trying to split the recessed (rotor housing) opening, to get a sharper edge.

Problem is, when I hit 'enter' to complet the split - I get the unexpected spiky geometry.

Anyone have any ideas ? - I'm sure it will be obvious to more experienced users, but its driving me mad :headbang:

Any help much appreciated !

Sorry, forgot to include images, off to work out how to do this
