Thats not too bad,is it what you were expecting?I'm guessing you did a tool change and there may be a very slight discrepancy in the tool length for one of them.For 3D work it isn't uncommon to use a smaller tool for some of the fine detail,but this leaves you with a very long sequence so what I do is to introduce a new layer for boundaries and create outlines around the areas that need the finer detail and use those boundaries to restrict the smaller tool to those areas.Which leads us back to the point about tool length,if it isn't accurate you will have a step to sand out and lose.A tool length sensor is a wonderful thing to have as it deals with the actual tool length-no need to adjust Z datum or introduce errors from a pre-setter.

Odd that only two of us find the topic interesting and nobody else seems interested isn't it?
