I had a quick go at making an anvil with some boolean ops. I started with the basic cube. Things went OK until I added subdiv mod and bevel and it all went horribly wrong. The bevel didn't seem to do anything and the subdiv made a disastrous lumpy mess wherever it was in the mod stack.
I figured I should have subvided the cube to start with so I tried it all again and the then subdiv worked as expected, my question is: how can I judge what level of mesh detail I need for a particular series of operations?
In this case I subdivided the cube maybe 2 or 3 times, and it worked, (though by this time the subdiv was hardly necessary) but if one has to spend an extended time working on a thing before finding one's mesh is too coarse, I mean it's not very good is it?
What's the best thing to do? Subdivide like crazy and hope decimate can fix it all up at the end?
