I just installed C3.01 and was interested to see that the fix includes some work on booleans. I decided to play a bit. First I made a spiral thread in the spline modeler and converted it to a vertex model. Litst has a tutorial on this at: http://www.chez.com/litst/eng/home.htm in addition to many other goodies.

Working in the vertex room I added a cylinder and made a few modifications to make a blank bolt.

I carefully lined them up, selected them both, did the Ctrl-Alt (pc) thing to select the blank as the boolean subtract object and then did the subtraction. (Construct>boolean>subtraction)

I got this. Not bad, I think, when you consider the things that used to happen in C2! You can even smooth the object without vertexes flying all over the place!

Subdivision

I added a spline model head and while not perfect it's a bolt with a real "cut" thread. I have found other booleans to go much better than in the past and I think this is now a useful modeling technique.

I expect the boolean operations in the Assembly Room are better too, or was it all about the Vertex Moddeler? I will find out as soon as I can. Does anybody have any experience with it already?

I've not fussed with booleans in any of the modelers as of yet but my experience with the general boolean operations are along the same lines. Booleans now work! I have no idea why or what they did to fix this up but it's about 100 times better. I've pulled off boolean operations with C3 which I would have considered impossible before. It's also sort of funny too because I think this was an unadvertised fixed thingymathingy. -Kix

Looking good. Is that a left-hand thread?

I agree, Eovia has done a remarkable job on making booleans better. I made the rounds at Siggraph last year to all the software vendors booths and found out that booleans are a pretty dicey operation for Maya, Lightwave, Cinema 4D and all the other 3D programs out there, regardless of price. the only one that had no problems was Form-Z and that's because it's a solids modeler and all the rest are surface modelers. Carrara also falls into the surface modeler catagory.

great to hear that booleans are working good now,i always searched for some other ways to do my stuff.after my first boolean operation i never wanted to do it again but now i have to test it out too.i heard it too that highend tools have the same probs with booleans,funny.

Yeah, thats a problem with C3, it only does left hand threads. ;-) (Not the first time I've done that either!) Ed
