Well I guess what is better is a personal opinion ... and maybe some problems can be fixed ... just feel it is the weakest modelling tool in AC3D and needs fixing.
Here is a screen capture of a cylinder subtracted from a cube by three different methods (the cross sectional faces ... they all look the same in perspective3d):
1.Red ... A very old version of Truespace (3.2) that was available for free from Caligari
2.Orange ... AC3D using the boolean tool (done with version 5 demo download a few months ago)
3.Blue ... AC3D using a rectangle/ellipse/convexhull/extrude method/trick (by hand)
There is no obvious nice symmetry with the AC3D boolean tool.
And these are the geometry stats :
1. 40v, 60s
2. 220v, 280s
3. 40v, 60s
The truespace/by hand method yield essentially the same results ... the AC3D boolean subtraction is not even close. To me that is not a very clean efficient tool.
As I say, just my opinion, but I think it needs improving.
