- I don't think Boolean Add, by itself, will do filleted joints. At least it
- never has for me. But it is a good place to start.
-
- 1) Given your ball-and-pipe example, let's say the pipe runs lengthwise on
- the Z-axis and is centered on that axis as well. This would be helpful
- because some Lathing will be involved.
-
- 2) Looking sideways at the pipe and ball. Zoom in on the area where the two
- intersect. Go to the next empty layer and make the pipe and ball visible in
- the background. Are you familar with using Curves? Create three points on
- the Y-axis that, when made into an open curve, will form a nice fillet shape
- between the pipe and ball. You want an open curve, not a closed one. Allow
- for some "slop over" of both ends into both the pipe and the ball, so there
- will be no gaps in the final fillet.
-
- 3) Once you're happy with the curve, freeze it. See that one long,
- connecting line that forms the flat side of the new polygon? You need to get
- rid of it. Hilight all the points and copy them to an empty layer. Use these
- points to create a string of two-point polygons. Start at one end and keep
- building them all in the same direction (This is important to avoid
- different-facing polys in the final result).
-
- 4) Now Lathe that sucker on the Z-axis. Use as many segments as necessary.
- Lathing or similar operations done on two-point polys result in a whole lot
- of double-sided polys. If you can live with this, no problem. Otherwise,
- hilight them all and then select Unify. This will convert all the polys to
- single-sided. If they're facing the wrong way, they should ALL be facing the
- wrong way (hence my instructions in step 3). Flip 'em and give 'em a surface.
-
- 4a) Those extra slop polygons will be hidden inside the pipe and ball. If
- they are really bugging you though, use Solid Drill/Tunnel, with the pipe
- and ball in a background layer, to get rid of them.
-
- Compared to Alias, it's still a pain in the butt. A macro would be extremely
- welcome, but I'm not smart enough to write one myself.
