Double subtraction

[sn]

Does the geometry builder correctly support subtracting two (overlapping) objects from a third?

As a test, I tried to build a segment of pipe that can sit on a second pipe at a 90* angle.

To form the pipe, I took a cylinder and subtracted a smaller coaxial cylinder.

Then I took a third cylinder, rotated 90* from the other two, butted it up against the above, and subtracted.

(Actually, I did the steps in the opposite order, subtracting the pipe lumen last, but this way is easier to visualize.)

The first hint that something was wrong was that in 3Dtin, the pipe lumen only showed up when looking down from above. When I viewed the object from the bottom, the lumen disappeared.

When I exported to a viewer, the pipe lumen was not present at all.

Hence my question -- does multiple subtraction work completely?

Hi,

Did you save the sketch? Can you post link to it, so I can see what result you got? It's possible that the geometry kernel created incorrect result for boolean operation. But what you want to do is supposed to be doable.
