Checks if (majorRadius >= |minorRadius| - OdGeContext::gTol.equalVector()), creating a solid with a hole in the middle.

true if and only if (majorRadius >= |minorRadius| + OdGeContext::gTol.equalVector()).

Exactly one of the following functions will be true for a given torus:

• isApple()
• isDoughnut()
• isLemon()
• isVortex()
