Hi Stan, it is possible that this may be a display problem. Try going to Options and check the "Add detail to inflections" button, that puts a bit more detail into creating the display mesh which can fix some of these types of display issues.

But it is hard to tell just from the screenshot whether this is a display problem or a geometry creation problem - if I can get the model I could determine it more conclusively.
