RE: Subsurface Utilities - Extract graphics fails when selection set created before starting command

Something appears to be broken in the code which determines connectivity between multiple selected elements.  it is not an issue of selected before command or not as originally reported.  The failure seems to be occurring when one element in the selection is backwards direction compared to what would be expected.

Try this:

1. Create 2 microstation lines  headed in the same general direction.  For example, both northeasterly but with a deflection between them.
2. Then create a Microstation fillet between them being careful to pick first line first so that the fillet follows the same general direction.
3. Use the Utility from Graphics commands and it will work.
4. You can even create a complex chain of the three elements and the command continues to work as expected.
5. Now repeat the above except make the fillet go backwards, that is pick the 2nd line first when creating the fillet.
6. Now using the Utility from graphics command, selecting the three elements will fail, creating only the nodes.
7. If you create a complex chain from the three elements, the extraction works but the portion of the utility created in curve will jump from PC to PT.
