I realise that we use Creo in a non-standard way, but one of things that I do a lot is export sketched lines from a drawing into an iges file, and then import that iges into a part, and use the curves in the imported iges as sweep trajectories.
In WF4, this worked well. All line segments stayed as segments, and I was able to use the curves as trajectories. Now in Creo, neither of those is true.
Problem 1) When an iges with multiple lines is imported into a part, if any straight line has intentional breaks in it, the line is no longer broken, rather it is converted into on continuous line. (in WF4 the lines kept the breaks)
Problem 2) Curves in an iges are not usable as trajectories for a sweep. Instead I am forced to create a new sketch on top of the iges curves (by projecting the lines of the iges on top of themselves) and use that sketch for the trajectory. (In WF4, iges lines were usable as sweep trajectories)
I've tried all the options in the import dialog to no avail. Am I missing something?
