I'm having trouble importing sweep paths into C version 1.1. I'm following the instructions on page 161 in the reference guide, but when I click "open" (step 4) no dialog asking whether I want a sweep path or envelope comes up. Nothing apparent happens at all. The steps I take are: 1)Draw circular cross section in spline modeler. 2)Center selection. 3)Set ext. envelope to symmetrical. 4)Click on Y axis drawing plane. 5)File>Import> select an eps file that has only a 90 deg line with a small radius. (I created the file in Freehand and have also tried saving it as an Illustrator file). 6)Click open. The import dialog goes away, but nothing else apparent happens. I'm trying to create a pipeline with clean 90 degree elbows. Am I missing something here?
