I'm very new to SolidEdge, and am very impressed so far - thank you!
One thing I can't seem to do is to create a curved line with an arrow-head at the end. I've tried to find a way to add an arrowhead (which I understand are called "terminators") to a curved line, and to use a connector and try to make it curved, but with no success!
Arrowheads are typically displayed on annotations like dimensions, callouts, etc. Connectors do have the ability to display arrowheads, but connectors are derived from linear segments. You can create a block that looks like an arrowhead and connect the block to the end of the curve.
