Hi Gilberto,
I've just watched Kris's screencast and she does press ENTER on the keyboard after specifying the end point of the section line (at approx. 34sec). I'm not sure if this is the step you are missing, so here are the steps based on the timeline --
1. At 25sec, Kris launches the Section View command.
2. At 27sec, the parent view is selected.
3. At 29sec, a midpoint is acquired by hoverring over the view's geometry. This allows the section line to be drawn along the center of the component.
4. At 31sec, the section line's start point is specified by picking a point.
5. At 33sec, the section line's end point is specified by picking a point.
6. At 34sec, Kris presses ENTER on the keyboard to complete the section line creation. Alternatively, you can right-click and select the Continue option in the marking menu (just like you can in Inventor).
7. At 37sec, the section view preview appears and is attached to the cursor. Depending on the model, it may take a couple of seconds for the preview to appear.
8. At 38sec, the section view's location is specified by picking a point.
9. At 40sec, Kris clicks the OK button in the VIEW PROPERTIES dialog to complete the section view.
10. At 41sec, the section view is complete, hatching is added along with a view label.
I hope this helps, and please let us know how it goes.
Thanks,
