Section by Line
Creates a section perpendicular to the current view, by defining two points. This is the default option.
1. Select Section by Line (2 Points) from the local menu or Inspector Bar.
2. Select the object to section. You can use Shift to select more than one object, or use a selection window (first click outside the objects, then drag the window).
3. Select two points. The section plane will pass through the line defined by these points, in the direction normal to the current view (into the screen).
4. The section is created, but in the current view it appears as a line.
You can rotate the view to see the section.
