Changing the Section definition

Custom Section Definitions

Some basic principles about section views:

  • The section line or plane is defined independently of the view direction. You can view a section from any angle, or you can fix your viewing direction and rotate the section, or you can lock the view direction so that it is always perpendicular to the section.

  • There is only one section definition applied in each section view. It doesn't matter which section line you are currently viewing, when you change the section definition, the change is applied to all section lines in that view.

  • The number of sections lines is dynamic and is recalculated by the program whenever the section width is changed so that the full extents of the data perpendicular to the section line are included.

These might be in a predefined, non-parallel pattern such as a fan or they might not have any specific relationship one to the next. You can change the section displayed using the section navigation keys in the usual way.
