General Remarks

Parallel cut planes can be used with both Basic and Deformed space, and may have contours displayed on them. However you should note the following:

Generating the graphics for multiple planes can become quite slow if many cuts are made through a large model. This simply because it requires a lot of maths to calculate all those slices, so don't be surprised if processing these sections is slow.
Once computed the rendering of multiple "thin" planes should be reasonably fast, however multiple "thick" sections may be quite slow to render since the hardware is having to do a lot of clipping calculations each time the display is updated.
Screen-picking from multiple sections is also difficult since, in theory, an element could be cut many times giving many potential candidate locations for selection. Therefore screen-picking is only approximate when multiple sections are in use, and while it should find "cut" elements it may occasionally also select elements that are not visually correct. If this happens try moving the selection point a little.
