Enable Slice to show a slice of the object. Enter the slice angles into the From and To boxes.
Enter a start angle.
Enter an end angle.
The Regular Grid option is only available when Slice is enabled. By enabling this option and entering a value into the Width box you can control the subdivisions within the plane of section of the sliced object. Small values produce a fine subdivision while larger values result in a coarse structure. This subdividing only affects the face (the plane of section) of the slice.
Use this option only if you intend to process the object further after slicing it.
Use the width setting to define the degree of subdivision. This can be used, for example, when an object or only the cut surfaces will be subsequently edited (e.g., bent).
