This window lets you modify the IJK range of a structured Part.
Enter new IJK ranges for the Part in the fields provided.
If you cut a range, the corresponding elements are deleted from the Part.
If you extend a range, new (unused) elements are added to the Part.
Use zero or negative indices to add I, J or K lines to the lower end of ranges.
For example, changing the I-range above to run From I = -4 To I = 12, will add 5 I-lines at the lower end of the Part and 3 I-lines at the upper end of the Part. The new I-range will then run from 1 to 17 (with the original I-lines moved to I=5 through I=14)
