Setting Z-Values
This section shows how to assign and change element z-values.
The Generate Element options for assigning z-values are:
• Element
• Shared Part
Use the normal Creo Elements/Direct Drafting selection techniques to select the elements to which you want to assign z-values.
If you select a part and you have clicked Element in Generate Element, all elements in that part are assigned the specified z-value. This works recursively down to all subparts.
Additional options for the above command can be selected from Options in Hidden:
• Above
• Below
• Same
• Between
• None
You can set a z-value by clicking Current Z Value in Generate Element and entering a numerical value; this is assigned to each drawing element in your selection.
The Creo Elements/Direct Drafting default is that any existing z-values will be overwritten. If you don't want to overwrite z-values that have already been assigned:
1. Click Element in Generate Element.
2. Select the elements to which you wish to assign z-values.
3. Enter KEEP via the keyboard.
4. Enter a numerical value.
You can also click one of the options Above, Below, Same, or Between. This will result in a computed z-value.

These options only influence elements that already have a z-value assigned to them.

If you select a group of elements for a z-value change that have a range of z-values (lower limit — upper limit) already associated with them, the range relationship will be maintained.
To understand the effect of using the options Above, Below, Same, or Between, refer to the following four examples:
Example 1
Suppose you have a group of elements with computed z-values 1 to 9 and you then specify that they are placed at the same (click Same) z-value as a reference element with a computed z-value of 20.
The result of this operation is that the z-values of all nine elements are computed and set in the range 20 to 28.
Example 2
Suppose you have a group of elements with computed z-values 1 to 9 and you then specify that they are placed above (click Above in Options, Current Offset = 1) a reference element with a computed z-value of 20.
The result of this operation is that the z-values of all nine elements are computed and set in the range 21 to 29.
Example 3
Suppose you have a group of elements with computed z-values 1 to 9 and you then specify that they are placed below (click Below in Options, Current Offset = 1) a reference element with a computed z-value of 20.
The result of this operation is that the z-values of all nine elements are computed and set in the range 11 to 19.
Example 4
Suppose you have a group of elements with computed z-values 1 to 9 and you then specify that they are placed between (click Between in Options, Current Offset = 1) a reference element with a computed z-value of 20 and another reference element with a computed z-value of 40.
The result of this operation is that the z-values of all nine elements are computed and set in the range 21 to 29.
