Pass

Pass allows automated passing of nominal sizes from an initial component or stock to adjacent elements, and so on, when certain conditions are met.

Nominal size detection

Whenever a component is placed, its nominal size(s) are detected according to the following scheme (<c> and <ns> correspond to the contact/nominal-size prefixes you assign as user preferences — e.g. C1→DN1, C2→DN2):

• A port named <c>i (i = 1, 2, 3, ...) has its nominal size in an attribute named <ns>i.
• If a port named <c>i (i = 2, 3, ...) does not have an attribute named <ns>i, it uses the attribute named <ns>1.
• If the port has no attribute named <ns>1 at all, it has no nominal size.

Whenever a stock is assigned, its nominal size (and that of its two ports) is always detected from the stock attribute <ns>1.

At each port of the placed component or assigned stock, a connecting port from another component or stock is searched for and its nominal size is detected as described above.

Inconsistencies

An error message is displayed for any inconsistencies at a connecting port, and passing through ends at that point. An inconsistency occurs when:

• The connecting port has a different nominal size than the one to pass through.
• The connecting port belongs to a universal component and is a non-stop port, and the nominal size to pass through differs from the nominal size of at least one other non-stop port of the universal component.

Assignment rules

The connecting port is assigned the nominal size to pass through if:

• It does not have any inconsistencies and it belongs to a universal component.
• It is a non-stop part — in this case, the nominal size to pass through is also assigned to all other non-stop ports of the universal component.

Stop conditions

Passing through of the nominal size stops at a connecting port if:

• The stock that owns the connecting port is a stop stock.
• The component that owns the connecting port is a stop component.
• The component that owns the connecting port is a universal component and:
  • The connecting port is a stop port, or
  • It owns stop ports only, or
  • All its ports have nominal size inconsistencies.
• The component or stock that owns the connecting port has a different RUN_ID than the one by which it was reached.

Routing Logical allows you to start passing nominal sizes from an existing component or stock. Once a component or stock is selected, its nominal sizes are displayed; before starting the actual passing, you can change any of the nominal sizes and the new value(s) will be used.
