Source / Destination Arrow Issues

[Anonymous]

Having an issue with Source & Destination Arrows. 

This happens when using a Source arrow and Destination Arrow on the same sheet or from one sheet to another. 

• Draw a wire. 
• Assign a wire number
• Add a Source Arrow (I've named it the same as the wire number and I've also named it something completely different from the wire number).
• Draw another wire. 
• Attach the Destination Arrow
  • When selecting Project to see all Destination Arrows, I can see my source Arrow. 
• When I click Freshen, that source arrow (along with any other source arrows), disappears completely. 

I can manually type in the Signal Code and everything references as should. 

Is there a way of correcting this?

Is the drawing part of the active project?
Is this a custom signal arrow?
Can you share the drawing, so we can have a look?

Thanks for the reply. 

Yeah, its the active project. 

The signal arrow, is style 1 with the attributes slightly re-positioned, but I've had the same issue with style 2 which is unedited. 

Here's an additional head scratcher; after adding a destination arrow and getting the blank Project Wide pop up, I then insert the arrow with either a source code manually typed in or a random code just to add it to the drawing.

I then edit that destination arrow, click the Project button and I get all the Source codes. I'm able to click Freshen and it actually freshens the list instead of removing it.

Your screenshots says that these are stand-alone signals, not source/destination signals...
Can you supply me with a DWG-file?

Strange. Ok, DWG attached. Thanks for taking the time.

Your signal symbol is missing the WIRENO attribute.
What happens if you add this attribute to the symbol, and update all the existing signal symbols?

I think you've sussed it.

When I edited the block, I assumed the wire number would be linked via the cross reference and the WIRENO attribute was there purely as description. 

Key word in these, 'assume', mother of all ****ups. 

In the process of updating my blocks and will report back.
