Hi there,

 

Can someone please advise what the red lines are appearing on my drawing? See attached screenshot.

 

Thanks in advance.

It seems only the project file is attached, dwg files (x3) are still missing.

Can you expand a little bit on what is going on? I can see the break on the wire in the third sheet, but I can't reproduce its creation. For me, your signal arrows behave as expected. I can't actually find anything wrong with them, it all looks good here.

I changed the number of the wire at the source, then did a project wide update/retag. Everything updated as it should, except that it stopped at the wire break on the third sheet. Doing the same thing, but repairing that wire break first, resulted in getting the wire number update all the way through to the final destination.

Was there originally a wire number where that break is? I noticed you're using in-line wire numbers. Are you certain that the break didn't exist before updating your signals? There's nothing about the signal commands that should affect an existing wire, other than to change its number or layer. (Landing a destination signal sometimes prompts you whether or not to update the destination wire's layer to match that of the source wire.) But those two things are it - no other ways (should) exist for the signal commands to affect wires.

When you land a destination signal, it should place a wire number on the wire for you. It looks to me like this happened, but the number was later deleted. Then, when you went back and updated the source, it placed a new wire number for you on sheet 3 - but since the original number was deleted somehow, you were left with a wire break.

When updating signals, you usually don't have to mess with the existing wire numbers at all - they should all update and remain in their current locations. One issue is with inline wire numbers - if the new wire number is longer or shorter than the old one by too much of an amount, the gap between the number and the wire can be too big, or even be so small that the number partially is over the wires. But, nothing about signals should create breaks in wires.

Hi Arlene.

Have you tried to run a DWG audit on your project?

 

There are LOTS of errors in your drawings, and some of these might cause you problems.

Hi Jim,

 

The break did not appear until I tried to update the wire no. at the source.

 

Thanks & regards

I wonder how that happened; I tried a few times yesterday and then again this morning, and I can't replicate it. Your sources and destinations work normally for me. After deleting the destination on sheet three, and repairing that break in the wire, if I insert a new destination on that wire, it places an inline wire number right where that break used to be. That's what made me think that somehow a wire number was inadvertently erased.

I don't know if the errors that appear in an electrical audit are affecting this, but cleaning them up wouldn't hurt.

Are you able to reproduce this wire-break thing on your end or did it just happen the one time?

Thanks for keeping up with the feedback and input as we try to figure this out. I know it's frustrating sometimes, but we'll do our best to get you together.

Hi guy's,

 

I've finally got it working. What I did was I removed all wire numbers in the supply lines then ran the dwg audit then inserted source and destination arrows which inserted the wire numbers from the power dist source sh1 then I updated the wire number at the source and finally ran the AEUPDATESIGREF command. Do you always need to run this command or can you set your project up to do live updates when you change a wire number? Also when do I use a fixed wire number? Do fixed wire numbers always appear white instead of green? Where can I find the setting to adjust the size of the wire number text and source and dest arrows and text before insertion.

 

Thank you so much for your time and effort guy's it's very much appreciated.

I normally manually  AEUPDATESIGREF to make sure all signal and wire numbers and grid references are upto date.  One thing this command doesnt do is: is if you update the DESC field of the source arrow, it wouldnt automatically update the DESC field of the destination arrow. You have to repick the source code again to update the destination arrow DESC filed. 

 

Ref fixed wire colours - it depends on how you set it up. I normally set RED for Fixed wire numbers / Tag numbers etc and Green for child tag and other wire numbers (not fixed). Colours can be changed in the layer properties, see attached.

I do the live update thing. AEPROJECTPROPS>Cross-References>Real-Time Signal and Cross Referencing. I never have to use the command AEUPDATESIGREF. I tend to use AEREBUILDDB a lot, and anytime I have to make changes to sources/destinations, I rebuild the database before and after. I'm not sure that it does anything super special, but it keeps the xdata associated to the signals cleaned up and that's why I do it.

Be aware that if you turn on real-time signal and cross-referencing, that certain commands will then do things you haven't seen them do before. Anything you do that forces a change to something on another drawing - like changing a source's wire number, or swapping a contact from NO to NC, will make ACADE immediately update the linked component, whether it's a wire tied to a source, or a child tied to a parent, etc. Sometimes it will temporarily open a new drawing to do this. Just let it do its thing. Trying to input commands while it does this can cause ACADE to hang up because it's still paying attention to the command line while it's running the script that controls the real-time updating. But, this is preferable to me than trying to remember on my own to pay attention to the task list and executing it.

As for fixed wire numbers, if you need to use them on a wire that has sources/destinations, I would always place the original fixed wire number near the source arrow. From there, use the Wire Number Copy command to show the wire number at its destination(s).

The color for the fixed wire number is dependent on the settings you have applied to the layer WIREFIXED. When you make a wire number fixed, ACADE switches it from its original layer to this one. So, if the color of a fixed wire number isn't to your liking, you can change it in the layer settings and each fixed wire number will be that color. Personally, I like the color change because it allows me to know without having to click on a component, whether or not it's got a fixed tag, and same for wires.

If you want to change the size or position of the attributes in the sources and destinations, you'll have to make edits to their blocks. Remember that if you do this, you'll need to either A) use the Swap/Update Block command on the existing symbols, or B) delete the symbols, use PURGE to remove them from the drawing database, and then re-insert. I've never used Swap/Update on a signal arrow, so I can't tell you how well those symbols behave with that command.

Ramesh.kambang makes a good point. When you change the description at the source, you have altered its unique identity, and the destination will eventually lose its connection to that source. Updating won't fix it, because ACADE will try to match the description that exists in the destination with a source carrying the same description. You will have to re-establish this link via the Edit Component command, and select the source from the project list.

Thank-you for the advice Jim.

 

What are the advantages of using a fixed wire number?

Your  test project wasn't attached...

In the meantime try doing a cleaning of the drawings usign the DWG Audit tool (Reports/schematic/DWG Audit), this will delete the phantom items that may contribute to your problem.

Using a fixed wire number ensures that it won't change if you use any of the automatic wire number commands. If you never try to number wires on a drawing-wide or project-wide basis, there's really not much of an advantage, because you're adding the numbers on a selective basis where ACADE only numbers the wires you pick. So, in theory, they also only change when you tell them to.

Sometimes Fixed wire numbering feature is really handy:

  • if you want to show the existing wire numbers on a drawing. We dont want them to be renumbered. They will not be updated when you run wire numbering drawing wide or project-wide. 
  • I normally change all wire numbers to FIXED once drawing is fully singed and approved (issue 1). When time comes to up-issue the issue 1 drawing due to the introduction of the additional wires on the drawing, wire numbering will take place only on on the new wires. Hence you keep already approved wire numbers unchanged. We should not be renumbering already approved wire numbers because system or component might have been wired iaw issue 1 drawing. 
  • Same thing applies in FIXED TAGS.

Hi there,

 

I am experiencing the same problems again. Can someone please take a look at these drawings for me. The destination arrows on dwg Test 2 seem to both want to be wire number 2004 where as I have linked them to the correct source on dwg Test 1. One wire should be wire number 2003 +24vdc and the other 2004 0vdc.

 

Thanks & regards

I'm not sure how, but there is a short circuit. I have delete the wires between the 24VDC and R9-R10 and put the wire again and the problem was solved.

I just noticed the short circuit when moving down (SCOOTing) the 0VDC wire.
