AutoCAD 3D 2019 pipe network issues

[ugarrison]

I switched to Civil 3D 2019 and have started finding serious issues with pipe networks that I have not seen before.  We have noticed we will create pipe networks and set all the inverts for design.  We will save and close the drawing.  When we re-open the drawing, the pipe inverts are all reset to what appears to be the pipe rule set.  We have tried un-checking the use values from rule set box under pipe properties and are still having the issue.  I started thinking that it has something to do with our data referenced surface.  I re-adjusted a few pipe inverts as a test, synchronized the surface and the inverts I adjusted all reset!  Is there a new setting that I am not aware of?  Has anyone else seen this yet?

It appears that a work around for this issue is to promote your surface, but that is not something I want to continue doing with all of my projects.

We also have just discovered this problem. Reminds me of the early days of C3D when new releases broke more things than they fixed. Hopefully there is a simple fix, but past history would lead me to believe there is not.

This is also happening to me with surfaces that are in the same dwg as the pipe network and not data referenced.

This is a serious problem that Autodesk needs to address! I'm redoing networks multiple times and don't seem to be able to find a fix.

I was able to recreate this with surface and network in same drawing too. Here's a link to another post describing same problem I believe, albeit a different trigger. link  Autodesk seems to be aware of the problem. A potential workaround is to create a "No_Rules" rule so synchronize can't reapply rules. I haven't had a chance to try that myself.

Hello, Ulrich

This is a known issue that we are aware of with the pipe network using the wrong rules. We are working hard to correct the issue; however, we do not have a time frame yet as to when it will be resolved. We've noticed that it appears to be an issue with reference templates, so a workaround that may help is to maintain the correct path to the reference template and refresh the correct link to the reference template.

Another thing you can try is to use the APPLYRULES command, select the most up-slope pipe or structure, and select the last pipe or structure. In some cases, the correct rule is set in the pipe and structure properties, yet it somehow references the wrong rule. Forcing it to use the correct rule with the APPLYRULES command may help. If that doesn't work, you can try deleting the rules, recreating them, and assigning them.

Hi @ugarrison

sounds similar. See my comments in this topic:

Also, report this to your Reseller ASAP and complain it's MAJOR "known problem". 

Good luck.

the problem is simple ... Apply pipe rules should only be "applied" when the user evokes the command or the rules on pipe objects. it's intended to support new pipe design when users want that ... not destroy existing work. 

Autodesk needs to remove the glitch in C3D 2019 which is automatically applying rules to dynamic objects (especially old drawings from over the last several years.)  We need to work in a Civil world where we are able to revise and add on to previous projects/data/infrastructure.  
The fix is simple.

Thank you for the feedback. I understand your concern about the relative difficulty of fixing this issue. You are more than welcome to submit product feedback to our developers here: https://www.autodesk.com/company/contact-us/product-feedback

This is a HUGE and problem! Every single drawing I open in 2019 that has a pipe network is having this problem. Even when everything is within the rule set limits, it still changes it to some random flow lines that do not even follow the rules. I ran a test to see what would happen if I changed the rule set to have a wider range of limits. See the attached screen shot.

This is not acceptable and is causing our company hours and hours of time to fix this. Can I send you a bill for my time?

Try deleting all rule sets... seems to have worked for me... getting tired of civil 3d being weak

Similar post and refers to two other similar posts.

In our case, this problem has been linked to Reference Templates.   When the drawing is opened, any reference template with pipe rules will cause the pipes to revert back to original design elevations even though they have been edited or tweaked.    (Issue been around since 2017, and as far as i know still has not been fixed... please let me know if im incorrect on this.)   Simple fix for us was to create a set of pipe rules which has "No Rules" in it.  Set that as the default in the template, then have a set of real pipe rules in a reference template for use at the first design of the pipe network simply to keep the pipes from all being at zero elevation.   But you MUST remember to remove that reference template (or at least uncheck it after the initial design, or the problem will keep happening.

Hope this helps.

Any update on this?   I can only find the download for 2020 C3DPipeNetworkRules.dll in the knowledge base, but not 2019.

It's apparent based on the event viewer that the macro can not be run when applying rules.

See attached image...

If this is as i believe it to be, a problem with the reference templates.  Then the issue has (according to Autodesk) been resolved in 2018.3 update.   I cannot speak to 2019 or 2020 unfortunately, but i do know that the problem also existed in 2019.

Hope this helps.

We stopped having the issue when we installed the 2019 service pack 2.  We are now running 2020 and haven't had any issues with it yet.

[CADvisers]

A reference template is not being used in this case.

[john]

I kept 2018 installed and finished out the projects that I'd started in 2018. I started all new projects in 2019 and didn't have any problems with those. 

That being said, I installed 2020 pretty quick and have been using it exclusively. I haven't seen any issues yet.

We have separate base files for sanitary and storm.  When we create a network reference for the storm in the sanitary base file, it is on a design layer no plot.  When we make changes to the pipes and structures in the storm base file, the sanitary base file changes the style and layer to sanitary layers and styles......is there a setting that we need to use.  We are currently C3D 2019.3 update.  This is a real problem.  Has anyone else experienced this?
