Drainage Labels on Highways Longsection taking values from left to right rather than pipe properties

[Andrew.Carter2EE32]

Afternoon All,

I've drawn a highways longsection and overlaid bands for the drainage pipes.

The USIL takes its level from the "Start Pipe Level" and DSIL from "End Pipe Level" but it seems that when drawing on a longsection these base them the profiles left to right instead of the pipe properties. Does anyone know of a way to fix this?

Hi @Andrew.Carter2EE32 ,

I think that the problem may be in the way you draw the pipes in plan view.

You need to check the band detail to understand where the software is going to get the information.

Try to draw them from the high level to the down level and see if it work's in your case.

Can you attach the drawing?

Regards,

[Andrew.Carter2EE32]

Apologies for the delay. I've attached a copy of a different drawing i'm currently working on. Same problem, pipes seem to take left to right rather than taking it from the pipe start/ pipe end.

Kind Regards,

Andy

Hi @Andrew.Carter2EE32 

The problem seem to be in your band detail.

The band USIL gets the information from the "End Invert Elevation", and the DSIL from the "Start Invert Elevation".

Hope it helps,

Regards.

If you look at Road 3B in plan: Pipe 3.001 is drawn from Start structure Fw11 to Fw10, and pipe 4.000 is drawn from Fw13 to Fw10. Both Pipe properties show the start of the pipe to be higher; and they had to of been drawn this way for me to export correctly to microdrainage.

Looking at the profile view, Pipe 3.001 is taking its USIL from the End Invert Level of the pipe, and the DSIL from the Start Invert Level.

On the other hand, Pipe 4.001 is taking its USIL from Start Invert Level, and the DSIL from End Invert Level.

Due to the fact it swaps; and i'm led to believe that its reading Start Invert Level as the left hand side of the profile view level and not the start Invert Level Pipe property, and End Invert level as the right hand side of the profile view etc.

@Andrew.Carter2EE32 ,

You're right...that's a strange behaviour...

It seems to be taking the direction from left to right as a reference.

Leave that to the experts...

Sorry for not be able to help.

Regards.

[Andrew.Carter2EE32]

No worries, thanks for trying. I'm probably missing something incredibly obvious

[Topmig]

So we are both missing something obvious.
It looks more like a bug..

Try using the "Change Flow Direction" tool in the pipe network modify panel.

I've just tried that, the gradient in the pipe label changes to negative but the Start Invert/ End Invert do not change confirming its coming from profile view rather than pipe properties

Hi all,

Thank you for notifying us about this behavior. 
Indeed there is some inconsistency in Start/End Invert Elevation that is displayed in Profile View Band labels.

It has been noticed that when the pipe is placed in the opposite direction to Profile parent alignment, then the Start/End IL values are swaped. As @Andrew.Carter2EE32 noticed, values are taken from left to right, instead of Pipe Properties.

This has been already reported to Development Team for further investigation under internal ID: 

CIVIL-38826 - Start/End Invert Elevation values swap in Profile Band labels in Civil 3D

Once again, @Andrew.Carter2EE32, thank you for spotting and notifying us about this behavior.  
@KirkWM , @Topmig thank you for your efforts and input into this case.

Regards,
Wojtek
