Problem with Creating Alignment and Profile from Corridor in Multiple Regions

[khaledCULN8]

Hi,

I have multiple region Corridor.

whenever i try to create an alignment and profile from corridor to a certain feature line that extend to multiple regions,

all the infromation i get from the profile are wrong (does not match the corridor surface at all)

I tried a different feature line that only extend into one region, and it worked perfectley.

has any one experienced this kind of problem before?

Hi @khaledCULN8 ,

Could you provide more details regarding your issue, please?

• What Civil 3D version do you use?
• Do you use custom subassemblies within your corridor?
• Are you able to export feature lines from the corridor correctly?
• Could you record a short screencast video that will reflect your problem?

Is it possible to share your file with us? It could be very helpful to find the best solution for you.

Looking forward to hearing from you.

Thanks,

Is all of the profile wrong? Or certain parts? By how much?

Hi @garwo ,

I'm using Civil 3D 2020 with the latest update.

I'm using Custom Vertical wall that i created with subassembly composer. 

i thought that this might be the problem, that's why I replaced it with the vertical wall from the civil 3d Library.

and i got the same result.

when i create the profile directley using profile from corridor, I got right results.

please see all the above in the screencast I attached.

also, I attached the file below

thank you in advance,

khaled

Hi @khaledCULN8 ,

Thank you for the screencast and files. 
I'm currently investigating your file and noticed that there are multiplied Wall subassembly attached to the same point of assembly. In the worst-case scenario, I've count 4 of them. Please see:
 
Is it as intended? Please explain.  

Also, I cannot rebuild correctly your corridor as I'm missing a few more subassemblies:

• Custom_Lane_V0
• Daylight_V0
• EG_Cross_Section_V0
• Steel_Barrier
• Steel_Barrier_V1

Above are essential to recreate correctly your corridor and to provide you the best solution.

For now, as a workaround, I recommend you to create a profile based on existing ground. RW_Hinge point code is generating on the crosscut of the existing ground and a vertical wall, so it should show elevation on the profile correctly. 

Looking forward to hearing from you.

Hi @Wojtek_Garczewski 

True, I've multiple Vertical walls at the same point.

Each wall comes with its condition. you can delete each one except RW 636.

as for the remain of my custom subassemblies. there are attached below.

here is the path where i saved them in my PC

Hi @khaledCULN8 ,

Thank you for providing all the details. I've looked into your file and tried different settings (e.g. changing frequency of the corridor) - no luck. 

It looks because of very complex geometry and quite developed assemblies(targets, conditions) which are changing their layout accordingly to the conditioning targets, Civil 3D encounters problem to export alignment with the associated profile correctly. It is hard to find one direct location that causes the problem as the model is in quite advance stage. 

In this situation, I recommend you to Create Alignment from the Corridor and create a profile from Surface (existing ground). It should reflect the elevation of the intersection point between the existing surface and vertical wall.

Another solution is to create a feature line from the corridor and display Quick Profile with a 3D entity profile displayed. After that, you can export it to LandXML, delete the origin feature line, and import it back as an alignment and profile. It's a simple trick, but it works perfectly. Please see the screencast that explains this solution step by step: Export feature line to alignment and profile

I hope that the above will help you to move forward with your project works. If you need any additional assistance please respond and I will be happy to help.

Regards,
Wojtek

Hi @Wojtek_Garczewski 

thanks for the quick response.

like you suggested before, I’ve created an Alignment and a profile from the EG.

thanks for the help
