Naming Solid

Hi everyone

I’m using Civil3d 2020

I have Subassemblies named Lane1 Lane2 and Lane3
After creating the Corridor and Extracting the solids, I want to name each of the solid based on their Chainage and Lane.

1st problem:
Whenever I finish writing the Dynamo file, certain nodes keep disappearing. (Objects Type and All Objects of Type)

2nd Problem:
I can’t seem to make it so that Chainage 0, comes back as CH 0.00. It keeps showing CH0

If anyone see my set of work here being not efficient, do highlight it as I would like to improve as well

Thanks

Property 2.dyn (932.3 KB)

I tried placing a Python Node and it goes missing as well after saving the DYN file.
Any idea why this happens?

Issue resolved.
