Transforming (Reprojecting) DWG files with Pipe Network features in it, from UTM Zone 17 NAD83 (Original) to MTM 10 NAD83 CSRS

Hi everyone,

I want to transform (reproject) DWG files with Pipe Network features from UTM Zone 17 NAD83 (Original) to MTM 10 NAD83 CSRS. 

I used the following link method.

https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/transform-reprojec... 

When I define query, it prompts that  some entities can't be queried. 

And results contain projected polylines without Pipe networks.

source dwg

projected dwg

Is there any solution to project Pipe network features to other coordinate?

Hi @gis_analyst2022,
Welcome to the Autodesk Forums.
The Attach/Query method of your link only works on dumb linework. To transform Civil 3D Objects, you'll need to use the >>>Coordinate System Transformation Tool<<<.

Hi @Pointdump 

Thanks for your answer and help.

I used the coordinate transformation tool, but unfortunately, it skips lots of features.

and the result is not projected correctly (based on Bing map)

I test this tool for another dwg, and it works well.

@gis_analyst2022,
Interesting. Since it picked up your Pipes and Structures, I wonder what a "Geo Entity" is.
I didn't get as far as you did. I tried twice to transform your drawing and got "fatal error".
