CAD file related to the as-built drawings t

There a many types of CAD-files depending on your use case. If you’re just starting, I would recommend this article:
Working with CAD Data and FME – FME Support Center
Most of the tutorials have example data attached like this one

Hope this helps!

Thanks, ​@max_h , for your response. I am currently working through these tutorials to build my understanding. If you or anyone else in this community have any sample CAD files for water and wastewater as-built drawings, I would greatly appreciate having a look at them as well.

Hi ​@purvipancholy,

I did a quick search for publicly accessible municipal files, and you could try using some of the open source municipal data that is available online:

City of Langley, BC (open data license, free for any use including commercial, with attribution):

• Water Utility (DWG) — mains, hydrants, valves, pressure zones, reservoirs, service lines
• Sanitary Utility (DWG) — mains, manholes, inverts, lift stations, service lines

City of New Westminster, BC (open data license, free use with attribution):

• Water Network Asset Bundle (AutoCAD) — water network assets in AutoCAD format
• Sewer Network Asset Bundle (AutoCAD) — sewer network assets in AutoCAD format

A few more FME tutorials worth working through once you have the data:

• AutoCAD DWG - Which format should I use? — background on DWG vs. other CAD formats
• AutoCAD DWG Block Attribute Extraction — hydrants/valves/manholes in these utility files are typically blocks with attribute tags, and this shows how to pull those out (includes its own sample DWG for practice)
• Working with AutoCAD Layouts — useful once you’re ready to look at paper space/viewports rather than just model space geometry

Hope this helps! 

Thanks ​@veronikaatsafe … I will look through this CAD files

Hi ​@veronikaatsafe and ​@max_h, 

Thank you for providing publicly accessible municipal files and the basic FME tutorials for CAD files. I am now exploring how FME can be used to perform the following checks on CAD files before they are loaded into ArcGIS:

1. Check whether all mandatory attributes have been entered and identify any missing attributes.
2. Link CAD files with the Excel template using a unique ID, allowing attributes from both files to be combined and validated.
3. Verify that assets in the as-built CAD drawings have the correct connectivity. For example:
   Water lateral pipes are correctly connected to water main pipes.
   Water meters are correctly connected to manifolds.
   Other network assets are connected as intended.
4. Check whether the received CAD files meet the required data and drafting standards.

Is there an example FME workflow available that demonstrates how to perform any of the checks listed above?

Any guidance, sample workspaces, or references from this group would be greatly appreciated.

Thanks in advance.

Hi...anyone from this group can support this?

Hi ​@purvipancholy,

For validating your data, we have a series of articles depending on your needs: 

• Tutorial: Data Validation and QA with FME
• Validate your Data's Attributes with the AttributeValidator Transformer

For validating geometry specifically, you can use the GeometryValidator transformer as well.

I also recommend signing up for the upcoming webinar (November 12, 2026) on Data Integrations for AEC Professionals:

• FME 101: A Beginner’s Guide to Data Integration for AEC Professionals

Thanks ​@veronikaatsafe for sending this tutorial and information about the webinar. Is this webinar free to attend?
