Hello
I am trying to import a CAD file in water hammer where below notification was found!
Hello Bushra,
This error is seen in Modelbuilder while importing CAD files, there might be some issue with the CAD file, is the dxf file opening correctly in CAD application?
Please try following troubleshooting steps like exporting the data to DGN and saving as DXF lower format-e.g. 2010 etc.
Error when importing a .DXF file with ModelBuilder "Attempted to read or write protected memory..."
Please let us know if this helps or not.

The DXF file opens normally it is 2018 format
Did you try saving the DXF file into another format? Open the DXF in AutoCAD and go to Save As and change the file type to something like DXF 2010, DXF 2007, and DXF 2004.
If that doesn't help, we will need a copy of the file to look into it.
