When a .dwg file that is associated with a model is opened in AutoCAD, without the Bentley Hydraulics and Hydrology product integrated, the elements appear as boundary boxes.
When the .dwg is opened in AutoCAD with the Bentley Hydraulics and Hydrology product integrated the elements appear normal.
This may be due to proxy graphics settings.
1. Open AutoCAD with the Bentley Haestad product integrated
2. Enter the command: SYSVDLG
3. Set the following System Variables
PROXYSHOW = 1
PROXYGRAPHICS = 1
4. Click OK
The elements should appear correctly in AutoCAD with or without the Bentley Haestad product integrated.
