Have successfully added WMS data without any problems - it's a bit slow though - but canot get the WFS connection to get any layers.
FYI we have free access to our data in Denmark. We just need to make an account and within that make a service user for our login.
The message within AutoCAD Map 3D is as following:
There was a problem accessing the connection's schema information.
The HTTP request could not be understood by the server due to malformed syntax.
An example - at this site:
https://datafordeler.dk/dataoversigt/matriklen2-mat2/matriklen2-gaeldende-og-foreloebig-wfs/
I've tried to get the database layers both via the URL and the GetCapability, where I change the xxx with my service username and the yyy with my service password. Works great for WMS services but not for WFS services.
I have no issues in QGIS, where I tested URL's for both WMS and WFS services just to make sure they worked.
Hope someone can help me with this.
