DWG export - lineweight missing

When exporting to CAD drawing (maptoacad, editable, with template) some polylines got the default lineweight of "0" although the Map display model assigns certain lineweights to them. In Map these lines displayed correctly. For the polylines affected the lineweight was set using an expression:

<Override>
 <SymbolName>LTYP20</SymbolName>
 <ParameterIdentifier>LINEWEIGHT</ParameterIdentifier>
 <ParameterValue>0.35 * 500</ParameterValue>
</Override>

To get the lineweight exported correctly one has to put the expression in brackets:

<Override>
 <SymbolName>LTYP20</SymbolName>
 <ParameterIdentifier>LINEWEIGHT</ParameterIdentifier>
 <ParameterValue>(0.35 * 500)</ParameterValue>
</Override>

DWG-Export - hatch pattern missing

We used some hatch patterns in our display model which we loaded via StyleEditor from external files (xml, pat). We also made sure that corresponding AutoCAD hatches with the same name were available when conducting DWG export - but theses were always missing in the drawing file.

It turned out that the following tag in the layer is responsible:

<ExtendedData1>
 <FileName>S:\GIS\...\Vorlagen\HTypWAV_Wald2.xml</FileName>
</ExtendedData1>

It automatically gets created when you load a hatch from an external file. After removing the tag DWG export worked as expected. Same happens by the way with lines styles.
