AutoCAD DWG - Preserve pattern style of hatches

Hello everyone,

I have a question with regard to preserving the pattern style of hatches in DWG files. 

I have a simple DWG file with two lines (blue), one text (yellow), a dimension (magenta), and a polygon (blue) which is filled with a hatch (cyan): 

If I now simply read the DWG file with a REALDWG reader and do nothing but write it again with the REALDWG writer, 

the hatching pattern looks very different in the result - which is basically because the lines of the hatching pattern are much closer together than they were in the original DWG file:

More details below.

Does anyone know how I need to parameterize reader and/or writer such that the pattern style of the hatch is preserved 1:1? 

In the REALDWG reader, I already linked the read-in DWG file as a "Template File". This helped to preserve the styling of the dimension but unfortunately not with regard to the pattern style of the hatch.

Here some more details:

Regarding the parameterization of the REALDWG reader, I only unchecked the "Explode Dimensions" option, everything else if FME Default.

All the features are read as a single, merged feature type. For this feature type, I exposed the Format Attributes "autocad_layer" and "fme_feature_type":

For the REALDWG writer, I did the following:

• set "Attribute Output" to "Extended Entity Data"
• set the DWG file which is read by the reader as "Template File"

In the feature type writer, the "autocad_layer" attribute is used for the "Layer Name":

The various objects are on different layers in the attached/read-in DWG file:

• 01_Linien: The two lines and the polygon.
• 02_Schraffur: The hatch located within the polygon.
• 03_Text: The text.
• 04_Maßlinie: The dimension.
