Hi All, i’m having an issue writing to an AutoCAD DWG file, with a template file. I want to preserve the Model Space, but not the Paper space as i’m editing some attributes within the drawing title block in FME which I want to write back out in the paper space.

Even though I am setting preserve paper space in the writer to No, the original blocks from the template file, including the original attribute values, are being written as well as a copy of the block with the new attribute values I have updated in FME. As a result I have 2 overlapping blocks, 1 with the new values I want to keep and 1 with the original values I am trying to replace. I just want a single block with my new values.

In the attached, you can see the output from the writer, with the same block duplicated with the new value I have updated and the old value in the template (highlighted in yellow).

Any thoughts/ideas/assistance with this would be greatly appreciated, whether this is possible or not possible. I have done similar in the past when updating attributes on blocks in the model space and preserving the paper space so I am struggling to understand why I am getting this issue.

 

I have been writing the updated attribute info within the fme_attrib_info().field_value list.

I am using FME version 2023.2.1

Hi tbarker1986,

I have no solution, although I’m experiencing a closely related issue. I’m using the input DWG file as a template file in the RealDWG writer and setting the “Preserve Templete File Model Space Data” as No, but the output file contains both the written data and the data from the source file.
 



I’m using ​​​​​​​FME version 2023.2.2.
