When working with Imperial WorkSpace there is an issue with the dimensions for substructure/superstructure drawings. The generated drawings will show like in the picture below.
This happens because of a wrong text style saved by the platform for the dimension styles OBM_DimUS and OBM_DimSecUS.
This issue can be easily overcome by following these steps:
1. Go to Drawing workflow -> Annotate tab -> Dimensioning group and open the Dimension Styles dialog. Scroll down and select OBM_DimUS (OBM_DimSecUS) dimension style.
2. Change the text style from None to OBM_General_US.
3. Save the text style from the library to the current model. Now you can generate drawings without the issues presented above.
4. If you previously have generated drawings when you save the text style (step 3) OBM will ask you if you want to update all the dimensions that have this text style. Choose "Yes To All" and all of your previously generated drawings will show the correct text style for dimensions.
After step 4, the previously generated drawings will show like this:
