Count based on other measure count

Hi Avian65 ，

You can create a measure as below to get it, please find the details in the attachment.

Count of items where Drawing measure is 0 = 
CALCULATE (
    DISTINCTCOUNT ( 'Merge1'[Id] ),
    FILTER ( 'Merge1', ISBLANK ( [Drawings] ) )
)

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
