Creating a dimension with MMB

Hi there,

I need help. I've received a ASME drawing in inches from a client (i usually work on ISO and with mm) and they've demanded that I measure a position with the MMC condition in the hole and for each datums (B and C).
The thing is that i don't know what values i have to put in the datum MMC size and why the third datum (C) appears like a plane in the repport when actually is a hole?

What i need to know is what values do i have to put in the datum MMC size and why the third datum have to be a plane for pc-dmis?

Attached is

the dimension requirement.

Thanks in advance.

Just one last question. It's normal that the feature appearence of Datum C to be the one bellow (like it was a flat feature)?

{"data-align":"none","data-size":"large","data-attachmentid":485752}

No. Are you sure CYL_C is truly a cylinder? Can you post the code from Cyl_C.

Note: When naming dimensions, only use numbers, letters, and/or underscores. Spaces, hyphens, and special characters typically don't work well for PC-DMIS.

The code is here:

CYL_C =FEAT/CONTACT/CYLINDER/DEFAULT,CARTESIAN,IN,LEAST_SQR
THEO/<2.4034,0,0>,<0,0,1>,0.283,0.3
ACTL/<2.4034,0,0>,<0,0,1>,0.283,0.3
TARG/<2.4034,0,0>,<0,0,1>
