Hello Alex,
Below is information from Equipment Help file related to annotations:
The size of the annotation is scaled using the values of the following setvars
DIMTXT – Text size
DIMSCALE – Scale of the dimension features
DIMEXE – Length of the extension line (for the leader)
DIMASZ - Size of the arrow
I hope this will help.
Please let me know if you will need further details.
Regards,
Artiom
