Description:
The “Units” refer to units of measurement. On the Tool menu select General
Options and click on the Environment tab. Here you can select the program’s
language and the default units (Metric or Imperial).
Some settings in the program(such as density) are in embroidery points (pt).
One (pt) is one tenth of a millimeter, which in general is the resolution of the
embroidery machine.
