Aras karimi

The distance between the two surfaces is 0.2 meters, the front surface is located at the origin of the coordinates and the back surface is located at -0.2 meters from the origin of the coordinates, in other words, the back surface is located inĀ  -Z.

Now, there are three zeros in the offset section. Does that mean three values should be written here?

What numbers should I write?

please help me

Thank you
