Accounts with five options of precision in the number 

00.0

0.00

0.000

0.0000

You can customize the number with the help of the conversion Factor 

You can Customize the prefix based on the conversion factor of the number. 

If you have a 1:1 drawing for example of a stair detail and the result you are looking for is: "00.00 CM" then your conversion factor must be 100 and the prefix "CM".

This way you will get "00.00 cm". 

If you leave the reference box checked, your reference base point for the elevation will be y=0 of the model space coordinate system. 

If you do not check the reference box, the plugin will ask you for a reference base point in order to calculate the height with respect to that new point.
