What length in pixels does a Wings3D unit of measurement equate to?

my hole that was made using 15 of the scale prints as a 30mm hole instead of 15.

Hi frostic. I think you didn't realize that you want the hole to have 15 units of DIAMETER instead of RADIUS.

To get it the way you want, you need to create a cylinder using a value of 7.5 units (half of the diameter.)

oh so the setting is radius not diameter. Good to know as I'm using wings3d to design robots. cad is ok but I prefer wings ease of use. have been using wings for many years. just never used it for 3d printed parts. Thank you

Cool.
Maybe you could share with us some screenshot of the project and a picture of it ready (assembled).
