How to scale up OBJ file to correct scale

I have OBJ files of humans but when open them they are only about 70mm height

See attached example

Possible to scale up to correct 1:1?

I don't think this is possible in Inventor.

Hi! Mesh file is generally unitless. You can "scale" it by importing to different template. In this case, the logical template is inch. You will want to start an inch-based template or select "inch" as the import unit on Import Options dialog.

Many thanks!

When importing, click the obj file, then click options. You'll be able to pick specific units.

Thanks! I miss an inch template ...We only work metric. Do you have one I can test with?
