Excuse me! Yes,you guess that ,which my asking is size as same as daz model when importing model from blender to daz. I use 1 unit=1m in blender,but in daz 1m is smaller than model imported from blender. For example, I created a cube (1m) in blender,then importing into daz,and I use unit 1m to created cube in daz,which I found that daz model is smaller. So I want to know how to let size as same both in daz? Thanks.

There's a blender preset when importing. If you export an object from Daz to blender (e.g. Genesis 8 Male) using the Blender preset - then import it to Blender, you can use that to make your object the right size in Blender. Then you import your object to Daz with the same Blender preset.

Hope that helps

The Blender cube was probably 2 meters because when enter the size in Blender it is for the radius of the cube.

Thanks guys.
