Moi and Blender (Grouping to render question)

Both methods work.

Question what is the difference between naming object and assign colors.

The reason I ask because I tried importing a drawing with different parts into sheetcam and I expected it since they were named differently for
each part to get its layer.

Only when I assigned them different colors it imported with different layers.

Thank you!
