Line Art Modifier
The Line Art Modifier allows you to add 2D lines to 3D objects
Just remember that this modifier works only from the view of the camera so make sure your camera is set up before using the modifier
I add a new Grease Pencil Stroke object
I can move the stroke out of view but still selected
Under the Modifiers tab, I add the Line Art modifier
I will use the Source Type of Collection – this makes my collection the geometry source for the modifier
I then select my Collection
For Layer, I choose Color – this is the layer I want to use
For material, I will choose a line color (in this case, blue)
I can also change the Thickness and Opacity
