„

If you created RF obstacles for an area, all objects in the area are 
converted into separate RF obstacles.

„

If you created RF obstacles for multiple selected objects, all objects 
you selected are converted into separate RF obstacles.

„

If you created RF obstacles for grouped objects, each grouped 
object is converted into a single RF obstacle.

draw four lines in a square shape, which are treated as 
four separate RF obstacles.
