If I select multiple Arcs (e.g. Arc1, Arc2, Arc3 and Arc4) and want them all to have a relation to Arc1, which already has a defined diameter, I simply add all Arcs to 'Selected Entities', select OK and all will be related. However, they are not all individually related to Arc1 (i.e. Arc1 is related to Arc2; Arc2 is related to Arc3; Arc3 is related to Arc4). Is there a way to have all these entities related to a single entity without having to create individual relations for each pair of entities?
