I am in sketcher with some dimensioned entities. I want to be able to drag certain entities but when I try SW is telling me, "item is fixed, cannot drag". Or vice versa. Also there are 2 centerlines I put in for construction purposes that cross eachother at the origin. I made a relation for each that they are coincident to the origin and I cannot even change the angle of them in relation to the default planes. Is there some sort of automatic relation going on maybe?
