I have a block. I am editing another block to have particular relationships to points on the existing block. When in any sketch command I am unable to pick relevent points of the existing block. SWX2013 sp1.0
"I am unable to pick relevent points"
That is probably the way it is. I suggest you find another way of getting where you want to go.
Perhaps you could create some reference geometry to which each block could be related.
