Can someone explain why i can't use the majority of the alignment tools? The only tools that work are one that are "between entities". For example, i want to add the free compound spiral line spiral between two curves but when i select the two consecutive curves in my alignment it says "cannot attach an entity to a free entity". If the "free entities" are just for design drafting purposes similar to LDD, then how do i add them to my alignment after i've created them?
Thanks.
