I have created relative view of solid body from part file. when I modify dimensions in parts it moves relative solid body view from allocated position even though that view is locked.

I work mostly in structure (weldments) so I need to create gussets and ribs. This solid bodies need to be placed in drawing sheet as single part. I lock view of those single body, but when I change dimensions of weldments all solid body views moves randomly in space. Why is this happening and what is solution ?

(To overcome this I always covert those view into sketches.)

first image is after changing dimensions.
