Groups and constraints


Is there a way to apply a constraint to an element in a group and have the group
follow the constrained element? Specifically, I want to align a group I have drawn
in a top view with its counterpart in the front view by applying the collinear constraint
to the two right edges. When I try this, I get inconvenient results: either the
edge alone moves in the top view, or the edge in the front view moves instead.

John,
Groups are a way to create a collection of objects. Constraints will still
work on the elements of the group separately. If you want a collection of
objects that cannot be changed outside of the collection, such as a pocket
on the face of a part, create a rigid set. Rigid Set is one of the
constraint commands. A rigid set fixes the geometry in the set so that it
cannot be modified outside of the set. You can then create a colinear
constraint of one of the lines in the set to a line outside the set and all
geometry in the set will move accordingly.

Rick B.

Thanks, Rick. I had never noticed that feature before. It's a little fussy the
way it shuns offsets, dimensions, etc., but once I understood the rules, it worked!
