Assembly constraint

[descatia]

when I use the coincident constraint i get an error like this

""""""This function works with the active component 9blue product) It positions child products relatively to other child products.""""


How do I make one of my components active, and assemble by components.

Be sure you're at the top level. To do that, double-click on the top level assembly in the Sec. Tree. To make a component active, let's say you have a Product called "Assy", and three parts under it, "A", "B", and "C". To activate part "A", hit the plus sign beside the "A" and double-click on the next "A". You'll see the icons change from Product level to Part level features. To get back to the top level, simply double-click on the top level "Assy" in the tree.
