Associate Profile Parameters with Sweep

Someone says, nesting family is not a very good option. But I disagree with it.
Nesting family can make families more convenient and easy to create, control and modify. It saves my time.

Once, I've tried to make a sweep family.  It had parameters which can control the parameters of nested profile family. I gave some instance parameters at the profile family as usual, and tried to connect them to the parameters of the sweep family. But the parameter window didn't show enough information of the nested profile family. it was unusual.

Where are my Parameters????

Manipulating Nested Family

Lintels are necessary when doors or windows are on a masonry wall.

Then, how can they placed in Revit?

1. Make another door family which has nested lintel family.

It's easy but two families for one same door because of only lintel? And how can make lintel schedule and tags for lintel? And if a wall type changes?

2. Place separated lintel family in a project. then easy to make lintel schedule.

But, finding, placing, aligning....it's so annoying.

Here is the way I use.
