Projection of The Edges of Families

[endes4455]

How can I see the projections of all the lines of a family on a plan?

I made a family below:

When I draw it on LVL2 I can see all the lines:

But if I draw it under a slab at LVL3, not all the edge lines are projected on the plan:

Actually, I need the bottom edges to be shown. Those are the top edges of the family.

If I switch to wire frame, there is no dashed line.

Is there a way to do this without overriding lines manually?

These are the levels:

Looks like the bottom element is obscured by the top element. So only the top element is dashed. If you want to see both, then create separate families.

Edit the Visibility Settings of bottom part and make visible in "Coarse ".

I did the setting:

But I can't see both lines. Am I missing something?

Are you using the Show Hidden Lines Tool on the Beams?  

This is what you are trying to do; right?

I think I forgot what I was trying to do while trying everything. Yes, that is what I want to do, and I got your point. I will decide what to be shown and set the visibility. This solves my problem. Thank you very much.
