Projections to the floor below

[robmorfin]

Does anybody know how to show a skylight projection when inserting a skylight in the floor below, and also I usually show the boundary of the floor above (not all the walls) as a projection, any ideas?

by the way, I'm using the skylight family from the Imperial Library in the Windows folder.

The easiest way is to temporarily set the view range to show the skylight / foor above and use the linework tool to chage the lines to "above" or "hidden" etc, then reset the view range.

I have tried adding an invisible line to a skylight and also projecting its outline onto the lower level plan, but that doesn't work properly for a pitched roof, since the projection is perpendicular to the roof plane, not the floor plane.

thanks, beegee, i underlayed the skylight level in my view and created the projection with hidden lines; By the way, I locked the projected lines (drawn) to the skylight above, and now every time I move the skylight, the projection goes along.

Yes, thats the way it works. Same with roof plans. If you amend the roof by sketching, you lose the linework association though.
