Hello, what is the best way to be able to control the place height of roof-based elements in a roof? For example: place a velux M-04 in your roof, and you want the top of the velux is located 2400mm above a certain level. Doesn't work with ref-planes.... Any ideas? Thanks

"Doesn't work with ref-planes...." What do you mean. Refplanes in a project or family. Need more info.

In a project. If you create something as a "roof-based-family", how can you give it some parameter or something, to determine the height to a level once placed in a project...?

I usually build this functionality into the family by creating associations with a "movable" ref plane in a family.

Yes, that was my first thougt. Only the problem is, that in a roof-based family there is no floor, or level...so nothing to align or dimension to?

BUMP.
Can anyone answer this? I am looking to create a height parameter for these, but with roof based families you cannot?
When loaded into the project, some families can't also be moved up and down within elevation. This is a MUST for us to be able to set PV panels and skylights at specifc heights.

The problem obviously is, how does elevation work with a sloping roof? The unit has to move in the x-y as well as z direction.
If yo set a refernce plane in an elevation view, you can probably pick an interscetion of your unit with the roof and slide it up/down the roof to an intersection of the roof and that plane.
