3d line

[wfrst2008]

I want to draw a 3d line to join two points with different XYZ values and then
use this line to construct a sweep in place family.
However, Revit doesn't allow me to snap the points (actually they are small circle
constucted in acad and then import to Revit)
How can I do that ? Any ideas ?

You need to place a ref plane an draw on it
