Spline Intersection Problem

[nikitesh95]

I am working on The Theme Building, LAX airport. I drew this in Revit Architecture Template by using Extrusion under Structural Framing. i want to Replicate the Arch as it is, and i found Spline tool for that, it helps me to form Solid extrusion. but i want to make some extension over that spline using a different spline, and there comes the problem. two spline are not intersecting each other at a point, TAB key also  not helping with this. Please guide me to draw this, what trick should be used. is it possible to draw that in Revit or need to be imported from AutoCad or something else.

i hereby attach the Snaps of what actually i wan to make and what are the issues

this is spline which makes the Arch, two spline with offset make a solid , and i can do itthe contionous spline is major arch and shorter one is onther which i want to intersect at point on Major Arch, but i am stuck over thisthis is actually the Arch i am trying to make with a major arch and one which take its support to and is part of same Structure

1- Unfortunately, this type of Spline don't intersect except at start and end points. so in your case you can make 3 splines instead of two. whenever you need intersection stop the current Spline and start another.

2- However, there is another Spline tool that don't show except in the Mass families. this one enables intersection at every point used to draw the spline.

I do not mean to discourage you, but which tutorial did you watch that led you down this path in modeling the LAX airport this way?! 

I am asking because it might be better if I watch that tutorial before giving an answer
