parabolic arch

[Anonymous]

I'm a 1st year on architect. Could anyone pls tell me how to create a parabolic arch using Archicad? I'll be very grateful!

The complex profile tool turns a fill into a wall.

Make the fill look like the parabola

Draw the wall perpendicular to the arch direction.

and taper the arch with a solid element operation
