Class Information
Number: 52/80.2
Name: Static structures (e.g., buildings) > Compound curve structure > Hyperbolic parabloid shape
Description: Compound curve structure which is in the form of a saddle shaped quadric surface wherein all sections parallel to one coordinate plane are hyperbolas while all the sections parallel to another coordinate plane are parabolas (if proper orientation of the coordinate axes is assumed).
