Dessinez une bouteille de Klein
I can attest this will be the most clunky entry in the challenge, but still I wanted to prove Revit is capable of out of the box complex curved geometry. Remember this is not a NURBS modeler.
Create: Revit: Family
--> Generic Model.rfa
Create: Revolve
--> Draw center axis
--> Use arc-lines to create outside shell shape of lower half (non-neck)
--> Use offset tool to create inside shell shape of lower half (non-neck)
Create: Sweep
--> Draw neck shape
--> Edit profile, draw circle that matches all the shapes used in the revolve
Apply: Material: Glass
--> Select the upper and lower modeled parts and apply material
(edit curves/model to desired look/fit)
