Hello everyone. I am now tring to build an airway geometry of human's lung. But there are something wrong with it. I have post it in the following address. Please help me to have a look at it. http://202.113.227.137/private/adang/airway/flange.html Thank you very much.

Hi Adang,

It looks like you have created the surface just fine. You still have to close off the ends, however, in order to generate a B-Rep solid. To do so, combine the curves at each end into a single closed loop using Create>Curve>Chain. You can then create planar trimmed surfaces using each loop as the "outer loop" in the Create>Surface>Trimmed form.

Regards, Robin
