Hi Fred,

I would have two questions regarding your WB.

1) What is the intent of the property "Rib Profil" which i circled in the attached Picture?
I can change the profile by typing in a new number in the section "Naca Profil".
Is Rib Profil only necessary if I want to use a DAT file?

question ribprofile.JPG

2) Is it possible to select and/or attach the rib geometry to a vertex?
When I create a rib it just appears at a random point and I didn't find a way to set the origin during creation.
It would be helpful if I could fix the leading edge of the rib to a parametric vertex.

BR,
Will

We need to know how actual airplanes are built to understand features we need in this WB. What are ribs made of? Sheet metal? So we need function to convert ribs to press forms to make sheet metal ribs. I mean who cares about toy planes when actual planes cost about $3k per kilo? I don't think aluminum is so expensive :lol:
