Flat Oval Mitered Elbow With Turning Vanes

[jmongelli]

Hi, does anyone have a family for a flat oval mitered elbow with turning vanes? I've searched high and low and cannot find one. If not, does anyone know how to make turning vanes appear on the stock flat oval mitered elbow family?

Thank you.

I would say, start to learn to make/edit families. It will save you time in the long run. When you know how to create families it wll save you the time to search for every component and can make them to behave as needed. It also will give a more consistent look to your models/drawings when the families are coordinated.

In the US (metric) library there are square elbows with vanes. You could study how they have been made and see if you can do something similar to your oval elbows.

I've never seen that type of family,  you'll probably have to make it.

I've also never seen an oval elbow in the field with vanes.  Does SMACNA or ASHRAE give guidelines for vane spacing in oval elbows?  Rectangular radius elbows have an odd vane spacing factor based on the "curve ratio" given by SMACNA.
