Hello,
Can you think of anyway to add a feature inside a bend rather than its N,M or F points.
More specifically I am looking for modelling a "Double Trunnion" as depicted in following drawing.
Many thanks,

Dear Friends,
I have found the answer to the question last night just by playing with reducer's options.
As we now the reducer has three points on the curve: N (near), M (mid-point) and Far (far). The M by default is located at 50% of the arc, however, it can be moved easily to any other locations. I used 13%. From the bend help:
"Specify whether or not the bend should contain a midpoint along the curvature of the bend centerline. Under default conditions, this option is disabled, and bends are drawn with a TIP, near point, and far point only. Midpoints append an "M" to the end of the point name (i.e., A05 M). This option is useful when placing a support on the elbow itself."
Then from the M-point, an beam element can be added with a pipe profile where you can select the size and material type in non-standard option.
Please see the enclosed photos.
Cheers,
Hello AKO,
Yes, you are on the right path. See WIKI here for full details on this modeling approach:

Hi Mike
This is the one in which the center line of support and pipe coincides with a few mm offset:
However here, here the the center line of I-beam and pipe are apart by Pipe's radius+h/2 of the I-beam.:
Based on your comment, I assume the second model is closer to real case.
Am I right?
Thank you,

yes you are correct that you should take into account the actual dimension of components when locating supports as you have done above.
