I am currently making a bypass part for a ventilation duct in Solidworks. Given the complex geometry of the part, I decided to use surface functions and then build a volume body. To do this, I set up two staggered surfaces (inside and outside). Only I can't sew all the surfaces together because there is an infinitely small space between them. So my question is, how can I fill this space, or how should I go about creating a volume body from my initial surface.
Your tubes are not tangent so airflow problem and possibly nests in.
So bt22's proposal is much better;)
Maybe you need to make your outlets perpendicular and of constant diameter over a certain length to facilitate the connection with the hose or other tubes. (if not soldered and therefore by clamp)
