intersected cylinder development

[SILVIUM]

first of all a greeting to all,
I wanted to ask if someone knows how to expose a cylinder tangentially intersected by a snail. I'm practically talking about cylinders of filters with rectangular input arm.
I am trying in all manners, at least for those I know; loft,profiling, but I can't.
I wait for news on this

Can't open it... Can you save it in a slightly older version?

you can not,no solid modeler saves in previous versions.
in compensation for new users, it is good to show up in the appropriate section. .

I think you're right. I was so tied up to autocad that I missed this.
Maybe you could try with a step....or not...

I'm going to introduce myself!

I saw your attachment but I didn't understand much what you want to do.
I mean, do you want to make the mouth of the spiral that ends tangent to the surface of the cylinder; as if it were a cyclone of dust extraction?
If you confirm, I'll give you an example tomorrow morning.

 

[Tarkus]

to every good account, I put you the example...
I, when it comes to sheet metal bodies that intersect, I prefer a model of only surfaces that then comes into various components that I suspect. .
It's a bit gross, but it should put you on the right path.

tarkus, you have practically identified my question; only that in the tangential part to the cylinder the height changes, that is the upper facade is in the plane
instead the lower facade drops from 400 mm to 1100 mm.

If I understand correctly, the lower face of your input duct
It's overwhelmed. I mean, it's finally a helid.
If so, no development of that face.
inventor does not:
