Lofting issues

[wormpower32]

I am trying to create a loft on both sides of this design, 1 can get one side to loft but doing the exact same thing on the other side but it wont loft. what am i missing?

Please export your design in .f3d format and attach it to the next post. Then we can analyze it and perhaps provide feedback.

heres the file

I am not sure that a 2nd loft would create what you are looking for. Can you explain, perhaps even with a pencil sketch what you are trying to create ?

[wormpower32]

Im trying to loft the 2 rectangle openings into the round. then shell the loft to create airflow from the rectangle to round outlet. if that makes sense

[TrippyLighting · Accepted solution]

Is this close to what you are trying to create ?

[wormpower32]

Yes

What if you just mirror the loft?

[wormpower32]

How would i adjust the wall thickness of the loft? Ive always used shell

[TrippyLighting]

You can and should use the shell function if you need consistent wall thickness. To get a nice looking and functioning model, however you need to clean up your hacky workflow 😉

Otherwise the transition from the rectangular opening to the loft is going to look ugly.

I will openly admit that I struggle when it comes to CAD, Fusion is in my experience the easiest to use. But I am a beginner! Looks at this stage don't really matter compared to can it 3D print, and does it work? anything beyond that again at this stage is out of my abilities currently.

I am very grateful for your help and guidance with this.

@TrippyLighting Do you mind if i ask what it was that stopped the loft from working on my design?

I am trying to clean up the design, but every time i try to do the 2nd loft it errors out, 1 sides easy to loft. cant mirror as someone suggested  as you end up with a block path on both sides of the design.

I have attached the updated design, if you could explain what im doing wrong id gladly take any guidance you have.

[TrippyLighting]

I have no idea what you want to accomplish with the 2nd loft or even a mirrored loft.

What a 2nd loft creates is intersecting surfaces and Fusion 360 does not allow that for good reasons. 

This can be done with a single loft with rails. In the attached file I sketched the inside dimension and then shelled to the outside.

That provided a very clean connection  between the loft and the rectangular base plate.

Go through the timeline step by step and ask question if something is unclear. The only sketch that might need explanation is the sketch with the rails. It is a 3D sketch where I simply connected points between the upper and lower loft profiles. The rails are needed to get a symmetric loft.

The intention here is to create a vent for a PSU. So end game would be the base rectangle to say a 4” circle. Just to direct the hot air away from the PSU.
I’ve had other designs going from 2 circles to one circle via loft. Then shell. And it leaves a very affective design.

You can Loft both sides, but I changed order of operations, 

Change the first Loft to New Body.

Mirror that Lofted body as Join, with lower plate hidden.

Edit the Shell, and include the bottom 2 rectangular surfaces - to being selected.

Combine > Join the plates, if that's what you need.

Wondering how a bolt / screw can be installed in this hole.

Might help,,,,
