How to extrude a shape over non parallel body

[Anonymous]

I'm new to CAD and Fusion 360.  I have watched a couple hours of tutorials on YouTube and the Fusion site.  But I still cannot figure how to extrude a shape over a non parallel body. 

Attached is a screenshot of the base I have constructed and a few snipes of the CAD drawing I'm trying to accomplish.

Any help appreciated.  I have been working on this for a couple of days on and off.

base.png is my Fusion 360 sketch

sideProfile.png is CAD drawing side profile

front_profile.png is CAD drawing front profile.

I'm not 100% sure I understand your question, but here are a couple of ways to approach the basic shape.

The first is closer to your current approach.  Starting with your base profile, just create an extrude that is bigger than you need, then cut away the part you don't need:

The second is to do the extrude, not from the base profile you have now, but from the "end" of the shape (the side with the curve to it).  Basically, create the shape, then go back and add more detail.  Here is that approach:

These are very simple videos, they don't contain the detail you have in your model, hopefully you can extrapolate from them to get the results you want.

Jeff,

Thanks for the quick reply. 

I tried the first method and it will not work for what I'm trying to do.  The end of the arcs must match the base profile extrude.  I cant trim away the extra because the profile will not match the original CAD drawing.  

You may be able to tell that my base tapers from the front view to the back view. 

If you are still willing to help I have attached another png file of what I'm trying to create.

Hi @Anonymous

I have attached a screen cast outlining what I think you are trying to do.

Hope this helps.

what @Anonymous shows here is the way I would approach this, as well.  Loft is a very useful tool for this kind of geometry.
