Complex Tapered Sweep Up To a Point NEED HELP

[rbengston74]

Hello, I am needing help creating a tapered sweep profile. I have the basic geometry laid out on the far right pocket but have had no success shaping it the way I want. 

My first issue is I cant move the outside pocket sketches down -.045 in the Z Axis which is where the top of the surface needs to be to connect to the other portion of the inner pocket. 

The depth of the big part of the outside pockets needs to start at -.320 and they all need to sweep up to -.045 where the pockets get smaller. The outside edge needs to start with a .250 radius in the corner and finish at a .0625. The spline in the bottom of the right profile roughly shows that. 

The angle on the inside of the pocket needs to maintain around 36 degrees. You can see that in my last sketch.  Also, you can see this similar design if you turn on visibility on the inner profile. Basically this one sweeps up to a small radius of .0625. 

The point of where the pockets start needs to have a much more steep angle down to the mold point on the bottom of the profile. I tried to show this with lines going down to the .250 diameter hole. There basically needs to be a radius there. 

All three have similar starting and ending geometry but have different paths. Same angle and bottom radius profile though. 

The closest I have come to success (haha) is when I first extruded the profile down -.320 and set my taper to -45. It basically had the shape I wanted except the back wall that should have a radius in the bottom was tapered as well. Now I cant even get this to work. 

I would appreciate any help at all, this is literally my first fusion 3560 project. I've included some screen shots and my fusion file for this. Email me @ rbengston74@gmail.com or text or call at  6207556151 any time.

do you have a photo or drawing of the desired outcome geometry?  If you are going to a point, I would be tempted to use Loft instead of Sweep, but it's hard to say without more information.

That's kinda where I was headed as well. I know loft is really powerful but
I have been fighting it. I will send you a better exmple tomorrow of the
design I am looking for. Sorry I was in a rush tonight. If you look at the
inside object you will see the type of angle I am after, but the only
difference is this one has to maintaine that angle while sweeping up to the
smaller radius at the small end.

hello @rbengston74  -- as i see the matter you have several obvious problems.

first sin too many points on the path.

secondly, only the small diameter and the overhead contour element with a closed profile.

Thirdly, the path to the center of the small hole does not intersect the diameter of the circle - so it is not suitable as a path.

fourthly there is a curved line that ends somewhere - should this also be used? somehow? ---

please enter all pictures with that kamerasymbol in the middle her.  greetings from mango

Here are some photos of a much similar mold from this design. Not quite as curved though, and I am wanting this new design to be a little more gradually swept up to the point. Thank you for the advise, I will remove some of the points.

Here is my recent progress on the pocket. Its not perfect but close. I made the sweep just by using 3d sketch and holding the line command. Now it wont let me use the loft command for some reason. Is there a more precise way to achieve what I'm looking for?

Hello, I have made a little progress today. Now I want to shell it out to .001 so I can machine it. Is there a better way to do this? I basically lofted all my sections together to create this image, which is the design I want but I need to be able to machine that part into a plate. Thank you for all advise everyone, it is much appreciated.
