cut out cavity along a path

[Anonymous]

Any way or suggestion on how to cut out a cavity in a shape with different heights. The Loft and Sloping path make it difficult.

Sketch 1 (sketch lines in Red) shows the cavity i want to create.Can this cavity be created by Shell or some other method?

Basically Shell out a cavity below Extrusion1 to Sculpt 2 using the Sketch 1 Red Lines as the shape guide of the required cavity.

Is this possible ?

A 2013 file is attached but i can view 2015 file if required

Thanks

Didn't study it in detail but doesn't that just need a revolve (cut)?

Looks like you're trying to have the "top" of the cavity follow some fixed distance from the bottom of the channel above, yes?

If so, I'd Revolve the existing cavity profile you've got to make the "base" of the cavity, then Sweep a separate, rectangular profile along a path that follows your existing ramp.  I'd probably make that new path as a 3D sketch by intersecting LoftSrf1 with the exterior cylindrical surface of the part.

Hope that helps!

Thanks.

How would you cut out the sections in blue?...i got the bottom outer section to be 6mm wall but had trouble getting the blue sketch areas to be shelled.

How would you do this?

Thanks

How would I do this?  I would start over from scratch.  Interesting problem, and you have come a long ways, but unfortunately I don't have a lot of time during warm weather (have to go outside and beat back the jungle from overtaking my yard) to tackle complex problems like this.  It is also difficult to guess where you want to end with the design as it morphs.

I would also have to start asking a lot of questions about manufacturing processes for Design for Manufacturability consideratons....

No easy button solution...

I was thinking of restarting. In fact i will and see how i go

Thanks again

My students are always resistant to starting over after putting so much work into something.

But I think you will find it goes much easier and quicker than you might think.

I am sure you learned plenty from your earlier attempts that you can now clean up and make a more elegant solution.

I like watching how these designs progress - be sure to post back.

When you get to a "final solution" I might be motivated to show how I would do the part from scratch.

Trying a different approach.The model picture of a .ipt is 1 attempt but i thought i wouild try surfaces

1. How do i remove the 2 surface faces? ( i did remove them but use a few planes but i am hoping there is a simpler way)

2. Can i then turn the surface shape into a 5mm thickness to the inside? ( i am thinking maybe stitch/thicken or sculpt??)

The part is saved as 2013 but i can view in 2015

I would like to have a finished solution in the next couple of days

Thanks

Will this be manufactured as a single part or as an assembly of parts?

It would be assembly of parts.

I want to make as a single part though...would you use multi-solid bodies and then combine to make as 1 part ( a.ipt file)....could be pushed out to an assembly...

What are your thoughts on the way to model

Thanks again

I have sketch 1 set to be used for multi solid bodies from the last posted .ipt model (test part 3)

Just for learning purposes how would you perform the following?

1. How do i remove the 2 surface faces? ( i did remove them but use a few planes but i am hoping there is a simpler way)

2. Can i then turn the surface shape into a 5mm thickness to the inside? ( i am thinking maybe stitch/thicken or sculpt??)

The part is saved as 2013 (last posted surface model) but i can view in 2015

Thanks

In this test example Sketch 11 is a guide for Loft 3. Although close Loft 3 is not aligning with Revolution 2 and Loft 1. What method do i use to correct this?

I have 1 more area to fix after this which i will attempt to solve. If i can solve i will redo the part and post a final model.

File attached is 2013 but can access 2015 files
