Sweep with Guide?

[RKCADSERV]

Hi All,

I'm after some advice on which is the best way to model the attached drawing. I've tried using a sweep along a guide but can't get the desired result!

Does anyone have any ideas (or example) thay might like to share?

Thanks for any help in advance.

Regards,

Rob K

Attach the ipt file here of your attempt.

Search here on wavy washer.  (this problem has been covered here many times in the past.

Many thanks for your reply. I have looked up the wave washer discussion and I can now complete the model I was looking at.

Hi

Just saw this this, so I thought I would give it a try. (Using the sweep)

See attached.

 Hi rhasell,

Thanks for your feedback. I like the way you have constructed the part. One more silly question! I understand the construction but how have you actually put the 3D curve in there (what commands)?

I'll have a play around to see if I can get there by myself but if you'd wanna share then that would be great.

Thanks for your help.

Regards,

Looks like a spline created in 3D sketch.

I might have simply done a 3D intersection - no extra workplanes required.

3 2d sketches rather than 4

see attached.

or a solution with only 2 2d sketches rather than 4.

Hi

Create the base sketch with req OD of 25mm with 2 points top and bottom.

Created a point for a workplane @ 20mm radius.

Created the workplane at above point.

Create sketch on workplane, create 2 points, left and right.

Create 3D sketch, create a spline between the 4 points, changed the spline fit method to "Minimum energy"

Create the sweep profile sketch.

Sweep the part.

I had a look ad JD methods, all good, just different ways of doing it.

The 3D curve is different.

Thats what I love about Inventor as well as the forums, there is often more than one way to model a part, and when more than one person contributes, that's how we learn (Or at least I have) the different aspects and features of the software.

I did not even consider a 3d intersection, and will store that in the memory banks for future use.
