how to get the ends of the coil to meet each end

[James__S]

Hi

Not sure i have used correct modelling technique here but can the ends of the Coil join each section which looks natural.I have not been able to get the ends to smoothly join with the coil feature

Best Regards

James

Your part gives me errors when I try to open it up. Please suppress the feature thats got the error and resend the file so I could look at the part

[James__S]

Thanking you...i rolled up the EOP.....please let me know if this still does not work

[JoAnn_Hogan]

Are you looking for something like this?

[JoAnn_Hogan]

Sorry I forgot the Attachment. I moved the EOP up

Hi

Yes thank you close.Can the Coil where they start at each end run along the edge.There is a sketch in black which shows how each end starts.Not have the ends of the coil revolving into towards the centre at the start

Thanks

[JoAnn_Hogan]

This is the closest I could get it.

[James__S]

thank you

It would be difficult to get it closer to the edge...thank you for help

How about exactly on the edge?  Take a good look at the sketch for the coil, the last extrusion, and the model parameters to see how to get an exact fit.

Thanks...can the start of the coil also run on the edge...not sure if possible but i was not successful

Thanks

Quite probably, but that's getting a bit beyond me.

J. D. Mather may be a better resource for surface modelling like that.

[James__S]

Surface modelling will be needed to create this shape.I too unfortunately don`t know how to surface model....maybe the shape is not possible

Wrong attitude to approach the problem.

If you had a block of clay in front of you - could you sculpt the geometry?

[JDMather]

The second question would be, "How will you manufacture the geometry if you can sculpt it?"

[James__S]

I would think a mold for this plastic part.

Thanks

You can use a Lofted "Revolve" for the last part where you start with a round matching the end of the coil and end with an elipse with a width of the coil and a height of almost zero. See the attached ipt for an example.

Thanks Rob

Good example

Cheers
