Problem With LOFT

[vertical horizons]

Whenever I use the LOFT command, the finished product has a seam (for lack of a better word) on the upper portion of the item. I don't know what I am doing wrong.

Any ideas?

I would be more concerned about the flat dip at the top. Before I suggest an alternate technique - do you really want this flat and dip?

Hi,

 

Question - why are you using the loft command, instead of revolve? The dip at the top is caused by the fact that you cannot get an arc tangent to both sections of the geometry that you have used.

I wanted it to be flat, but I didn't want to have the dip in it.

You are right.

I should have used REVOLVE instead of LOFT.

Exactly - please note the tangency constraints JD has used.

I can't open your attachment.

Did you create it using IV 2011?

See attached image of sketch.

Hi,

 

Unfortunately, JD's image does not show that the arcs are tangent to each other and that the larger of the two is tangent to the top 1/2in Dia circle. Tangency is crucial to a smooth transition.
