Lofted surface transition

When creating a loft between two curves, I am not able to control the top and bottom portion of the surface created, I have joined a picture of the part and my IPT file with the problem I got.

 

Thank you for your help.

Don't loft, rather sweep the two profiles, and then shell them to obtain the correct thickness.

Hi Daniel,

please find a sample of the desired part attached. It was build with the 2009 Version of Inventor so you should be able to open it.

 

cheers

Thank you for your solution, but in my part there are three differents sketchs at each end and the top of the part is not flat. That's why I used surfaces to create the curved top.

 

Thank you.

Daniel,

 

I took a quick look at the model. I personally think this can be done easily by extruding a Y-shape profile. Then draft side faces. Would it work better?

Thanks!

Here is a quick attempt.

I think I would use some 3D intersection rails to get it correct.

Your sketches were too complicated for me - edit your first sketch and see how I simplified it.

See attached attempt. The surface looks OK, but I cannot make a solid of it.

Here is another attempt.

I might use this as a guide to start over.

And a variation on Walter's - but I didn't really like the fillets.

Thank you very much M. Mather

 

I agree with you about the simplicity of the sketchs. This part was originally modeled with Catia and I have tried to use the same dimensioning that I found on the original drawing.

 

Your solution #1 is more acceptable to me because I need a shell thickness of .05 inch. In your rev. 1, I am unable to create a shell as low as .001 inch.

 

I think it would be simpler if I had better control of the lofted surface in my original IPT file.

I'm sure if you used rails you could get better results and should be able to shell to any thickness down to where the fillets (which I would do as fillet features, rather than sketch fillets) near zero radius.

 

Give it another try and if you don't get better results I will see if I can find time to improve the part.
