Need advise on Part Modeling (Bended Oval)

[teckchin83]

Hi,

I have model a bended oval part as image below.

 

May I know how to modify this 2 corner to 90° straight as shown in blue outline?

Thank you.

Hi JDMather,

Currently this parts I'm showing it will be molded and the dimension required 100% precisely.

The wall thickness in the sectional view of XZ and YZ was different.

So I can't use any command related to sweep and shell and have to draw the ellipse to create the oval layer by layer to create the differential of wall thickness.

The arc length "X" & "Y" is the most critical dimension of this part. 

Thank you

Initially I was started in all flat and all the bended dimension was correctly.

Now I'm trying another method, create the outer part and bend first then extrude and cut.

From there will cut out layer by layer and hopefully at the end I managed to chamfer the part. (I haven't try to chamfer bended part in Inventor before)

So is the vertical profile the same in the perpendicular x-section view?

If so, then you have a complex surface to make.

I was wondering about the x-section in the other direction.

Is there a slight draft on the o.s. walls too for mold release?

Hi Cadman777,

I'm was trying your method to workout the part. 

Yes, there is a slight draft with same angle on the outer side wall from another direction from X-section.

Only was the inner wall was different angle from the another direction from X-section.

Previously I was created 2 ellipse and loft to solved this.

Hi All,

Thanks for the brainstorming!

This is the final outcome with the required dimension for my project.

Can you Attach the “solution” here?

Thanx for the update.

I'm not sure I get what you're saying, but now worries. Usually with a challenge like this I sit down w/the customer and draw hand sketches to take back to the computer with me.

Anyways, looks like you solved it.

This is a perfect example of a surfacing challenge which requires a bit of head scratching to get it done.

Glad you got the result you wanted!
