Smoothing faces of a loft (square to round shape)

Inv 14

 

When I make a loft, from a 12x12 square to an 8" circle (12" high for the sake of arguement), the corners of the square kind of loft up to the circle where it's corners would be...leaving a sharp break between the planes

 

Is there a way to make it look like the sheet metal lofted flange appears? So that the corners of the square drift to the quadrants of the circle, making a smooth transition?

An example (picture) of your problem woul dprovide great help to anybody thinking about helping you.

 

If I understand the problem correctly, why not do the loft as a sheet metal part if that is the result you want? Other than that adjusting the 2 sketches will also give different results.

 

An example and direction to your requirements would be best for futher help.

Attach your attempt here.

It is not clear what you are after.

I want the solid loft to look like a smooth transitioning lofted flange. Not the current loft where you can visibly see the breaks in planes.

 

PDF's attached

 

thanks in advance

Try adding fillets to the corners of your square...

I almost said I didn't want fillets but deleted it...should have left it :smileywink:

 

If I put fillets on there it doesn't give me the same geometry...it just adds something else to something that isn't corrrect to begin with. It's the shape I'm looking for, with the corners of the square smoothly transitioning to the circle quadrants...not just a smoothness of the corners per se. The corners shouldn't be there.

Here is a snipped screen capture of the images you posted.

>The corners shouldn't be there.

Do you want corners or fillets?

Let me work up another example.

Maybe you can find an image somewhere on the web of what you really want.

That's not a fillet though...here is a fillet of the loft. It clearly doesn't look like the geometry of the lofted flange...I put edges on it to make it a bit more clear.

 

The fillet you're highlighting is a product of the metal thickness in the sheet metal lofted flange...it will get larger or smaller depending on the thickness...that image was .120.

 

If I went to some tiny number and that bottom corner was almost to a point with no bend radius...the corner would still travel to the circle quadrants and not to the "corners" of the circle as it does with the loft.

 

Again...I'm looking for the overall object shape...not just a "rounded" corner.

the lofted flange shape IS what I want...just imagine it without the metal thickness subtracked from it.

So remove the metal thickness subtracted from it.
Back in a minute - check this in the meantime.
