Different methods result in different final shape.

I posted this drawing couple of days ago and people helped me with modeling that. However someone used another method which resulted in almost similar outcome, but if looked closely they are definitely not the same. I attached both Parts; you can check how they are different, both in final shapes and sketches.

Which one is the correct way according to the drawing?

I do not have Solidworks here (so I couldn't open your models).

Here follows the process I used in Inventor. Should be the same...

Glad it was of some use :).

Yes, normally the different ways could give you the same result. What throws us in this example is the "23,9" dimension - which is actually rounded to one decimal. Then you will only get "close" if you use that.

(You can't always figure out why there are differences...)

Thanks Wilhelm, yes that is the exact way I was told about in my previous post.

However we can make similar pattern with another sketch too,although there is slight change in final shape.( compare 1.JPG and 2.JPG)

But I guess usually it is not the case and different methods results in the same result.
