Hi, Peter,

Since you have reached the fourth image, the last step will be closing the hole in the middle.
You can try splitting the edge of the hole in halves and loft them.

If you want a really smooth solution. You can try polygon modeling.

Best,
Peng

Thanks Peng but if we can make cars whit this program then there must be a simple way to make this
but i keep yours in mind-

You will need to redraw the base, simply extrude edge from the surface I created…

Approach 2:

To create what you had you don’t need all those curves…

A simply command railrevolve can do that one step.

You only need 3 curves to get this kind of result.

Hi @peter1, See if this is what you’re after. Guide curves are on the red layer so you can adjust them and re-loft the surface to adjust it. Michael VS

I’m amazed that no one has recommended the fastest easiest and simplest solution. Solid boolean 2 objects and fillet the edge.

thanks guys for all your help i learn a lot from your solutions however there is only Jim who made it correct
because the top cover of the bread case is round everywhere there are no straight linen in it i think the made it
in the early day in a pressing machine first the make a mold etc…as a say jim did the job well i really like to know how he did it i made an example from jim and mine curves they are overdone but at the moment it is only practice to find out how it works

greetings Peter

[peter1]

i will give this a try soon
thanks Peter

[peter1]

this wan i did before but no good results
greetings Peter

I didn’t use your curves . I was trying to match the shapee that I saw in your photo which looked a lot different than your curves,

The enclosed file shows the basic steps.
