Hello,
For a project I need to create a shape exactly like the picture I added. I've been trying to create it with solids or surfaces but I didn't succeed.
I've been searching in the PTC community and youtube but I didn't find the answer to my question, so now I'm trying this way. Can anyone help me to create this shape in Creo 2.0?
Thanks in advance,
Sander
You can do something close with a boundary blend. The same of the base will affect the shape of the dome and it may not be as smooth as your image shows.
See the attached Creo 2 model:
Looks like the top of a sphere squared off and drafted with rounds. My quick shot at a model is attached.
The part seems to be vacuum formed and I think the square frame is not with rounded corners.
My selection would be a warp feature with sculpt tool applied to a straight plate:
The result will be something like this:
Not very accurate but perhaps you get the idea.
EDIT: Creo 2 example file attached
Is this the chocolate you were thinking of? 
I like that I was able to make the top a revolved surf. Interesting.......
I blew some more air to my model by dragging the sculpt control points up and it looks like this.
Side view:
Reflection analysis:
Sander: would be nice to hear does any of these solutions meet your needs?
Does anyone remember the old Dome command. It was back on rev 17 - 19.
The command is still available. Need to add the following line to the config.pro:
allow_anatomic_features yes
Then type Dome in command search box.
There are two options: Radius Dome and Section Dome
Section Dome:
The radius dome doesn't look too well on reflection analysis:

The real question is this: How accurate does the part REALLY have to be? Antonius has an example of a beautifully smoooth "Dove" chocolate (I can't afford that high-end stuff, so I have to settle for the cheap "Crow" chocolates....LOL ), but is that kind of surfacing REALLY needed? The ID guys rant and whine about C2 this and that....all the while forgetting that in the REAL world (not the idealistic one), the parts you are going to actually get are the prize, not some reflection analysis the customer will never see. You can get 99% of those kinds of surfaces pretty easily, and then, as you ALWAYS do for cosmetic surfaces, specify them to the mold-maker as C2 surfaces. Done.
If this is an exercise where you're learning surfacing techniques and time is of no object, have fun and learn as much as you can. I learned a few new tricks doing this, and glad I pursued it.
If, on the other hand, you have a boss who has a deadline for you, well, I'd do the 99% solution, hand the ID guys a box of tissue if they complain, and tell the mold-maker to make it nice and C2 shiny-perfect.
But, maybe that's just me.....

LOL I thought while we were indulging in some digital eye "candy", I'd have some fun with it. I'll e-mail you the file, I decided to try something completely different. I believe I still have your offline e-mail. Hope ya been well!
