How can i create a ribbed surface on a rounded object

[Thunderpal]

Hi Together,

I’m quite new to Shapr3D and have some problems for creating surfaces to objects.

I’d like to make such a ribbed surface but all my tries failed:

I tried making a projection of a sketch to the surface but it will only extrude to the same hight around the opject and when i then try to fillet is not the result i want. also when i try to pattern this around the model it always tells me that the resulting body is invalid.

thanks in advance for your inputs.

Think of it as 5 bodies.

To make the main body: Sketch the bottom shape (circles around a larger circle, trim tool the unneeded line segment bits away). Then use the move tool to copy the sketch while moving it up to about the mid section AND then scale it larger. Repeat that Copy/Move again to the top AND scale it smaller. Then use the loft tool to loft the 3 sketches.

Do the same for the head section.

Another similar method that you can look at here:

Folded-like shape

I imported the twisted star shape from Corel Draw as a DFX. I selected it and used the “move tool” to copy, move it up and then rotate the copy. I repeated that several times, also using the “scale tool” to scale each copy. Then I selected the bottom star shape and “lofted” it to the other copies above it. I was simply testing shapr at the time to see what it could do and turned out pretty good so I printed it

I used the first method here Planter/Pot
