Please don't... Stick around until the point you will be able to help others as others helped you.
The cycle must not stop
haha, right! I have a feeling I will be posting quite often... Sketchup is such a fun program to learn and even more so when you have people helping you when you get stuck!

The pattern isn't right but it was a 15 minute doodle.
Using a single plugin: shape bender...
JQL, how did you go from the step on the right to the one on the left?
Also, your final shape has quite a bit of overlap. I assume this is not ideal for a 3d print. Curious.

I used shape bender using the arc of rhe pie.
In the end there's cleaning up to do to reach the last step as shape bender wasn't able to compress the bottom center part to an edge.

I have used Shape Bender many times but not sure I fully get this part. Fully comprehend doing the curve to obtain the shape of the vessel but do not fully comprehend how to perform the taper.

When I bend my shape many of my petal cutouts get messed up, do you think it could be because I am working in real scale and I should start larger and then shrink it down? Yours stayed so perfect!
My real scale is bottom c=22cm top c=64cm height 24cm

That should be the issue. Try scaling it up by 10 and then 10 again until Shape Bender doesn't cause issues.

The trick with shape bender is that the edge that is parallel with the component, must be in the vertical projection of the component's X axis. Then you can control the final result precisely like this (click the gif):

Check the following gif.

I was just struggling with that part. Great how you used the bend tool again to create that triangular shape at the end. Lets see if I can pull it off now... lol

This is great JQL however when you have to trim the edges because of the overlap the original pattern is destroyed. I have been struggling with the right angle to make the shape "wedge" to a point so no trimming is necessary.

What if you trim the shape at the beginning with the original strip. Starting the trim at the same spot the shape starts to bend and then ending it at the width for the bottom circle ratio. It would possibly give a bit more control over the scaling of the pattern but the angle would only work if it was a uniform arc. Is this right?

Share your model at the same stage boofredlay, I'm sure there is a solution.

Well I am making progress but still issues that seem a bit too complicated for me to figure out. Maybe I need a more simple pattern.

Here you go but as you can see, the edges will never taper properly to a point. The repeating pattern is destroyed each time. I think the method I used originally works much better, slower but more accurate.

I'd say you need a simpler section of that pattern. What you could do is probably make a section of half the pattern and then mirror it, create a section component and polar array it with the rotate tool.

I'm sure you're right, but I'll give it a shot anyway.

Still making progress, I got my geometry all figured out, just need to accept the fact that I have to change the pattern as I go down. Maybe just a few simple leaves going back and forth for design and then of course I have to punch the holes. I am happy I got the pattern even just 2 rows of it at the top. Also hoping that I can round it off after I am done so it doesn't look so jagged.
Thanks again for your help and ideas, they have been very helpful! Still not done but getting there!
