A trivial 'real world' nod to produce a printable circular funnel.
As an example I've chosen sizes to match a funnel I made some years ago to facilitate loading peppercorns into a pepper grinder.

Welcome to the Elephant
World...... Mike.
Perhaps, for such a simple object, I think that,
start with a profile, then create a revolution
is the best method ....
Maybe many less Nod ???? ...
In every case appreciable

Hello Mike,

it makes me happy to see the different aspects of the application. Especially when the results will end in real world parts. Methods and complexity will automatically increase. And used in the right place, productivity will also increase:-)

Have a nice day

Thanks for the suggestion, Al, I'll think about it.
Mike.

Thanks, Karsten. I have plans to increase complexity by making a nod for a 'universal' funnel. That is, a funnel that has square round elements.
Mike.

Hi Karsten,

I am happy to see you back on the forum & hope you are well.

I wonder if you wanted to have a play around with something node-wise,
if you could have a look at extending your text node, so that it could be utilised
for numbering pt arrays as per my earlier posts:

This would be a real boon for the more complex indexing of arrays.

If you could, I would be forever in your debt!

A more ambitious - and complex - funnel nod. The 'universal funnel'.
This nod is based on rounded rectangles so the top, middle and bottom sections can be rectangular, square or round.
Mike.

Hello James,

it is a little bit complicated to integrate the functionality into one node, possible, but not useful in my opinion - so I made a additional one. Please test it and give a feedback.




Have a nice day

Hi, Karsten, looks wonderfully good to me.

Tiny, tiny typo in both the Numbering and Text nodes you have the label 'Bolt' - should of course be 'Bold'.

Mike.

Another perhaps useful nod. Bottle square or round.nod
The output is five solids. I left them separate rather than using 'Union' inside the nod as I thought that the output would be slightly more convenient in that form, though I'm having second thoughts as I type this!

Below shows that sort of bottles that can be produced with the nod. It will not generate oval bottles.
NOTE that the neck is plain - required threads or bead have to be generated separately.
Mike.

Hello Mike,

it looks like you're having fun:-)

and thank you for your note. I'm not a native speaker, so any improvement is welcome. Here is a corrected version.

thanks and have a nice day
Karsten

Thanks for the warning, James.
Mike.

Hi, guys, is there a simple way of getting the x,y,z values of the last point calculated by MathPts?

Mike.

Hi Mike,

>> x,y,z values of the last point calculated by MathPts <<

MathPts "f(uv)"input into "InPts" ArrayExt/idxSelect node
Multiply Unum X Vnum minus 1 for input into "idx" on ArrayExt/idxSelect node
then "Out" input into Points2/splitPt to get x,y,z values.

An alternative is to use ArrayExt/ArrayFlipper to idSelect with index of 0

If this does not make sense, upload your file & I modify it

Cheers
James

Thanks, James. That's certainly a more elegant method than the work around I was using.
However... right now it's not giving quite the same result. I'll try and figure out where I've gone wrong tomorrow.

Mike.

Hi Mike,

I have attached nod file showing both methods.
Red & Blue sphere are used as placeholders to
demonstrate location set by xyz of arrays last point.

basic/length node as used for point numbering above
could be used instead of math node multiplying U & V values.

James

Thanks, again.

Well, I don't know what I was doing wrong, but in the cold light of day both the array techniques you suggested now seem to work just fine.

Onwards and upwards.

Mike.

Hello Mike,

please check also the RMB on the idxSelect node - you can also Switch it to the selection of values in numarrays or geometry of objectlists.

Have a nice day
Karsten
