Hi Mike, glad you're set up ok now. Having more than one instance running can cause problems with setting up shortcut keys since the moi.ini file will get written at program shutdown time and so the last exited instance will be the one that ends up actually setting the moi.ini file. So yeah when getting things like this set up it's a good idea to exit other instances but once it's all set up you should be fine to use it with multiple instances.

Got it.

Thanks.

Hi Mike,
your job is very appreciates ;
remember, however:that
omitting Math formulas that do not everybody Know
, and , Using elementary geometric elements
Such ,curves, polygon ,circles ,etc.etc
And using Elephant ;
Not only do you get the desired result, but you can
using the parameters used, modify it as you like
And why not, re-use it in successive jobs-
Furthermore make the result more understandable
reached ...
what do you think about it...
In some cases, believe me, as with Moebius
The goal is very easy-

Then concluding We urge you to begin with
Know Elephant-
Have a nice day

One more thought, is your setting in moi.ini "DisableFileCaching=y" ?
- Brian

---

Al I'm going to! Really!
I've already found 'Project Elephant's UNOFFICIAL Repository' and will dive right in

---

Just checked, Brian, and the answer is no.
I have: DisableFileCaching=n
Mike.

---

So modification of a .js script which has just been run in MoI, is not recognized until MoI is restarted.
(A more or less answer?)
- Brian

---

OK, Al, I've dived in.
As you wrote, the Basic Parametric Moebius.nod is wonderfully interactive. Most impressive.
However understanding how the nod was created is quite another story.
I'll read the Wiki.
Any other resources that you can recommend for a raw beginner?
Mike.

Hi Mike

The recommendations for a newbie are as follows:
-
Knowing theNode, and getting in touch with them,
Understand what inputs are accepted and output results, etc .etc.
-
See if similarities with other modelers
Nodal- (Grasshopper for Rhino ), (Dynamo for Autocad)
for instance
-
Use the files that have been posted to the Forum
By me, by James, by Karsten etc etc
To understand the various steps and the results obtained

Lastly, persevere without being discouraged and beginning to think
to parametric modeling, planning the various phases
to reach the target...
My goal is "less it's more" but believe me not always and easy
succeed
Good depth
We'll talk with all , after the holidays..........
Greetings to you and all the friends of Forun

Al, Thank you for getting me started with Elephant.

I've been studying your Basic Parametric Moebius.nod and finding it difficult to understand how it could produce a solid Moebius strip when my many attempts to do so (outside of Elephant) have failed when using Loft to make the complete strip in one go.

Eventually - it took a while - I realised that your node is not producing a solid Moebius strip - with only one surface - but a strip with two surfaces. See below.
Did you also do the moebius.nod? No problem with the strips in that however I've temporarily given up trying to fully understand the nod - it's too complex for me at the moment.
Mike.

Hi.

Just stumbled over this information ...

https://mathematica.stackexchange.com/questions/72203/can-mathematica-solve-plateaus-problem-finding-a-minimal-surface-with-specifie

... which may be of interest for marh magician Brian ..

Hi Mike
By reading your observations, I have checked again
the file I sent, actually something is wrong,
the profiles, which are dorsal oriented that determine the volume
are badly oriented and thus produce a final screwing,
I've reviewed the file that you find at this link:
http://www.mediafire.com/file/9u89bmm8b6lfgyj/Rev-Solidify_Moebius_Strip.rar
I also added some pictures that will make you better
the question...
In the end however, as you see the result is a solid one
best

HyperbolicParaboloid1:
_FxGraph3D u;v;u*v;-1;1;-1;1;50;50;0;0;0;UV

HyperbolicParaboloid2:
_FxGraph3D a*(u+v);b*(u-v);u*v;-1;1;-1;1;50;50;1.618;1;0;UV

HyperbolicParaboloid3:
_FxGraph3D (u);(v);c*((u*u)/(a*a) - (v*v)/(b*b));-1;1;-1;1;50;50;1.618;1;1;UV

HyperbolicParaboloid4:
_FxGraph3D (u);(v)/(sqrt(1+a*a*u*u));v*a*u/(sqrt(1+a*a*u*u));-1;1;-1;1;50;50;1;1;1;UV

Trefoil2_3FourierKnot:

_FxGraph3D cos(2*u);cos(3*u + PI/4);cos(2*u + PI/2)+cos(u + PI/6);0;6.283185;0;0;200;0;1;0;1;UV

Note, there is a small space in the unclosed curve, locate-able by _MarkOpenCurveStart, or MarkCurveStart, or MarkCurveEnd script.
Trimming the curve with a point at say (0,-1,z), and blending the gap, will make a closed curve.

Bohemian Stars (Torolf/jotero):
_FxGraph3D cos(a*u)*cos(v) + b *cos(u);sin(v);-sin(a*u)*cos(v) + b*sin(u);0;6.283185;0;6.283185;100;10;1.5;1.1;0;SrfU

This is one version. Parameters "a" and "b" make a big difference.

- Brian

Brian - fascinating.
The fine adjustment now available on the slider node made me wonder whether a nod for this would help to explore the effects of changes to a and b.
BTW with the example shown below I made into a solid via extrusion of 0.1mm.

Impressive node, Mike.

I may try a 2d slider for a and b.
Got to do a Mod version of Max's release .94...
Just copied the extension directory of Mod version to Max's release 0.94, nodes directory.
Mouse wheel works on sliders & knobs.


- Brian

---

Ah, yes, that new feature in 0.94 plus the later interface.js (see 7713.620) was what inspired me.

Mike.

Viviani's curve:

_FxGraph3D a*(1+cos(v));a*(sin(v));2*a*(sin(0.5*v));0;1;-6.2831853;6.2831853;0;200;0.5;0;0;UV

I plan to do a sphere sweep on this curve.

- Brian

Doe this work with V.4.0?
