Does exist something for this?
A sort of sweep...
Maybe there is something evident but...don't remember what :(
Of course the 2 lines inclined with points on the cube can be any complex curvated curves :)
(it's just the concept)

Hi Pilou, do you mean you want to put a surface between those 2 curves? If so then you can use Loft to do that.

If you mean you want to build lines between 2 curves, there is not anything set up to do that automatically, you need to just draw the lines.

But you could try building a surface with Loft, then use Rhino to extract isoparms of the loft surface, that may help you for that particular case if you want some large quantity of those kinds of lines for some kind of special purpose.

Yes!

In fact all the points of each curves are given
It just to trace a line between them point by point :)
The curious thing is that statement seems very simple

Command "Connect points" can't make that?

Of course for this particular form I can draw it easily in project some lines to the surface, for have the second layer of lines but for complex curves that is another story :)

Hi Pilou,

> Command "Connect points" can't make that?

No, that does something different - it's oriented towards making lines between the points that are closest to one another.

So for the kind of arrangement that you have there, it could probably build a set of lines around the outer boundary of your shape, it would not create lines that go all the way across to the opposite side of the shape.


It would be very difficult for program code to look at all your points there and understand which ones to connect up - remember that a program does not really have human intelligence and the ability to easily recognize patterns like that.


It would probably be possible to create a script that would generate points by doing an array on curve and then draw lines between those points. That would give the program some kind of structure and ordering to the points that it could use, rather than just having some big pile of points. But there could be some details that would be hard to get right in the script, like making sure that when you pick 2 curves that the points are going in the same direction on them instead of going in opposite directions.

If you want to try to make a script like that, Petr's "ReconstructCurves" script would be a good starting point, since it uses that same kind of technique of generating points by using array curve: http://kyticka.webzdarma.cz/3d/moi/#ReconstructCurve

I'm afraid that it's probably going to be complicated enough that I can't just create it for you myself though, sorry. I could try to help you with it if you get stuck in a particular thing though.


But this kind of automated construction process is probably something that you would create with some kind of scripting, you may want to look at Rhino's Grasshopper mechanism, it is a kind of node based scripting mechanism that makes it a bit easier to create automated constructions.

< But there could be some details that would be hard to get right in the script, like making sure that when you pick 2 curves that the points are going in the same direction on them instead of going in opposite directions.

If i make Trandform array /Curve with a point along a curve I give direction i want ? ;)
So not important
and each curve has the same numbers of points

< I'm afraid that it's probably going to be complicated enough that I can't just create it for you myself though, sorry.
No problem :)

Hi Pilou,

Well, remember I'm talking about doing the array as part of a script and not using it in the regular way.

But maybe the built in orientation in array curve will work ok for that anyway.

Maybe it won't be quite as difficult as what I thought, I'll give it a try later.


But if you want to make more kinds of crazy automated constructions, it becomes difficult for me to make special tools for each one of these myself, you probably need to learn scripting or learn to use Grasshopper if you want to make a lot of this kind of stuff.

- Michael

< you probably need to learn scripting
Sure :) I am thinking of "Processing" http://processing.org/discourse/yabb2/YaBB.pl
Seems perfect for that and very versatile ;)
see this guy ;)

Just that this function above is maybe pertinent or not for MOI : that is the question :)
As there is not yet "deformer", that is an easy way to simulate them

Hi Pilou,

> Just that this function above is maybe pertinent or

No, if I remember right Processing is for controlling what is drawn in a "canvas" element in a web browser, mostly with 2d drawing commands.

It's for generating an image result, not for controlling another program.

But you could definitely have a lot of fun with it!

- Michael

yes :)

but I was speaking of the eventual new function "connect points from curves" inside Moi ;)

Hi Pilou, try the attached plugin LineWeb.zip .

To install it, unzip and copy the 2 files into the \commands subfolder inside of MoI v2's main installation folder.

Then to launch it you can either type in <tab>lineweb<enter> or go to Options > Shortcut keys and set up a new shortcut key with LineWeb as the command name.

It will take a sequence of curves, if you have more than 2 click on them to select them in the order you want them connected. Then it produces stuff like this:






There is a point count option that you can adjust for how many connection points you want.

To get the kind of thing you were wanting, you would run it twice - first with 2 lines like this:





Then select just the outermost 2 lines that were just created and run it again:



Note that when you run it the second time, there will be some lines created right over top of the very original 2 lines so there will be duplicates there, you may want to delete those original lines after doing the first run through.

Hope this helps!


EDIT: Uploaded new LineWeb.zip, this updated version now has an option to build either lines, polylines, a smooth curve, or point objects.

EDIT2: Uploaded another new LineWeb.zip, this one now has a closed option to make a closed ring of lines or a closed curve.

Hey Rockey....Watch me pull a rabbit out of my hat!!! I like this one. :o

Oh, and if you get things connecting reversed like this:



then select just one of those original lines and run the Flip command on it, that should fix it after that.

- Michael

Thank you, Michael.

>Hey Rockey....Watch me pull a rabbit out of my hat!!! I like this one. :o

Yeah, he's good isn't he... :-O

Absolutly fabulous! :)

Sorry but my old monitor 17 inch has explosed with the heat! :(
So I must remanaged all icons and all progs for work on a 15 inchs second hand monitor!
It 's very usefull that the Moi UI can be adapted! (in my case decrease size :)

I will test your new task opus as soon as possible! ;)

Speedy test :)
Bravo!
Works like a charm! :)
A cool process can be
LineWeb / Extrude / Shell

Hi Pilou, I'm glad that works - cool idea with lines + extrude + shell! :)

Sounds like time for a new monitor?

- Michael

Yes I have it one but with less resolution
No problem, I make only miniatures :)

You have also funny results if you take in the same time all the sides curve!

it's very easy to make some funny wires without effort :)
