Copy Array Along Path tool...have a look.

some few more details of explanation:

-b)a curve divided by segments of a precise length.
. For I have to dispatch elements with a definite length along the path, it is going to remain an under sized segment from "Polyline Division". I delete this extra one before go further.

When I use "Perpendicular Face Tools" to put a face at each end of the curve, those faces are grouped. I ungroupe them in order to make them as available faces with "2Faces + Path".

ah i get it now simon, thank you very much for the written explaination.

thank you pav)

@pav_3j said:

i think one thing you may have missed out (as i understand it) is that the amount of steps you have to take with the 2 faces and a path tool, must equal the amount you have segmented the curve by, or the faces will not end up on the end point of each line.
correct?

"2Faces + Path" dispatch automatically the faces at each intersection in one pass. This is the very good point!!
It dispatches exactly (n+1) faces: a face at each intersection + a face at two endpoints of the curve.

So we have to delete the two previous faces we have put to initialize "2Faces + Path" process.

important remark: "Perpendicular Face Tools" and "2Faces + Path" doing the same, are dispatching the faces oriented at the mid angle between each two segments, and in a perpendicular angle for end lines..

another very interesting feature is the ability of this plug to dispatch faces as they are aligned to path or not aligned to path. I will show in another post how it can be interesting to mix invariant oriented elements with elements following the path like in a barrier, a suspension bridge...

Very clever Simon....I'll be trying this for sure!
thank you man! )

PS: I wonder if it would be possible to have a ruby called "Replace segment with Component"...nah....I doubt that could be written

@chris fullmer said:

Was TIG working on something that would replace a single line with a component and use the line scale and orientation to determine the scale and orientation of the component?

In this case I think that orienting a face is an easiest way than orienting a line !?

Should try that with Remus' catenary curve...

Bob James

Thank you Simon: I can really understand the process now.

However, you and I have a different definition of "fast and easy".

[plugin]Simple Catenary Curve
../ this is done.

Have a good night SCF fellows *s

Anyone care to figure out what I am doing wrong. Not quite sure the proper setting for the axis on the component...See attached.

Thanks,

That is great! I believe I understand. Basically, position the axis in the center so that the front and back end pivot at the same angle. I assume you just have the adjust the first and last component so they line up properly? Thanks again. I'll try it again. Merci Simon!

Cheers,

And drawing inspiration from this thread, I just wrote a quick little script called component stringer. You can download it here:

It does essentially what Simon is showing.

Hi Jeff (big work had taken me out of reply)

Thank you for trying. It is interesting because it shows me what I have to explain further (but it's a "WorkInProgress" also to me! ).

The very basic theory to understand is that our components are not aligned to segments of the curve but are drop on faces (perpendicularly ).

You have focused an important point: the first and last faces are perpendicular to first and last segment of the curve. So they represent a particular case. If we want a very precise result, we have to realign them with the same angle of the others

Second thing important to understand in doing this way: The process remain aproximativ . Not depending of the variations of the curve, the welding is "à peu près"!!

Your component was empty from axes and significant Construction Points. I have added them.

Your are right. The position of component's axes is absolutely fundamental. the good origin is pointed to be positioned on the apex of the triangles(?english~~)

Your curve, your component, your chain!

Thank you, Chris!

Hi Chris,

It's a great pleasure to discover that you were looking apart silently and suddenly come to drop a top cool tool! Component Stringer

You have decided to make the components follows the lines rather than faces.

Chris

The result is that this tool is wonderful for necklaces

And we have not to use it for imbricated components

One more time, many thanks to you dear Chris,

So, Jeff, how is that SketchUp model of Doc Ock coming along?

Click Draw

Hey Miguel,

I might be able to do the arms now but I'll still suck at modeling Doc Oc. I need to put way more hours in to organic shape modeling!!!

Hope everyones weekend is going well....

Cheers,

Have you tried importing a Make Human model into Wings 3D or Silo and tweaking there? Then you can import the Wings 3D model to SU and add the robotic arms.

Click Draw

I'll for sure check those out, thank you. I would still like to get decent at organic in Sketchup though. Here is a quick try at Chris's new ruby. I love it! Nice to be able to edit the component and see it update instantly. Thanks again Chris!

I pursue the study of my proceeding despite Chris's "Component Stringer" because for the moment(But Chris is working to the speed of the iron horse!!), I think I can master better -the welding of components imbricated, -the mix of various components along the path, _the mix of components following the path with components invariant in orientation.

Here is a realtime video (no editing) to show how fast is the process.
We start with a curve and a component.

Some help to produce the component to copy along a path.

I)Put the good axes:

If it is for you like for me , positionning axes of the component I want to copy along a path is not so evident.
So, make a cube, make it as a component, and......

II)How to conceive a chain link:
Using one or other method to produce a chain, necklace and many others fences and so on, you will need to think about the shape of the links.
Here is my tip. Just think to draw a portion of curve with the smallest radius you think you are going to use for your path...
