I'm also waiting for a version that can do what you want...

Thanks Miguel,

Seems to work fine when the path is 2D by not when 3D. So far I have made a work around using the Radial Bending ruby....just more time consuming.

Cheers,

Jeff

Jeff, I made a request very similar to yours back in March. You might want to check the thread for some ideas people gave:

EDIT: Now that I think about it, perhaps a combination of 1001bit's extrude along sloping path + Chris Fullmer's Components to Faces could be the ticket.

My perpendicular face tools will do it. It just doesn't do it as an array. You have to click where you want each face to be applied. So it could be useful, but also tedious if you need a perfectly spaced array.

Hi Chris,

Ya...I used it in the sample above but I would for sure be very time consuming. I was wondering, each face is created as a group, could it be possible to have it place a component on a node instead of a circle, square or custom face. Kind of a combo between copy path and perp faces.... what do you think?

Thanks,

Jeff

This along awaited update of RickW's tool CopyAlongPath - to rotate as it copies... I'm do some other stuff that will involve an algorithm that could be applied to this - but don't hold your breath...

2D rotation works for components, but 3D rotation has yet to be implemented.

This will make a nice commercial script, Rick.

Jeff, I use perpendicular to path as well to do what you showed in your first posting, but it can be a tedious process.

If it could be automated AND combined with scale along a path from one object to a rescaled-copy of itself, it would sure be helpful in producing things such as reduced elbows.

Lets hope ...

"This along awaited update of RickW's tool CopyAlongPath" Yes indeed dear Rick, we agree with TIG. We need it! (we want it )

this is my try:

I'd like to experiment with changing or replacing the component with another. I think this will come in very useful for creating rope, chain, spine type shapes, etc....

Is your "easy and fast" the same eight-step process in your previous post or have you come up with a real "easy and fast"?

pav_3j · 10 Nov 2009, 23:44

simon you are a master of getting the best results using methods most don't think of!

i'm still a little confused by the process, but i'll get there!

pav

pav_3j · 11 Nov 2009, 02:37

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

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?

thank you again.

Very clever Simon....I'll be trying this for sure!

Thanks,

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 · 11 Nov 2009, 06:09

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? Something about that sounds familiar...

Chris

Click Draw · 11 Nov 2009, 06:26

I sure hope someone is working on something like that. That would be an awesome ruby. What you could model and the time saved would be great! My eyes will be glued to this thread...
Cheers....

Hi Bob and Pav,

I'm confused because in following my own idea I was sure to have described the process in its simplicity!! Your two comments tell enough I was wrong.

I am going to try to explain better , "pardon pour mon anglais".

I)My main idea is that we need to prepare the curve we intend to be the path along which we want to copy our elements. Because what we need is a curve made of
-a)an exact number of segments
or
-b)a curve divided by segments of a precise length.

1)If we make our "path" using arc tool or/and line tool or/and bezier spline we need to make it first a "clean curve". This is made by the help of "Weld".

2)Once this is accomplish, we are going to convert this curve as a well wanted segmented polyline. this is made with underknown features which go with "BezierSpline" . When you select the curve, you can choose by right-clic context menu Convert to: Polyline Divider (if you wish to divide your curve by segments of exact length) or Polyline Segmentor (if you want to divide this curve by a specific number of equals segments.)

II)My second idea is to use "2Faces + Path" plugin in an unusual way. This plug is first intending to drive a transformation from a face to another one. My idea is to use it with no transformation! the first and the last face are the same! So this face is going to be dispatched in one clic all along the path in between the segments.
Re: to simplify the process I use "Perpendicular Face tools" to put in place with a clic those first and last faces, but we can do without it. (in particular when we want to use a complex face)

III)My third idea is to use "Components onto Faces" to replace those faces by the component I want. One more time in just a clic and, as the faces remain selected, I can delete them with one push on "Del" .
Re: if I want to dispatch various components like in the case of my chain, I copy the same number of the path+faces and I delete by hand the faces I don't want to follow the component. And I assemble them at the end.
Re: the main tip is to play foxy with "modify axes" inside components.

In summary:

1)drawing the curve
2)make it clean (weld)
3)make it a divided polyline (BezierSpline: Polyline Divider or Segmentor)
4)put the first an last face (Perpendicular face tools)
5)put a face at each segment intersection (2Faces + Path)
6)replace faces by components.

(I have some others ideas to develop the process, I shall tell latter )

simon.
