weld.rb problem

[Photonix]

Hey SU community,

I have the following problem using the weld.rb plugin:

I have to convert all edges of my model to closed polylines in a single step (the model is very complex) prior the dxf export for autocad.

Because I have nested geometries, the plugin does not work in the right way, I have added a simple test file. The plugin only works if I select the box and the text sequentially.

Is there a way to add some code to the weld.rb plugin to get it working with my geometry? My modell has ~4 million edges that have to get converted to closed curves (autocad polylines) with a single selection step.

Thanks in advance,

Marcel

Hi, Marcel:
Perhaps I did not understand your question.
I was able to close with weld the segments on the E and the S. Tracing over one of the segments on the E to form a face, I was able to extrude it up. The corners were hidden. I could trace along this corner, or use CTRL+Eraser+Shift to harden the edge. If you want to convert to polylines, you may want to try Fredo6's Bezier tool. With this tool, you should be able to right click on the welded figure, select convert to polyline, or several other possibilities.

EDIT: My apologies First of all, you posted in the Developer's Forum. I would not normally comment here. What you are requesting is an "en masse" welder. And one that dives down into nested groups and components. There may be technical issues here that I am not qualified on.
I can suggest ThomThom's Clean Up and Vertex Tools in the interim.

Thanks mitcorb,

you are right: I need "En Masse weld".

I already tried the plugins you proposed, without success.

Could anyone help please, its quite urgent.



@ forum moderator: could you please move the thread to the right forum section, thanks.

It is relatively simple to iterate a collection of edges and 'weld' them into connected curve 'sets', BUT if any of the edges 'branch' then 'weld' will fail to make a fully curve of all of the edges...
However, help might be at hand - have you looked at 'ReCurve' viewtopic.php?p=324196#p324196
This is perhaps more like you want ?

[Photonix]

I tried the recurve.rb plugin, without sucess.
It does not work with nested objects. Any other suggestion? Is anyone able to edit the weld.rb to run for nested closed lines as well?

[TIG]

Here's about as good as it gets...
You need to install both of these scripts into the Plugins folder and follow the TIG.weldall instructions to make every edge in the model a welded curve...

Name:-
TIG-weld.rb
Description:
Joins selected edges into a 'curve' (~"polyline").
Author:-
TIG - based heavily on RickW's 'weld.rb'...
[but no close/face, and also suitable to be called in other methods].
Usage:-
Make a selection which includes the edges to be joined.
Run the script from the menu:
Tools > Weld
or type in the Ruby Console:
TIG.weld +<enter>
Selected edges will then be 'welded' into a curve wherever possible.
Disconnected edges or branching edges might give unexpected results.
A curve will be split where any 'branching' edge intersects it.
The process is one step undoable.
To use the tool run within another method include...
require 'TIG-weld.rb'
and use
TIG.weld(true)
to supress 'undo' complications.
The calling method must make a selection of potential edges to process,
even if inside another context, perhaps iterated in turn,
see "TIG-weldall.rb" for an example...

TIG-weldall.rb
###
Welds ALL edges in a model [including any nested inside groups/component-
definitions] into curves.
Note that disconnected edges or branching edges will all become curves, but
some might be one segemnt long where a vertec has more than two edges...
Note: it requires script TIG-weld.rb loading too...
Usage: in the Ruby Console type, TIG.weldall +<enter>
It is one step undobale.

Thank You TIG,

it works fine, but needs a lot of time for my geometries.

Is it possible to speed it up or if not, to implement a progressbar?

It still runs 30mins for 200.000 edges, no end in sight. I will abort now.

I will try with 15.000 edges and post the needed time when its done.

[TIG]

If I could have sped it up I would have.
It has to iterate every edge in the model and all groups/definitions and then decide which go into which connected curve - it's complex stuff, I'd leave it running as long as you can - it'll beep when done.
A progress bar would only slow it further and as soon as it hits a limit it'll white-out anyway and stop updating it, giving the impression it's stalled when it is actually still processing...
The Task Manager will show if it's still doing its stuff...
