J'ai mis une nouvelle version dans la partie Ruby Discussions
http://www.sketchucation.com/forums/scf/viewtopic.php?f=153&t=6708

Cette version est plus interactive et fournit un feedback visuel de la deformation.

Et il y a un bouton Redo pour Pilou

This is a resurrection of the OLD version of the plugin, published in 2008 and last updated in 2011. It works in all versions of SketchUp and is certified for SU2016 and SU2017. It does NOT require LibFredo6.

Note: There is a new version of JointPushPull, called JointPushPull Interactive Edition 3.0. It includes new extrusion tools and is more interactive.
So you should consider migrating to this new version.
See this post.

Here is the link to the starting post of this new resurrected plugin.

JointPushPull Classic is a script that performs push pull on multiple faces in one operation. Unlike the native Sketchup push-pull tool, JPP Classic can maintain the continuity of the offset surfaces (mode joint push pull). This is useful to thicken non-planar surfaces.
JPP also includes two additional modes: Vector and Normal working with multiple faces.

[attachment=0:3upnsc38]<!-- ia0 -->Tutorial Joint Push Pull Classic - English - v1.1 - 20 Feb 08.pdf<!-- ia0 -->[/attachment:3upnsc38]

• Language: English, French, Spanish (Defisto), Italian (Defisto / COSEDIMARCO)
• Menus: by default, it is installed in Tools > Join Push Pull. There is also a Joint Push Pull menu in the selection contextual menu when one or several faces are selected
• Icon toolbar: Joint Push Pull (5 icons are available)
• The plugin is free, for private and commercial usage.

Although the plugin is obsolete now, this old version is published on the Sketchucation PluginStore under the name JointPushPull Classic.

IMPORTANT: This version can co-exist with the NEW version JointPushPull Interactive.

It is advised to

• install the rbz extension from the Sketchucation PluginStore page for JointPushPull Classic
• or Auto-install JointPushPull Classic with the ExtensionStore plugin distributed by Sketchucation

The footprint in the SU Plugins Directory must be:

• Fredo6_JointPushPullClassic.rb file
• Fredo6_JointPushPullClassic folder

In case you had the old JoinPushPull v2.1 already installed on your computer, it is advised to remove:

• the folder JPP_Dir_21
• the file jointpushpull.rb
• the file LibTraductor.rb

CAUTION: NEVER rename or move files from their folders. If you are unsure of your unzip operation, do it in a neutral folder and check that you reconstruct the right footprint. Then transfer the folders and files to the SU Plugin Directory.

• Select one or several objects (faces, edges, groups or components). Only faces are taken into account.
• Click on the icon of one tool, for instance Joint Push Pull
• Pick a face and gently move the mouse to visualize the offset in wireframe. Keep SHIFT pressed to skip inferencing
• You can type the offset value in the VCB (in model units)
• Type TAB to access options (thickening, continuity parameter, etc…)
• When OK with the parameters, Double-click or press Return to launch the calculation
• The calculation cannot be interrupted. On large models, you may thus get a blank screen for the time the script is computing. Do not panic, just wait, it may take several minutes!

JPP also includes 2 additional buttons:

• Undo - reselect faces (as precisely the original faces could have been erased)
• Redo last Push Pull, allowing executing the last push pull on a new set of faces, with the same parameters.

version 2.2a - 26 Apr 17: same as version 2.1a but certified for all SU version, including SU2017. Published on PluginStore as JointPushPull Classic

version 2.0b - 17 Jul 11: same as version 2.0a but with Italian translation. This version does not work beyond SU13.
Here is the file, just in case

See [url=http:http://forums.sketchucation.com/viewtopic.php?f=323&t=6708&p=342359#p342359]http:http:http:http:http:http:http:http:http:http:http:http:http:http:this illustration[/url].

version 2.0a - 16 Jul 11: refix a bug signaled by Thomthom for some complex shapes (typically with vertices having 5 edges or more). Version 1.9 had some problems left.

version 1.9a - 12 Jul 11: fix a bug signaled by Thomthom for some complex shapes (typically with vertices having 5 edges or more).

version 1.8a - 01 May 11: Better respect of specified distance now working when doing a Joint Push Pull with an imposed plane direction. See discussion in [url=http:http://forums.sketchucation.com/viewtopic.php?f=15&t=36403&view=unread#p325069]http:http:http:http:http:http:http:http:http:http:http:http:http:http:this thread[/url].
Here is the previous version, just in case

version 1.7a - 25 Apr 11: Fix a major bug (causing a freeze of SU in some situations).

version 1.6 - 22 Apr 11: Updated the algorithm to better respect the value of the offset when the surface is composed of sharp angles. THIS VERSION HAD A FREEZE PROBLEM.

version 1.5 - 02 Sep 10: maintenance release for SU8

• Suppress some warning (though harmless) messages in the Ruby console
• JPP now installs itself as an extension of Sketchup (can be disabled / enabled via the Windows > Preferences > Extension dialog
• Spanish translation - Thanks to Defisto

12 Jun 10: stable version, with encapsulation of calculation to skip some known problems on texturing.

Tutorial Joint Push Pull - English - v1.1 - 20 Feb 08.pdf

@al hart said:

1. If you examine the .SKM file, you will discover that it is a zip file with the material stored in it. So if you have a way to read the zip file from Ruby, you can access it.

This is good to know, but it would be rather convoluted, especially for the objective I research which is just a script to put the selection in Xray, while the rest of the model is unchanged.

@al hart said:

2. Another way we get the texture is to assign the material to a face or image and use TextureWriter to write the textures to a file. (If it is a "distorted" texture, it will not write the original texture, but rather the texture as it appears on the face.)

I played with the Texturewriter of course, with a Load from a face, but the method filenamedoes not even return anything!

Actually, the question is not really to get the texture, but to create a material as a clone of another one, and then change some parameters(in my case the transparency via the Alpha method). You can do all this with the User Interface of the Sketchup paint bucket, but apparently the Ruby API is far behind.

Thanks for your help.

Is this possible?
I did not find anything in the Ruby doc about how to do that.

What I have found is that:

• You can create a new material by name
• you can only assign a texture to the material by filename (it has to be a JPG)
• However, with SU v6, the JPG is not available as a file but embedded is the SKM file of the material

Thanks

Fredo

Wireframe is even simpler, as you just hide / show the faces

The big problem for Xray, is that I don't find any way to create a material from an existing one, or to assign the new one the same texture as the old one, especially with SU v6, as the JPG are now embedded in SKM files. So the macro works without texture at the moment.

Does anyone see a solution?

J'ai simplement oublié d'attacher l'icone

@unknownuser said:

tu parles d'un "X" coloré? où c'est qu'il est celui-là

C'est un bouton dans la toolbar (verifie que cette toolbar est bien affichee).

@unknownuser said:

Les textures disparaissent complètement? C'est normal parce que le % est trop grand ou par ce que n'est pas géré par le script?

Petit probleme dans Ruby. Pas moyen d'avoir le path complet de la texture. Il y a un bug dans l'API.

@unknownuser said:

Ps Pas moyen d'avoir un % réglable?

Ca c'est plus facile. J'avais choisi 0.25, mais il me semble que 0.35 est plus fidele a un Xray.

I quickly built a script to toggle Xray on a part of the model and posted it in the French section of the forum (at http://www.sketchucation.com/forums/scf/viewtopic.php?f=51&t=6589&st=0&sk=t&sd=a&start=30

As Todd says, it will double the number of materials, as you have to duplicate materials present on original faces with an alpha transparency set to 0.25. So "purge unused" should be done at some point. It may also take some time on large models.

The script works on a selection of groups, components or isolated faces, possibly nested.

It will Xray the selection. Then, if you do not select anything, it will work in Toggle mode (Xray / Normal / Xray / Normal, ...)

XraySelection.rb

Claire,

On peut simuler le Xray par un petit script qui fonctionne comme suit:

1. Tu selectionnes la partie du modele que tu veux rendre en XRAY. Ce peut etre un ou plusieurs composants ou groupes, meme emboités ou des faces isolées.

2. Tu appelles la commande Xray selection(ou cliques sur le 'joli' icone en forme de X coloré). Cela transforme la selection en Xray

3. A partir de la, la commande marche en mode bascule si tu ne fais aucune selection (et a condition de ne pas effacer ou rajouter des faces dans la partie concernée du modele).

• Donc si tu recliques, la partie en Xray revient en mode normal
• Si tu cliques de nouveau, elle passe en Xray

4. Si tu refais une sélection, tu te retrouves en fait a l'étape 1

Le script est attaché.

Remarque: en Ruby, il faut creer des nouveaux materiels (en mode Xray). Donc n'oublie pas de faire un "purge usused" de temps en temps (tous les materiels creés se termine par "___XR". De meme, si tu as fait des positionnements fins de texture, tu ne les retrouveras pas (je peux se faire en Ruby toutefois, mais c'est un peu plus long).

Voila. Bon courage et dis moi si c'est utile.

Fredo

A mettre dans le dossier "plugins"

Here is a very first version of what I call Joint Push Pull, which is a compromise between the classic Sketchup push pull along individual face normals and the Vector Push pull whihc keeps faces contiguous. In other terms, how to extrude faces along their normal, but generate a contiguous shape.

I guess the pictures attached are self-explanatory on what the script tries to achieve.

The ZIP archive should be unzipped in the Plugins folder and create in the Plugins folder:

• jointpushpull.rb, the main macro
• LibPlaneSelectorTool.rb, to select a custom plane
• LibVectorSelectorTool.rb, to select a custom vector
• LibTraductor.rb, for language translation and dialog boxes. This is a new version (you must use this one, but it is compatible with the previous version published with Bezierspline)
• LibTraductor.def, an optional configuration file allowing override of language
• A folder JPP_Dir, which contains the 2 icons for the toolbar
  The script creates 2 menu entries in the Tools menu
  The script also implements Classic Push Pull and Vector Push pull

There is a full doc in PDF, but it is too large to upload on this site. So I put it on the Google forum at http://groups.google.com/group/Ruby-API/browse_thread/thread/6ae80c5c688083fb.

JointPushPull.zip

I guess the whole point is to understand whether there is a way to know 'in advance' the size of a text (based on string and font) so that it can be positioned accurately in the model at creation.

On my side I did not find a way to do that.

Thanks very much.
I know how to do it via Windows, but if we start programming in Windows SDK instead of Ruby, this is less fun, and more important, additional headaches for deployment.

One suggestion would be a few members of the sites, knowledgeable in system programming (Windows and Mac) group their efforts to build a utility libraries (dll) to complement the Ruby API of Sketchup (menu, events in tools, mouse, etc...). Unless the Sketchup SDK is more powerful!

I was wondering if there is a way to move programmatically the mouse pointer, within a Tool.
This may be useful when you have to open a dialog box and want to reposition the mouse pointer where it was before.

Thanks in advance for your help

It seems that at least you triangulate the faces, from what I could judge with the deer's kees (and the few faces that were not triangular in the original model).
This is a great tool, and judging from the video, the performance are more than "better"! (compared for instance to a simple shear of the model, that would take 40 seconds with a Ruby script). I imagine that you use a compiled version in C++).
I would encourage you to continue on this path, really!
If you need some help for the GUI, just post a description of what you need and I am sure we would find a way to contribute.

I have this one in preparation, for a composite model (i.e. any drawing elements, groups, etc... with texture transfer, etc...) and a curve in 3D space.
Actually, the main difficulty is about managing some topological cases where it is necessary to remove and cut faces that are squizzed in the curvature.

Looks like it does not find the cursor PNG file (cursorshear.png)
It must be in the Plugins directory
I thought I had put some code to check in any case, but apparently this does not work.

Mais c'est bestial comme truc!

Ne serait-il point possible de répéter les dernières entrées paramétrables (celles-ci étant satisfaisantes d'une précédente action) sans passer par l'ouverture du Menu et l'appui de la touche "OK"?

Par un simple clic droit sur l'icône par exemple?
Mais c'est pour finasser sur l'ergonomie et booster la vitesse de modélisation
On doit gagner une seconde peut-être deux

Merci pour l'appreciation. J'espere que cela rendra quelques services.

Je me suis poser la question d'une execution 'rapide', mais on tombe rapidement dans l'indecidable car il y a pas mal de parametres. Sketchup ne permet pas de capturer un clic droit sur l'icone, et en creer un autre conduit a une proliferation des icones deja fort nombreux. En fait, je pense que quand on travaille sur un modele serieusement, on n'utilisera cette operation que rarement, et avec une preparation qui fait que quelques secondes de plus ou de moins ne changeront pas grand chose.

Azuby,

In theory, we could imagine that a user would not call a PDF at each Skecthup session, and if he does, after all, he could wait a little bit.
But your macro is fast enough that this fine too. When we have hundreds of PDF and HTML documenting scripts, we could revisit the problem

All this proves that we have a damned good team of Ruby script programmers on this forum, as it took less than 24 hours to get 3 good versions after the idea just popped up.

This is a great idea and can be done with no major issue (the center of the circle is at the crossing of parallels of segments, at a distance equal to the specified radius). There are of course some tricky cases where the specified radius would be too big and would overlap more that 2 segments, but this can be adjusted.

Great script!
And works fine for me on v6
I gave me some inspiration about what you can do with Sketchup and Ruby, when I redesigned the Bezier curves from the @Last version.

Thanks again

Fredo
