[Plugin] ReGlue

TIG

Here's a new future-proofed update.

TommyK

There are times when I would like to select several components and reglue them to a face with one "ReGlue" operation. I have modified TIG's code a little to allow multiple selections of components. Hope you don't mind, TIG. The code is below, and not tested that much....

nice little gem TIG. Saves a lot of repetitive stupid work.

Just as TommyK I changed it to a multiple reglue by
comps.each{|c|c.glued_to = face}
and uncommenting the
#return self.error("ReGlue:\nSelection MUST contain ONE Component !") if comps.length==0 || comps[1] #comp=comps[0] #comp.glued_to = face

JQL

I also feel the need to have multiple components reglued. I'm used to using Superglue for that but Tig's Reglue works much better.

So, Tig, are you thinking of adapting your own script to any of the above methods?

If not, I think I'll use Tommy's from now on...

Thank you guys!

TIG, Is it possible to enable multiple components (implemented above by TommyK) re-glueing to multiple faces please?

TIG

An instance can only glue to one face.
It's a limitation within SketchUp, not the API.

rv1974

Does this API the Great and Powerful, allows to select all the components glued to a preselected face? If yes, maybe the script could take one face, select all the glued and reglue; then go to another face, repeat reglueing, and so on?

Pixero

Maybe Fredotools Move along could be helpful?

ToomyK's version a few posts back does that.
Just replace the text in the RB file with his alternative and save it.
Use a plain-text editor like Notepad++ to do the editing.

TIG

How is the code to determine which of the selected components gets glued to which selected face ?
Please outline the 'logic'...

No, TommyK's code works only with one face.
@Pixero, the connection between MoveAlong and reglueing slips away from me.

Thats what I tried to ask you earlier- Whether API allows to detect the components glued to a preselected face. IF the answer is YES, then MAYBE the script could(?) progressevly take face by face and reglue corresponding components.

I did this but it’s small script. Select face and components for reglue.

and components? or face only?

TIG

There is a method:
glued = face.get_glued_instances
And it'd be easy to grep then iterate all of the faces and their glued components etc...
BUT there's no API ' .could_be_glued_instances' method...

BUT here's some possible [pretty much untested] code which might just do it...


ctr=0
model=Sketchup.active_model
faces=model.active_entities.grep(Sketchup;;Face)
comps=model.active_entities.grep(Sketchup;;ComponentInstance).find_all{|e|
  e.definition.behavior.is2d? && ! e.glued_to
}
### collect if comp can glue, but not glued !
cct=comps.length
faces.each{|f|
  plane=f.plane
  norm =f.normal
  comps.dup.each{|e|
    pt=e.transformation.origin
    nm=e.transformation.zaxis
    if pt.distance_to_plane(plane)==0 && norm==nm
      ### glue-able
      cp=f.classify_point(pt)
      if cp==Sketchup;;Face;;PointInside || cp==Sketchup;;Face;;PointOnEdge || cp==Sketchup;;Face;;PointOnVertex
        ### on face so can glue
        e.glued_to=f
        comps.delete(e)
        ctr+=1
        ### reduce tested comps collection for speed
      end
    end
  }
}
puts "\n\nReglued #{ctr} of #{cct}" ### print how many reglued

@TIG This plugin reglues multiple components in SU 2022. In v2023 and newer it reglues only one component.
What is the reason for this degradation? Thanks

This plugin is over a decade old !
As far as I recall, and tell from the code and version, it has always needed a selection of one face and one component to work. for 19 years.
Although I do see from my posts do speaks of one or more components being processed...

As far as I can see this old code is very simplistic... e.g.

It does not check for gluing properties, or face-normal, or Z-axis, or position on the face.plane, or transformation.origin point on the face at all.

If it checked for several components being on the face and sharing the face.normal as their Z-axis etc, then it would be possible the get it to process several gluing components. However, this would require a complete rewrite...

I'll back check...

TIG

Here's v2.0 in the PluginStore...
https://sketchucation.com/pluginstore?pln=Re_Glue
It now allows multiple pre selected component-instances, but still only one preselected face.
These are glued to the face [is possible], any errors or unsuitable instances are reported in the Ruby Console...

@TIG Many thanks!
