[Plugin] ReGlue

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?

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.

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?

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...

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!
