I tried by change name of load_plugin.rb to z_load_plugin.rb but it seems not solve my problem

The program I used as a model when starting used that method. However as I added more functions it became almost impossible to find how to get out to the end of the mouse click down def.

More Specifically: Would the Range.Find method help?

I am using an If else statement, I got it to work earlier in the code, but now I am having an issue grouping a new entity and finding it's face, it has to do with adding an arc and not adding an arc.

It seems to me that you define 'edg' twice if l=="Yes" but don't define it at all if l=='No'.

#ROUND Nose Yes/No<<<<<< if l=="Yes" puts "top hanger round nose" #add arc<<<<<< edg = ent5.add_line [0,b+3,b-c], [0,b+3-0.5,b-c] ;vrt1=edg.end ent5.add_arc [0,b+3-0.5,b-(c/2)],[0,0,b+3-1],[-1,0,0],-c/2.0,0,180.degrees,12 edg = ent5.add_line [0,b+3+h,b], [0,b+2.5,b];vrt2=edg.start #end Add Arc<<<<< else puts "top hanger square nose" edg=ent5.add_line [0,b+3,b-c], [0,b+3-1,b-c]#<<<< edg ent5.add_line [0,b+3-1,b-c], [0,b+3-1,b] ent5.add_line [0,b+3-1,b] , [0,b+3+h,b] end #add the face to the entities in the model edg.find_faces; face=edg.faces[0] face.pushpull wdth

Using the Geom methods, and the methods on Geom::Point3d, Geom::Vector3d as much as possible is beneficial for performance. The SketchUp API methods are implemented in C++ and will be faster than pure Ruby code.

You should have a look at the SketchUp Team's Shapes and Window Maker example extensions. They (and a few others) use a library class called Parametric that handles creating a inputbox of parameters and saves them into an attribute dictionary attached to the (group or component) object.

Why reinvent the wheel?

Well, a start of explaination and solution, here :

Put an observer on edge.start and edge.end

Thanks TT !

Not sure what is available in pure Ruby, but if you create Ruby C Extensions it open up a whole lot more - as you can make use of C/C++ libraries. It's often a lot more libraries available for C/C++ when you want to go beyond the standard Ruby API.

As TIG said, add_line was a deviance from what the norm. I think it got named like that because in the UI you have the "Line Tool". But in the API this is an unfortunate inconsistency.

And as Dan mentioned, please report documentation issues in the GitHub repo.

I queued up some cleanup to the followme method:

I use a mixture of Visual Studio Code/Sublime Text and RubyMine. I use VSCode/Sublime etc for quick scripts and edits. But for larger projects I use RubyMine as the IDE provide better code insight. It's Ruby debugger tools is also very nice - saving you from "puts debugging".

We just uploaded some guide to setting up RubyMine: https://github.com/SketchUp/sketchup-ruby-api-tutorials/wiki/RubyMine%20Overview

Whow! 😄 👍 😎

This seems to work,
Now I just need to take care of the units.
I will post a reply if I get the Script in a usable condition.

It would be nice if You could take a look at it then.

But I don't know when I'll get enough time for this.
Maybe tomorrow, I got 2go and make Dinner, my Girlfriend already has the knife in her hand 😲
and I don't want her to use it on me. 😆

EDIT:
I kept using the initial approach in setting the Lenx to _lenx_formula since
the other way it left me with an unscalable Component, or at best with a scalable component which doesnt show the correct measurements as the corresponding values in the
DC Dialog.
But Hey, Thank You anyway, maybe someone else has use for the Code for another
useful Plugin 😄 👍

If any file is missing at the moment that there is an attempt to 'use' it - e.g. a texture image, a SKM material, or a SKP component - then the process will fail.
However, once a texture image is used for a material for a model's material, or a SKM material is loaded into a model [v2017], or a SKP component is loaded into a model, then that data is bound into the model and its connectivity to the external reference is no longer needed - so if the file is subsequently deleted nothing bad happens.
Unless a user goes into your extension's subfolder and removes [or renames] images, or SKMs or components, before the load attempt, then it will always [re]load.
If you rely on 'shipped Materials', then if they are there they could load [v2017], but of course if they are removed by the user beforehand, it will fail...

Thanks jim!!!

Ill confess that I'm far from using math formulas like that but it gives me a good reference on how it works 😄

I dont know what you're talking about, it looks perfect to me!

Thanks again!

It should if "point" is truly inside the solid. If it is a model point then it will need to be transformed by the inverse of the solid's transformation.

Thanks
Yes the point must be in the solid(group) coordinate space.

I've changed the code a bit to allow shell (outer face) testing
Here it is:

Edited:
After some testing still something was not OK.
I realized that when the ray crosses an edge it hits 2 different planes and through a vertice it can hit an unknown number of faces. The solution I came is that the ray crosses the solid in only one point. So instead of keeping track of how many faces it hits, I register all points the ray hits the solid and then perform a uniq-like operation to the array to count the number of points/hits.
I've updated the code.

For the filtering uniq! doesn't work (guessing because it uses eql? and this is not implemented in Point3d)
Also tried

pts.uniq! {|pt| pt.to_a}

but it didn't worked, but since the raycast is parallel to X axis comparing x coordinate does the trick

def point_insidesolid?(point, solid, exclude_surface=false) vect = Geom;;Vector3d.new(1,0,0) pts = [] solid.entities.grep(Sketchup;;Face).each do |face| if(FaceTools.is_pointof_face?(point,face)) return true unless exclude_surface return false else pt = Geom.intersect_line_plane([point,vect], [face.vertices[0].position, face.normal]) if(!pt.nil?) if(FaceTools.is_pointof_face?(pt,face) && pt.x>point.x) pts.push pt end end end end ptsuniq = pts.uniq {|pt| pt.x} return ptsuniq.count%2!=0 end def point_insideface?(point,face) case(face.classify_point(point)) when Sketchup;;Face;;PointInside, Sketchup;;Face;;PointOnVertex, Sketchup;;Face;;PointOnEdge return true end return false end

Allright, Got it partly working, 😄

But I Cant get the Attribute-Inspectors to show the
Values, I guess I dont really understand how
to set the Formulas correctly to get the corresponding Values by now.

The DC Browser shows the Values (Lengths of the Piece in X,Y and Z)
but everything else does not, this means no reporting so far.

Can anybody push me a little in the right Direction ❓

Where do I have to set the DC Attributes Instance or Definition?
and how could I set it to both if needed?

I tried to set it to the Definition and the second time I run the Script
the created Geometry has no Attributes at all, or at least nothing
important.

The unfinished Script, still buggy

Precision : you have just to rename the .asg in .zip
unzip it
for have a file .xlm

I'm glad it helped.

What I said is true on Windows because there is ever only one Model.

On a Mac you can have more than one model opened. But you still probably need to attach your observers when new models are created.

I have no idea how you determine what @ptw1616 is but another option might be creating an array of the locations like this

All the points are per-determined in my script. They relate to the user selected area.
Various combination of points make a pattern of lights the user can choose from in the Light Array Type Dialog Box.
Your understanding of Ruby has helped me tremendously. Furthermore I did not realize the importance of the last "}" .....which I originally thought might have been a typo........ Yikes!!!

i have to work to understand what you wrote, observers a re new for me

thank you

Taking John's example cross-platform:

❗ This code is fragile, because it deals with someone's else's extension. They could change it (such as method names,) at any time in the future and this example will break.
