RE: [Plugin] Import ALL from Folder
TIG,
Do you know of any .stl batch importers? I have found two .stl importers but nothing with the batch capabilities.

RE: Intersecting Hollow Objects using intersect_with
Well I've been using the "solid" tools for the last few days and it is a whole lot easier than what I was trying before. It would be nice to find a non-Pro version, for home use. The following is my test_code. I will re-write using Dan's previous post as a guide. It's a little over my head at this moment and I'm still trying to completly understand it.

RE: Intersecting Hollow Objects using intersect_with
Thanks TIG. I am still working on this and will post my results.
On a side note:
I tried to create a function in the module I wrapped everything in and it won't load in Sketchup but works fine outside of the function block.
ex.module PMA_INT_TEST ..code here to create geometry end #of moduleload PMA_INT_TEST.rb into Sketchup works fine
then I changed:
module PMA_INT_TEST create_geometry() def create_geometry() exact same..code here to create geometry end end #of moduleload PMA_INT_TEST.rb into Sketchup get:
Error: #<NoMethodError: undefined method `create_geometry' for PMA_INT_TEST:Module> -

@dan rathbun said:
But of course the coding means is not documented because the Free license users are not supposed to do it. (... or at least use a wizard interface.)
That's a bummer. I like the concept of dynamic tools for locking up variables and documenting the components, but I hate the user interface! It would just take me too long through traditional means to create a workable library. And of course if I wanted to change something I would have to do it in multiple places. I will do a more active search for creating/modifying dynamic components through Ruby. So far what I have found has not been that helpful besides holding/setting attributes. Any tips on where to start?
Thanks! -
RE: Intersecting Hollow Objects using intersect_with
Thanks for the plugins, TIG! Those are awesome starting points for me. I will need to modify them so that they work for any plane that is non-orthogonal to the orgin. But I think that's just a matter of creating a "plane" through code and not choosing it like the plugin. Thanks again!

RE: Intersecting Hollow Objects using intersect_with
Thanks TIG,
I will definitely give that a go. I'll have to start up my work computer to give it a try though. I use the "free" version on a mac at home and the Pro windows version on my work laptop.Dan your thoughts are exactly where I wanted to go with being able to pick a direction for the cut. I envisioned a future user prompt to pick a side. I still think I could make it look like a plane being cut using TIG's described method by creating the geometry after the pick. But as a tool it would only be usable on a Pro machine it sounds.
I thought using the array comparisons would be a quick check of the entities created, but actually it didn't work out well because it looks as though Sketchup "redraws" entities like lines and faces when the intersect_with happens even if it's basically the same location. That's why I started down the checking edges, then checking vertices, etc.

Intersecting Hollow Objects using intersect_with
So I am attempting to use planes to cut a hollow object. I am having trouble with the weird conditions such as:
Plane cutting a line in the object
The array comparisons don't seem to work on faces and entities reliably? any thoughts?
I did some Array math to help myself out but I think I'm confusing how Sketchup creates entities.array1 = [1,2,3,4,5] array2 = [1,3,5,6] array3 = array1 | array2 array4 = array1 & array2 array5 = array1 - array2 array6 = array1 + array2 array7 = array2 | array1 array8 = array2 & array1 array9 = array2 - array1 array10 = array2 + array1 array11 = (array1 | array2) - (array1 & array2) puts "array1 = " + array1.to_s puts "array2 = " +array2.to_s puts "UNION 1&2 = " +array3.to_s puts "INT 1&2 = " +array4.to_s puts "Diff 1-2 = " +array5.to_s puts "Add 1+2 = " +array6.to_s puts "UNION 2&1 = " +array7.to_s puts "INT 2&1 = " +array8.to_s puts "Diff 2-1 = " +array9.to_s puts "Add 2+1 = " +array10.to_s puts "UN 1-2 - int 1-2 = " +array11.to_s =begin ARRAY MATH EXAMPLE array1 = 12345 array2 = 1356 UNION 1&2 = 123456 same but order changed UNION 2&1 = 135624 INT 1&2 = 135 and INT 2&1 are SAME!

RE: Help Understanding Classes and Class objects
I will check into the mixin module approach also the dynamic components. Are dynamic components "create-able" through Ruby code or only through the Sketchup interface?

RE: Help Understanding Classes and Class objects
Dan you are correct. Adding the .group gave me access to the "group" objects that were created.
As for my thought process I am not sure that it is valid so let me describe my thoughts.
I don't want to code "like" things so I assumed that using classes would allow me to inherit class attributes things without having to copy a bunch of code it multiple places. For example classes would be:
- FUNCTIONAL AREAS
[list:11tc2ay1]1. CONVEYOR
-
CONVEYOR_COMPONENTS
-
END_PULLEY
-
DRIVE
-
INTERMEDIATE_BED
-
PAN_GUARD
-
BEARINGS
-
ETC.
-
BUILDING_MODSETC.[/*
11tc2ay1][/list
11tc2ay1]Later I could write Customer specific code for each of the classes and inherit all of the functionality that I wrote in the "General" Classes
One customer's end_pulley may contain different bearings, pulleys, profiles etc. Also there are many types of end pulleys. That being said they do have some similarities especially attribute definitions, layer structure, basic functionality.
Am I on the right track or am I way off the rails?
- FUNCTIONAL AREAS

RE: Help Understanding Classes and Class objects
So I added the return @group per your recommendation TIG however I am having some confusion as to how Sketchup sees the newly created groups. It doesn't seem like you can manipulate the returned groups as per the example code below returns undefined method transform!
It seems as though Sketchup is treating the groups st_ep and end_ep as objects not groups. I have been creating "dummy-container groups to bypass this like Conveyor but I'm guessing from your comment there is an easier way to access the groups that I am creating in the EndPulley class?module CONVEYOR #CONVEYOR.rb # Type in Console # load 'Conveyor/CONVEYOR2.rb' # ex. conv = CONVEYOR;;Conveyor.new([0,0,0], [0,120,0]) require 'sketchup.rb' class Conveyor #make the @group var and .group()instance attr_reader(;group) #private #why does this need to be private? def initialize(st_point, end_point) ents = Sketchup.active_model.entities #t1 = Geom;;Transformation.translation [0,0,-5] @st_point = st_point @end_point = end_point #hold reference to group; @group = ents.add_group() cpt = @group.entities.add_cpoint(ORIGIN) @group.name = "CONVEYOR ASSY" #@group.transform! t1 self.create_geometry cpt.erase! end #of initialize() def create_geometry() ents = Sketchup.active_model.entities t1 = Geom;;Transformation.translation [0,0,-5] #pulley 1 st_ep = EndPulley.new(@group, @st_point) #puts st_ep st_ep.transform! t1 #pulley 2 end_ep = EndPulley.new(@group, @end_point) end_ep.transform! t1 end #of create_geometry() end #of Conveyor class class EndPulley attr_reader(;group) def initialize(conv_group, ins_pt) #TODO; add *args if a group not passed to EndPulley just "create_geometry" @conv_group = conv_group @ins_pt = ins_pt self.create_geometry end #of initialize() def create_geometry() pts = @ins_pt width = 36 length = 18 ents = Sketchup.active_model.entities pt1 =[pts[0] - (width/2),pts[1],pts[2]] pt2 =[pts[0] - (width/2),pts[1]+length,pts[2]] pt3 =[pts[0] + (width/2),pts[1]+length,pts[2]] pt4 =[pts[0] + (width/2),pts[1],pts[2]] @group = @conv_group.entities.add_group() face = @group.entities.add_face pt1,pt2,pt3,pt4 face.reverse! face.pushpull 5 @group.name = "END PULLEY" return @group end #of create_geometry() end #of EndPulley class end #of module CONVEYOR -
RE: Help Understanding Classes and Class objects
I'm not sure if my last post went through. I wanted to thank everyone though. Also I got everything working and kept the two classes seperate for future inheritence. I had to remove the "private" so that the methods for the Conveyor class could be accessed. I'm not really sure why?

RE: Help Understanding Classes and Class objects
First of all I would like to thank you guys for all of the help. My thought process was skewed in the wrong direction and I don't think I would've come up with the passing the group object. Also starting with the group and then adding the entities is now clear in my head. I had read that before in other posts but could never quite understand the "how". That was where I was hopelessly stuck for the past day. I have re-written the previous code and module-ized it and it works perfectly.
I kept the classes for Conveyor and EndPulley seperate so that I can use both seperately for inheritance in the future.
I still need to check into "Wrapper" classes further for how I can implement them effectively.
The only snag was I had to remove the private designation for the methods under the Conveyor class to work. I'm not really certain why.
