Hi Stan, would you mind to post such threads in developers section of the forum? Usually the newbie section is about SU's usage.
Thanks.
hi massimo,
sorry, of course, didn't think about that , i'll be carefull in the future!
stan
hi tig,
sorry, is this
"As I said before... please put extracts of code in a 'code' BBCs tag [][/], shorter bits can be unformatted in a 'ruby' tag [][/]"
ment for the forum syntax? if so, is there a guide? please excuse, when i missed it so far.
for the ruby:
what ever i do, i cannot manage it within the loop (weven hith your tips). placing one element after each other works perfect. so i have to go a step back and need some days to study the basic principles of variables and instances (but the ruby grows!!!).
thanx a lot , i keep on trying...
stan
hi,
i just studied the different variables (@, $), but i cannot find out, why my definition does not work:
i define certain variables in loop 1:
for pfosten in 0..2
pfostenname=[]
pfostenname[0] = "masterpfostenl"
pfostenname[1] = "masterpfostenr"
pfostenname[2] = "mittelpfostenm"
..........
else
.........
end
puts "creating component"
puts pfostenname[pfosten]
pfostenname[pfosten] = group.to_component
end
after this, the 3 components are created (master elements for further transformation). OK
BUT
in the following loop (later in the ruby)
if (step) / il == podestnr #some conditions
componentinstance =
entities.add_instance(masterpfostenl.definition, pf1p) # copy to point pf1p
elsif
..................
elsif
....................
end
the add instance function reports:
Error: #<NameError: undefined local variable or method `masterpfostenl' for main:Object>
why does this happen?
the component with the name "masterpfostenl" exists and is placed on the screen
so why does the transfer-function not find it?
thank you a lot. i just ry to understand, how the variable-instances work...
stan
hi tig,
ok, you are right, puts does it automatically.
the declaration of the variables happens in the beginning of the ruby,
first loaded from the default file and then possibly changed by the user...
these settings then create the geometry and are saved to a separate file (later as function : reload last user parameters).
will just try the puts-version.
stan
EDIT: IT WORKS
parameters are saved at the end of ruby
and
automatically reloaded on start
wonderful!
hi,
with this code i can save a row of my variables to a text - file, but in one line
file = File.open("C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/zf/partemp.txt", "w") { |f|
f << lines[0].to_f
f << lines[1].to_f
f << lines[2].to_f
}
when i try to separate the values by \n, there is a syntax error:
file = File.open("C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/zf/partemp.txt", "w") { |f|
f << lines[0].to_f\n
f << lines[1].to_f\n
f << lines[2].to_f\n
}
no tips about this on the net.
any tips for the syntax?
thanx stan
hi dan & tig,
thanx a lot, though this is a different approach than mine, but very useful. i will try to implement thiscurslr functionality , too, if i manage it.
for my idea i will let the user draw 1 line, which can maybe be selected for the ruby call and give the ruby the vector to transform the object.
so the ruby-fight continues...
stan
YEAP!
smooth like a sup of tea with milk on a sunny afternon......
smoothing works perfect , thanx a lot ("again what learned", as we say here in bavaria)
lost a ot of time today with fighting again coordinate systems, whatever i do, the elements don't place themselves sometimes , where i expect them to, it seems, that within groups and components the time & space works different sometimes.....
stan
hello,
this piece of code is very helpful.
in my case this works:
model=Sketchup.active_model
ss=group20.entities
edges=[]
ss.to_a.each{|e|
edges << e if e.class==Sketchup::Edge
e.entities.each{|ee|edges << ee if e.class==Sketchup::Edge}if e.class==Sketchup::Group
}
edges.each{|edge|
if edge.faces[1]
edge.soft=true
edge.smooth=true
end
}
BUT THIS ONE (smoothing with angle limit)
model=Sketchup.active_model
ss=group20.entities
edges=[]
ss.to_a.each{|e|
edges << e if e.class==Sketchup::Edge
e.entities.each{|ee|edges << ee if ee.class==Sketchup::Edge}if e.class==Sketchup::Group
}
edges.each{|edge|
ang=edge.faces[0].normal.angle_between(edge.faces[1].normal)
if edge.faces[1]
edge.soft=true if ang < 45.degrees
edge.smooth=true if ang < 45.degrees
end
}
is quit by following:
VAR. 0.1 k
load '01.rb'
Error: #<NoMethodError: undefined method normal' for nil:NilClass> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:1516:in draw_stairs'

C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:973:in `each'
any idea about the "normal" problem?
thanx stan
hi tig,
exactly that is my problem.
if i was defining the position for the object placement myself, i of course could transformate myself to a desired x,y,z-position.
but
what do i do, when the desired x,y,z is defined by the user (set coordinates axis) before he starts the script?
so the question is, is it possible to 'read' the user-defined axis-offset from some global variable?
stan
hi tig,
the situation is the following.
when i calculate coordinates for the parts of my geometry to be created by the ruby, i have all measures related to 0,0,0.
but this is always the global zero.
what i would like to achieve is, that the user sets the axis at the point, where the new geometry is to be generated, with x-axis defining the orientation (the ruby would only take the temporary 0,0,0 , the direction of the horizontal compoment of the x-axis and place the object - always horizontal at X).
so if there are global variables showing the offset from global zero to temp-zero, i could place the object at global 0
and transform it (move).
stan
hello gentlemen,
now the question is:
how can i place my own object per ruby on
user defined coordinates (means: where the user definies per axis-position)
so the object's X-coordinate would be the AXIS's X and the 0,0,0 of the object
would be 0,0,0 of the USER's axis (temp.)
i cannot find anything about axis-positioning in the api....
thanx & regards stan
thanx stan
hi tig,
that's it .
my logic was ok, your tip for the conversion of string to float was the point.
basicly it works like this:
i have menues for parameters
then the geometry is created
before the end of the ruby i save all parameters to a text file (by the way still looking for the syntax to save more of them line by line)
then the user can recall the ruby and select
-my last parameters
-defaults
and so on and so on
again another step!!!!
regards stan ( i'll report , when i get further)
hi tig,
you are the greatest, as always.
it works.
it's funny, that "my" wrong syntax works at the beginning of the ruby...god knows....will correct all of them.
again a step nearer to my first ruby (for everyone then, of course)
regards and thax
stan
hi,
with this code (the FAKTOR is only fpr inch/cm recaltulation )
model = Sketchup.active_model
entities = model.active_entities
rl1 = [-50/faktor/100,0/faktor/100,20/faktor/100]
rl2 = [-50/faktor/100,10/faktor/100,30/faktor/100]
group40 = entities.add_group
entities2 = group40.entities
new_line = entities2.add_line rl1, rl2
length = new_line.length
centerpoint = rl2
# Create a circle perpendicular to the normal or Z axis
vector = rl1
vector2 = vector.normalize!
edges = entities2.add_circle centerpoint, vector2, 3
kreis = entities2.add_face edges
kreis.pushpull length
i normally (and even in the beginning of this ruby-script (other cylinder)
can pushpull along the line without any problem.
BUT
at the end of the script the same code lets the circle turn to an undefined angle.
absolutely crazy.
any idea how to fix it? >> screenshot
thanx.
stan
hi tig,
thanx a lot, i inserted the new import routine and tried different variantion.
ruby gives back:
load '01.rb'
true
Error: #<NameError: undefined local variable or method lines' for #<Object:0x3d31654 @v_b="90", @v_a="300", @v_c="100">> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:96:in draw_stairs'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:48
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:96:in call' C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:96 load '01.rb' true Error: #<NoMethodError: undefined method /' for "300":String>

C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:96
so the situation is:
i am created an object in skp, which can be controlled in diverse dimension by an input menue (parameters)
when the object is created, i save the parameters in a text file (parttemp2.txt):
content of parttemp2.txt now for testing:
300
90
100
it seems, that reloading these numbers gives back STRINGS and not numbers
as <ou also said, i would like to handle these imported parameters by
parameter01 = lines[0]
parameter02 = lines[1]
and so on.
but it simply does not work now for me. have to study more about formats (you know, i am on ruby since few days)
this is the whole pert of the code: (where WIDTH shall become the value of line 0 in the text-file)
require 'sketchup.rb'
#require 'offset.rb'
#require 'makesoftsmooth.rb'
.
Sketchup.send_action "showRubyPanel:"
#Add a menu item to launch our plugin.
UI.menu("PlugIns").add_item("01-ZF-Stairs"){
UI.messagebox("Outdoor-Stairs - Script - 131011-V 0.1j - Zdenek Fajfrlik")
#result = UI.messagebox "New Definition?", MB_YESNO
#if result == 6 # Yes
#count = 0
#File.open('C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/zf/partemp.txt', 'r') do |f1|
#while line = f1.gets
#puts line
#width = f1.gets
#end
#end
file = 'C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/zf/partemp2.txt'
lines=[]
IO.readlines(file).each{|line|
line.chomp! ### removes the '\n' from the end of the line
next if line.empty? ### this traps for empty lines
lines << line
}
v='@v_a'
lines.each{|e|

hi tig and hello again,
this is great and worked inmedialtely in the ruby console.
so:
i counts the lines
line gets the value per line
maybe a small tip (i still think too much in macro-basic)
when i retrieve those values form the file,
this syntax makes problems:
a = line[1]
b = line[2]
c = line[3]
how could i build an array within the import routine? i tried so many ways and can#t get it...
thanx stan
hi,
when i reopen my text-file with parameters (1 parameter per line)
by
count = 0
File.open('C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/zf/partemp2.txt', 'r') do |f1|
while line = f1.gets
puts line
end
end
i can see the values listed in the console // OK
BUT
when i try
count = 0
File.open('C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/zf/partemp2.txt', 'r') do |f1|
while line = f1.gets
puts line
value[count]=f1.gets
count = count + 1
end
end
it does not work
ma question is:
how can i assign the result of f1.gets to a row of variables in this loop?
thanx you
stan
yes sir,
it works perfectly. so this deletes the master-component.
i just wonder, how then can be identified the ,daughter'-components.
per x,y,z ?
anyway, thank you very much for this solution.
stan
hi tig,
probably i have a mistake in the component-description.
i define a master component (two tubes).
#DEF PFOSTEN MASTER COMPONENT
model = Sketchup.active_model
entities = model.active_entities
pfm1 = [0, 0, 0+thickness]
pfm2 = [0, 0, 0+thickness+sl-((5/faktor)/100)]
pfm3 = [0, 0, 0+thickness+sl-((5/faktor)/100)]
pfm4 = [0, 0, 0+thickness+sl]
group = entities.add_group
entities2 = group.entities
new_line = entities2.add_line pfm1, pfm2
length = new_line.length
centerpoint = pfm1
vector = pfm2
vector = vector.normalize!
edges = entities2.add_circle centerpoint, vector, pradius
kreis = entities2.add_face edges
kreis.pushpull length
new_line2 = entities2.add_line pfm3, pfm4
length2 = new_line2.length
centerpoint2 = pfm4
vector2 = pfm3
vector2 = vector.normalize!
edges2 = entities2.add_circle centerpoint2, vector2, pradius/3
kreis2 = entities2.add_face edges2
kreis2.pushpull -length2
masterpfostenl = group.to_component
and then copy it to different places to ponits pf1,2,3:
componentinstance =
entities.add_instance(masterpfostenl.definition, pf1)
componentinstance =
entities.add_instance(masterpfostenr.definition, pf3)
componentinstance =
entities.add_instance(mittelpfostenm.definition, pf5)
after all components are placed, i will try the
defn.instances.first.erase! (have still to find out, how to point the right "instances-group"
thanx
stan
[quote="thomthom"]To delete one entity: use Entity.erase!
entity = Sketchup.active_model.active_entities[0] entity.erase!
hi tig,
in my first ruby i have already managed it to copy one master-component (created with ruby at [0,0,0] and copying it, where ever i want.
after placing it in all places wanted, i would like
to DELETE this particular master-component.
i found your code:
entity = Sketchup.active_model.active_entities[0]
entity.erase!
but how can i define , which component is to be deleted? is there a name somewhere? or index, i could "memorize" while creating the master component? is the [0] maybe a place for a definition?
thanx a lot for helping!
