hi dan,
super, thanx, i understood and it works now,
besides a small message in the console:
load '01.rb'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:66: warning: already initialized constant THISFILE
true
i start the ruby directly, not in a module (when i put it in the module, it does not work, probably because of all the entities definitions etc. / still workin' on it)
regards stan
post scriptum:
now the transformations of components (turning around z) work,
but i found out, taht the bounding box ( = component internal axes) won't change with the transformation.
i read a lot topics about it, but found no solution.
so, has the api a function to say something like
t = transformation...whatever....component_axes (point, angelx, angle y, angle z) ??
this would be very uswfull to prepare the components for use's edit in right directions!
thanx stan
hi,
with my code i have the following problem:
every time i restart the ruby in the ruby console per
load '01.rb'
the menue entry in the plugins-menue is duplicated (so after 5 calls 5 times the menue, the first one at the top, all the others then call by call at the botton of the plugins menue...))
where is the problem?
Sketchup.send_action "showRubyPanel;"
submenu = UI.menu("Plugins").add_submenu("01-zf-ruby")
submenu.add_item("1 ruby"){
meth_1
meth_2
}
submenu.add_separator
submenu.add_item("2 save last model"){
meth_3
meth_4
}
submenu.add_separator
submenu.add_item("3 load saved model"){
meth_5
meth_6
}
submenu.add_separator
submenu.add_separator
submenu.add_item("4 support"){
UI.messagebox "support" # w.i.p.
}
thanx for checking and helping.

hi icehuli,
that's it! of course, i already had the tanges, so......sometimes it's so clear afterwards...
thanx a lot, the method works now!
new_line = @entities2.add_line @pfm1, @pfm2
@vector = new_line.line[1]
point = [0,0,0]
angle = (Math.atan(var4/@run)).radians
angle = 360 - (Math.atan(var4/@run)).radians if var5 == "right"
tr = Geom;;Transformation.rotation(point,@vector,angle.degrees)
@group.entities.transform_entities(tr, @group.entities.to_a)
stan
hi tig, ok. i will make tests and learn.
but anyway:
why does
angle = Math.tan(20.0/30.0)
give (by puts angle)
0.786842889472977
instead of
0.66666666 (normal tangens)
and if 0.786842889472977 = 20/30 in radians,
why does angle.radians then not give 33.69 degrees?
sorry, i am confused, i seem to misunderstand someting totaly...
stan
hi tig & icehuli,
@tig: yes, the numbers come from another modules and should be float (with direct input "45.degrees" in tr for angle2 the object is turned by 45 degr.)
in the code below i tried the 'simple way', not clear to me, why it still does not work
@icehuli
see the code, the function should be the right one
new_line = @entities2.add_line pfm1, pfm2 # gives vertical line
@vector = new_line.line[1]
point = [0,0,0]
#
angle = (Math.tan(@lwidthplus/@run)) # x,y come from another module
angle2 = angle.degrees # trying to become degrees
#
puts "@lwidthplus",@lwidthplus #gives >> 7.8740157480315 (equiv. to 20)
puts "@run",@run #gives >> 11.8110236220472(equiv. to 30)
puts angle #gives >> 1.5574077246549, should be 0,6666666 ( = 20/30 >> about 34 degr.)
puts angle2 #gives >> 0.0271818925912213
#
tr = Geom;;Transformation.rotation(point,@vector,angle2) # turnes somehow
group.entities.transform_entities(tr, group.entities.to_a)
#
@m_pf_l = group.to_component
defn = @m_pf_l.definition
defn.name = "@m_pf_l"
it must be something very simple....but i cannot see it!
stan
hi,
i cannot find my mistake
with
@run = 30
@lwidthplus = 20
the formula
angle2 = (Math.tan(@lwidthplus/@run))*180/Math::PI
does not give me the right angle.
as far , as i understand
(Math.tan(@lwidthplus/@run)) gives me the RAD
and
*180/Math::PI should give me the degrees
any idea, where my mistake is?
thanx stan
hi tig, thanx, that's the point.
i understood before, that "transforming " the container (group or component) has to be applied to the instances, too.
with your code i now have the desired access to its entities! wonderfull, thanx for that,
it works now , every transformation is passed to the component instances.
in that point, the ruby-skp-api gives too few syntax to play with...
thank you.
stan
hi tig,
yes, my problem was the right asignment...but to find this out with the ruby-api... :_)
so for one component it work for me.
now i have an interesting issue with that:
i learned, that when i turn THE COMPONENT like this and
then make a instance (copy),
the new instance is not turned (transformed). i want to have the MASTER ELEMENT prepared and ready for copying.
so i tried to turn the GROUP, before the component is created out of it:
group = entities.add_group
@entities2 = group.entities
new_line = @entities2.add_line pfm1, pfm2 # gives a vertical line
@vector = new_line.line[1]
point = [0,0,0]
transformation = Geom;;Transformation.rotation (point, @vector, 45.degrees)
group.transform!(transformation)
# and then create a component
@m_pf_l = group.to_component
defn = @m_pf_l.definition
defn.name = "@m_pf_l"
componentinstance =
entities.add_instance(@m_pf_l.definition, pf1) # pf1 is a defined point
to my surprise,
in the copy of the component then (new instance), the elements are also NOT TURNED.
mysterious for me...
stan
hi,
i just cant get thru the syntax of transformations and need a small help at one point:
i have a component defined and would like tu turn it along the vector-axis.
so (all within a module)
but
@m_pf_l = group.to_component # existng group to component
defn = @m_pf_l.definition
defn.name = "@m_pf_l"
point = [0,0,0] # my point
transformation = Geom;;Transformation.rotation point, vector, 45
t = defn.transformation
this code does not work. i know, i have a wrong connection to the component instance (i tried differet syntax-variantions), but
i don't want to use the code from the api-guide, since there they ADD an instance, but i want to turn the existing component.
so again, thanx for the tip
stan
@ tig
hi tig, thanx,
with
def delete_model_zf
#***************************************************************************
@putswitch = 0
begin
@group_stair.erase!
rescue
end
end
it worked, as soon as i understood, that rescue can also be NOTHING, so the code runs thru end the method ends
@ dan, thanx,
this is still higher programming syntax (for my brain), i tried to encapsulate in
require("sketchup.rb")
MODULE AMS
MODULE 01.rb // is it right to put hier 01.rb ??? (the work-name of the ruby)
MY CODE
END MODULE
END AMS,
but have errors. have to work it out! but i would like to put the ruby into a proper form for the first release / check. i'll get back to this later.
hi dan, have to correct it ( was only for me to see it better while working on it), thanx. (and i already study the files, you recomend for newbie's...but it's a lot to learn, of course)
and i have to correct my previous statement:
my "checking" code does not work in a new opended file. it again reports a deleted group, while searching for it.
but, as soon as i create the first group and the activate the checking-line, it works.
so now a question:
is there a way to define 1 variable (true or false) ON LOAD ?
so this variable would only be "true" when sketchup is opened and before my ruby script runs for the first time (i could overwite it then for the active session)?
then i could run the checking code "unless onload == true " or something like that.
ragrds stan
hi tig and yes,
@group_STAIR.erase! if @group_STAIR.valid?
works perfect.
another advantage: when i generate my group and copy it manually to the desired place
and then call the ruby again, the original is beeing deleted and the copy remains.
that is, what i wanted to achieve: when the user is satisfied with the result, he can either make a copy or make a component out of the group.
next step is done!
thanx a lot
stan
ps: (on the other hand i was not sure in example 2 and 3, why they did not work for me, i still investigate, must be the NAME definition, i think).
hello,
i went thru all snippets,
but
how can i check, if a group @NAME
exists or not in the actve model.
situation
i create a group NAME by ruby
then it either is deleted or not
whith the next call ruby shall check, if group NAME is there
if not, create it
if so, delete and create it new
my trial:
entities = @NAME.entities
entity1 = entities[1]
status = entity1.valid?
unless status == true
model = Sketchup.active_model
@NAME.erase!
end
reports an not existing group, so no check is possible
tahnx for helping on this

what i want to achieve, is to create a component in step 1 of the loop and copy this component to points pf[mth] in the other steps of the loop.
i desperately try, but always get an error for copyying the component.
i also tried:
explode the group, in which the component is created, but then there is not the component left, but the group (no idea how)
so maybe someone has an idea...
thank you
stan
hi, thank you all, i tried to put my groups in the suggested ways into a loop, but i always get errors. with '@@groups' i would reach all grups, wouldn't i ?
i will try to describe the whole problem:
i have a defined amount of groups with one basic construction point (thanx dan), the amount changes by user input, so it must be variable, so there may be 2 or 20 @group_handlauf_mitte - groups.
@group_handlauf_mitte1
@group_handlauf_mitte2
@group_handlauf_mitte3
@group_handlauf_mitte4
and so on
i cannot find out, how can i access those 'group_handlauf_mitte ' groups in a loop to be able to select a group by
@group_handlauf_mitte[index].entities. (my index here ist PODESTNR)
i also tried to create the group name as a string-combination within a loop
for step 1..20
a = "group" + step.tp_s.name
a.name = a
end
but that's obviously not working , too.
at the moment i have to define like this:
if @podestnr == 1
entities = @group_handlauf_mitte1.entities
new_line = entities.add_line rl13, rl14
entities = @group_handlauf_mitte1.entities
elsif @podestnr == 2
entities = @group_handlauf_mitte2.entities
new_line = entities.add_line rl13, rl14
entities = @group_handlauf_mitte2.entities
elsif @podestnr == 3
entities = @group_handlauf_mitte3.entities
new_line = entities.add_line rl13, rl14
entities = @group_handlauf_mitte3.entities
elsif @podestnr == 4
entities = @group_handlauf_mitte4.entities
new_line = entities.add_line rl13, rl14
entities = @group_handlauf_mitte4.entities
end
instead of this i would like to make a loop in which STEP decides, which grop's entities will become ENTITIES, but only for those groups, not all groups i have.
hopefully i can once understand the syntax for group selection by index, because i could then make the ruby-code many times shorter.
in this loop i need the griup name 1,2,3,4 to become dependent from the index MTH
model = Sketchup.active_model
y1 = 0 - @run ## the overall variables come from earlier code !!!
y2 = 0
y3 = @run
z = @rise
pf = []
for mth in 1..10
entities = @group_handlauf_mitte1.entities ### MTH instead of 1 needed
entities.erase_entities entities[0]
rl1 = [0, y1, 0]
rl2 = [0, y2, z]
group = @group_handlauf_mitte1 = entities.add_group ### MTH instead of 1 needed
entities2 = @group_handlauf_mitte1.entities ### MTH instead of 1 needed
new_line = entities2.add_line rl1, rl2
length = new_line.length
pf[mth] = [0, 0 - @run+@run*@il*(mth-1)+@run*@la*(mth-1)+@ro.abs, (mth-1)*@il*@rise+@sr] #mitte
#point1 = Geom;;Point3d.new pf51
#constpoint = entities.add_cpoint point1
centerpoint = pf[mth]
new_line = entities2.add_line rl1, rl2
vector = new_line.line[1]
vector2 = vector.normalize!
edges = entities2.add_circle centerpoint, vector2, @thradius
kreis = entities2.add_face edges
entity1 = entities[0]
kurvem = entity1.all_connected
status1 = kreis.followme kurvem
end
thanx for helping

hi,
is it possible to create and define GROUPS as ARRAY?
example: #create needed groups for later element assignment
$groupname[0] = Sketchup.active_model.entities.add_group
$groupname[0].entities.add_line([0,-50,0],[0,-50,140]) #element [0] will be later deleted
$groupname[0] = "$groupname[0]"
$groupname[1] = Sketchup.active_model.entities.add_group
$groupname[1].entities.add_line([0,-50,0],[0,-50,140]) #element [0] will be later deleted
$groupname[1] = "$groupname[1]"
.....
after this, one could assign elements to those groups within a loop using a
the loop-step as the arry-index
thanx stan
hi tig, thanx,
this work well, one step further for me, now i can identify the "children" of the masters exactly. that's perfect.
just to understand exactly:
a name of component instance defined by this method appears in the field "description"
a group named by group.name = "xxx" appears in the filed "name"
is there also a way to NAME a component or its instance besides a description?
thanx

hello,
i went thru all topics dealing with component naming,
but i cannot find a solution.
i would like to give a name to a created component by this code:
######## start code
model = Sketchup.active_model
entities = model.active_entities
rl1 = [0, y1, 0]
rl2 = [0, y2, z]
group = entities.add_group
entities2 = group.entities
new_line = entities2.add_line rl1, rl2
length = new_line.length
centerpoint = rl1
# Create a circle perpendicular to the normal or Z axis
vector = rl2
vector2 = vector.normalize!
edges = entities2.add_circle centerpoint, vector2, $thradius
kreis = entities2.add_face edges
kreis.pushpull -(5/$faktor)/100
$masterrailingtms = group.to_component
# HERE I WOULD LIKE TO DEFINE A NAME FOR THIS NEW COMPONENT, WHICH I CAN SEE IN IN SKP ENTITY-INORMATION-WINDOW. this name also hopefully appears in the copied instances of this component, but most important is the name for component [0]
######## end code
can somebody help me?
thanx

hello ruby friends,
i took 2 weeks off to study some programminmg guides etc. for ruby. i could solve some variable-problems, but i cannot find a solution for the following:
i want to define some master-components, which are copied later in the routine as instances.
this works well, when i define one component after each other (linear).
this all happens in one routine like this:
def_programm
define compo 1
define compo 2
define compo 3
some other tasks
copy compo 1 to instance .....
copy compo 2 to instance .....
copy compo 3 to instance .....
end
BUT
when i try to make the component definition within a LOOP and define the compnent'S name as ARRAY,
the components are again created, ok, but the creation of INSTANCES report, that they cannot find a deleted master component.
so it seems, that the components made within a loop are not visible for the rest of the program.
i am not sure, if i could explain my problem. in one other topics i was said, i should post the parts of programm code in some special way: could someone tell me, how to do it?
until then, here is the loop for the component - creation:
# edit 131107
