hi everybody,
thanx for this interesting discussion,

and yes, tig's way worls perfectly, so it is possible to immitate the mouse movement of single entities in any angle and direction.
fantastic!

                new_line10 = entities31.add_line pts[1], pts[0]
		tr = Geom;;Transformation.rotation(pts_senkrecht1,@vector,@angle_m.degrees)
		group31.entities.transform_entities(tr, new_line10)

#MOVE 1 FACE  >>>> number
						
		distance_m_result = @carrier_w *@totaloffset_x_center/@run 
		vector2 = new_line10.line[1]
		vector2.length = distance_m_result.abs
		
		tr = Geom;;Transformation.translation(vector2)
		group31.entities.transform_entities(tr,group31.entities[number])

hi,
again i cannot really find a solution in the api-description:

when i have a group of 100 entities (edges and faces) and i know, that entity(50) is always the one i have to transform (it is a face),

how can i MOVE this face (like with the mouse) , so that all connected edges and faces adapt automatically?

i have the distance, the vector and the number of the entity.

thanx for helping!
stan

merry x-mas to all helpers in the forum.

thanx a lot!

stan

oh yes, and how it went......i am just about to begin to understand the basics.

but i am proud of having the first version of my ruby nearly finished. the code is still more linear then intelligent, but will be improved step by step.

and one day, who knows, i also can deal with metrices in the 5th dimension.

merry x-mass

hi and thanx, this is interesting, for me still a bit too high, although i understand it basically, but the time will come.....

btw., i could solve my problem and can now generate points at the cross-point of lines (from edges).

thanx to all, once again.
stan

edit:
found out:
edges are numbered first
then the faces (depending on the order of the edges...
so it is rather easy to point out, which numbers are for the faces and delete thems selectivlely.
stan

hello,
maybe i may expand this topic a bit:

i just look for a way, how to identify the single faces on a cuboid (let's say, it is a cube, so it has 6 faces).

i would like to delete two of the four vertical faces,
so i cannot identify them by the normal vector only (just excluding the vertical ones).

since the element are turned in different angles, also x- or y- direction is also not the exclusive factor.

so:

is there a way to find out the number of face (face 0 .. 5) somehow, to be sure, that these faces have always this number 'in the row' and then i could delete them by

face[x].erase! in EVERY 6-FACE-CUBOID

or something like that.

thanx stan

hi,
problem solved, it was sketchy physics. i will try to redifine my code later, maybe i will find the problem.

hi,
from here the links are broken.
maybe only free for the "expert group" ?

regards stan

hi tt, although i synchronise the plugin-folders carefully,
making the win7 folder empty in deed was the solution.

so now i have to find out , which plugin has a conflict and can correct my code.

it was the first time, something like that happend. interesting!

thanx a lot for your "expert's eye".

ps: i just wonder, where to send all the cookies afterwards,,,,

hi,
i have a strange problem:

in windows vista / skp 8 and skp 6 this peace of code (within the whole ruby) works perfectly (the group is copied, named and transformed copy-times:

angle = @arena_angle_half*2
		puts angle

		entities = @group_stair.entities
		group_arena = entities.add_group

			for copy in 1..@arena_angle_devider
			angle1 = copy *  angle
			group = @group_stair.copy
3863			group.name = "arena-copy" + copy.to_s
			tr = Geom;;Transformation.rotation(point,vector,angle1)
			@entities2.transform_entities(tr, group.entities.to_a)
			end

to my surprise, it does not work on

win 7 / skp 8
win xp / skp 8

this error is reported in the console

Error: #<NoMethodError: undefined method name=' for nil:NilClass> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:3863:in arena'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:3860:in each' C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:3860:in arena'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/01.rb:212

has anybody an idea, what this problem could be?

thank you very much!

stan

hey, very good idea to go with win.api

i use this trick in my excel basic sound database to controll external programs from the code.
i will try tonight and report!

thanx stan

hi tt & tig,
thanx for that, i am going to dive now into the deep space line for the edges and hopefuly come back much smarter than before!

thanx for the great help!!! what would all the ruby - manuals be without you all in this forum....

hi tt,
yes, i was just about to put edit 2 in the text:

entities2 = Sketchup.active_model.entities
@centerpointline_left = entities2.add_line @bottom_c_point1_l,@bottom_m_point2_l
@centerpointline_right = entities2.add_line @bottom_c_point1_r,@bottom_m_point2_r

point = Geom.intersect_line_line (@centerpointline_left, @centerpointline_right)

the lines are created, the crosspoint is there (can catch a line),

but ruby conole still reports

"
Error: #<TypeError: wrong argument type Sketchup::Edge (expected Array)>
C:/Program Files/Google/Google SketchUp 8/Plugins/01.rb:3783:in intersect_line_line' C:/Program Files/Google/Google SketchUp 8/Plugins/01.rb:3783:in top_handrails'

stan

hi,
when i generate a crosspoint from two lines:

ector = @centerpointline_left.start.position.vector_to(@centerpointline_left.end.position)
vector.length = @centerpointline_left.length
vector2 = @centerpointline_right.start.position.vector_to(@centerpointline_right.end.position)
vector2.length = @centerpointline_right.length
v = vector.cross vector2

where the centerpoint-lines are 100% crossing,
i get the point v (sort of virtual point, i think).

but now i would like to place a c_point at this position

this:

point1 = Geom;;Point3d.new v

does not work.

also the

d = vector.dot vector2

does not give me the point.

thanx for helping.
stan

edit 1 : now i understand, that v is also a vector. the problem is still, how to place the 3d-point!

thanx for ideas.

hi,
is there a way to hide the ruby panel from the code?

switch on: Sketchup.send_action "showRubyPanel:" works.

switch off : Sketchup.send_action "hideRubyPanel:" ?????

thanx stan

hi tig,
great , good formulas for further studies.
my code works now, by the way.

just to precise my informations:

i understand, that "atan" only works for right-angled triangles (one angle = 90 degrees),
but: is the sum of angles not 180 degrees in all triangles?
so the criterium is the right angle, not the sum of 180 °, right ?

"jumbling up radians and degrees [again]" _:)
yes, i still sometimes mix it somehow, but i try to keep all calculaction in skp-origin
and only to display in the console in degrees. seems to work now! _

so thanx again, all your tips makes my learning much easier!

btw.: when a beta of the ruby is done and i made my tests, do you think, you and maybe somebody else , too, could check it on his machine?

i have lots of rubys in my sketchup, so the compatibility here is ok, but who knows...!!!

thanx stan

hi there,
so i stick in place with a math-problem:

let us assume, i have

two lines in a traingle defined with
a1
b1

i can count the angle by

@mainangle_l = Math;;atan(a1/b1).radians

puts also gives me the right angle in the console (compared with the drawing = check)

in the next step i have to calculate another triangle, same angle, but have values
@mainangle_l
c2

BUT

a2 = c2 * Math.sin(@mainangle_l))

does not give me the right value for a2

i tried different variations of the syntax, but no way to get it.

obviously i define the Math-function in a wrong way. but in the api, i canot find examples.

can anybody help fo rgeneral understanding of trigon. functions??

thanx a lot!!!

stan

hi tig,
thanx so much, but this one really makes me crazy.....

what ever i do , the move! - instructions MOVES but does not copy, it's magical...( i tried all your codes, the code from the api....)

my code so far ( i am on the level of @entities2 (coming from a method above this one)

new_line1 = @entities2.add_line @rl1a, @rl2a # define line for vector
length = new_line1.length
#									
rasterarray_h = length.divmod(5.0/@faktor/@teiler_cm )
raster = length / rasterarray_h[0] # calculate gap between verticals ( == true length)
#
# so the raster is the 3d-distance on the vector from new_line1
#
group = @entities2.add_group
entities_stab = group.entities
@rl1a = [(fl)*  const1+var2*var3  , (fl)*  const2+var4 , 0 + (fl)*(@pmod * @rise)+@railsgapunten]
@rl2a = [(fl)*  const1+var2*var3  , (fl)*  const2+var4 , 0 + (fl)*(@pmod * @rise) + var6+@railsgapunten]
#
edge = entities_stab.add_line @rl1a, @rl2a # create 1st vertical
#			
#entities = @entities2 # tried this, too..
#			
for v_line in 1..rasterarray_h[0]
#			
    vector = new_line1.start.position.vector_to(new_line1.end.position)
    distance = v_line*raster
    vector.length = v_line*raster/2
#
    group2 = group.copy
    group2 = group.move!(vector)  
# and the line is moved, not copied....or the original group disappears? there shold be lots of vertical lines in distance of "raster".....
#			
end
#

grrrrhhh....
i make a break now, the brain is just about to explode.......

hi,
i would like to discuss the basic structure of how skp works:

i normaly generate a model per ruby (some elements in some groups and some components) , which are all packed

in a master group.

so i can delete the whole thing by deleting the master group from ruby.

ok.

when i again genarate the object with same parameters, the components have additional numbers ( like
@m_pf_l#27 , while starting with @m_pf_l before 1st delete.)

so what happens? if i delete the master group WITH all components in it, does sketchup keep a table of names of deleted compnents or even all the components ??? my file gets bigger after a certain time, so maybe this is also a point.

so is is possible to purge the file from ruby , but to purge only the elements from the latest deleted group?
or shal i somehow delete or component instances WITHIN the master group, before deleting the master group itself?

i found this in the forum:

Sketchup.active_model.definitions["CompoName"].instances.each{|e|e.erase!}, but don't know, if it will work for the master group only , or delete also its copies, which the user wants to keep.

thanx
stan

hi tig,
understood, works perfect !

model = Sketchup.active_model
materials = model.materials

names = ["zf_carrier", "zf_step", "zf_landing", "zf_fill", "zf_wange", "zf_pfosten", "zf_handlauf", "zf_bars", "zf_topstift", "zf_railplate"]

color_val = [[112,128,144],[200,220,200],[230,230,230],[100,120,100],[255,0,0],[0,255,0],[0,20,255],[10,10,10],[60,180,180],[0,206,209]]

zf_c = 10
	for col in 0..zf_c-1
		if @pref2 == "no" #option for the user for coloured screen output (in my ruby-preferences)
	        material_name = names[col]
			unless material = materials[material_name]
			material = materials.add(material_name)
		        end
		material.color = Sketchup;;Color.new color_val[col]

		elsif @pref2 == "yes" #option for the user for monochrome screen (in my ruby-preferences)
		material_name = names[col]
			unless material = materials[material_name]
			material = materials.add(material_name)
		        end
		material.color = Sketchup;;Color.new(230,230,230)
	end
end

thanx stan
