hi,
is there any hidden parameter in the api (now in skp 2017), that would alow me to save a compo-definition to a file (name.skp) in version 2015 instead of the version of the opened skp-session?
the reason is, that i have a version of a vis-program, which does not import version 2017-files.
(at the moment i have to re-open them in a new skp-session and save_as....)

or is there a converter, which could be launched from ruby-api to batch-convert the saved compos in a selected folder?

than in advance.

hello to all
and thanx for checking my problem. i will check the specs in detail,

hello,
up to v 2016 i could work on older laptops,
v 2017 now reports a missing open gl etc.

is it possible to run 2017 somehow also on older systems (which still work well ? even a certain loss of performance would not be a problem....

thanx

edit 170122-found the string-file for style names in the programm-dir........one step further.....

hello,
maybe somebody has an idea for the following problem:

in german-skp-version:

• when i iterate thru model.styles via ruby and display their names,
  the styles are shown as following (edit: in ruby concole, not skp-style-menu):

• own styles with user-name or edited styles : name in german

• original styles (like chosen from style-submenues and un-edited: in english (skp-basic name in [style-name] form

• in the style menu the name is always shown in german

as soon as i click on the german name in the style menu (top line in the style menu), the style gets converted and will be shown now (ruby-iteration) in german in the ruby console.

NOW:

how can i retrieve the german name for the english name and vice versa via ruby? is it a hash?

the problem is:

i have an input menu, where i can copy the name from the skp-menu and search for the style.
but here

not-edited original styles cannot be found, because

• skp-menu offers the GERMAN NAME (which i copy via c&p)
• ruby iterates in the english namespace and cannot find this style via name-input

any solution or tip?

thanx a lot in advance

hi,

within my own class (tool) i use shift, ctrl and alt for alternative mouse functions.

is it possible to override the native alt-function (menu-hi-lite) temporarily within a tool

and set it back , when the tool is finished?

i canot find any topic about this ....

thanx

hi,
this one does not seem to work. i wonder, if a layer.name can be a condition? no info in api....

model = Sketchup.active_model
entities = model.entities

entities.each { |m|
puts "iterating m"
	if m.is_a?(Sketchup;;Group)
		e = m.entities
			e.each { |f|
			puts "iterating f"
			    if f.is_a?(Sketchup;;Group) and f.layer == "layername"
					puts f.layer
						entities2 = f.entities
							entities2.each { |g|
							puts "moving entities"
							newlayer = g.layer = "Layer0"
								
									}
					end				
					}#f
		end
	}#m
end#def

thanx
stan

edit: just found out, that

@unknownuser said:

if f.is_a?(Sketchup::Group) and f.layer.name == "layername"

works.

hi and thanx to both,
@ tig: yes, i also use puts-tags to follow the code in the console , whit line-number-output to see, in which code -line the puts is.
i will try out all the break, next etc. functions. thanx for this?

and @tt_su

yes, interaction with the viewport was exactly, what i hoped for, so i could inspect the geometry at any stage ot the running code. (break - inspect geometry - go on....). the rest is still tooooo 'high' for me, although i already 'speak' a bit ruby...-:)

stan

hi,
when i have

model = Sketchup.active_model
sel = model.selection

and create a edge-copy from a given edge (from an edge-array : edges)

entities2 = Sketchup.active_model.entities
vertex = edges[0].start
pt_start = vertex.position
			
vertex = edges[0].end
pt_end = vertex.position
					
edge2 = entities2.add_line(pt_start, pt_end)

how could i ADD the new edge2 to the sel ??? (merge ?)
is it possible?

after this the further code should realise sel incl. the new adge2 as USER's SELECTION .

thanx

hi,
is there a function in the UI, where i could

stop the ruby at this point and exit,

to check the actual state of elements in sketchup directly?

thanx
stan

hi tt,
to finish this topic,
i learned how to identify a surface and handle its parts (faces) and now i can manupulate its elements, as needed.

thanx to all in this topic for helping and ttheir ideas.

hi jolran,

1. i'll test your new idea later tonight, but i had the formula with origin

tra = @main_element.transformation.origin

already and it gave me the origin of the group at the point, where it was made, not to absolute [0,0,0]. but we shall see !!

2. bounding box : i tried this, but i don't need the lowest point of a group, but one special corner within it, so lowest z of the bbox does not help here.
   and when i retrieve the bbox of the nested element, itz again is relative, not absolute.

seems to be tricky somehow....

thanx
stan

hi tig,
i understood and made some tests.
but if i have a group named

@main_element (i persume it has a transformation, even it is not moved or anything else)
and say

tra = @main_element.transformation

i get errors , since my syntax is wrong.

could you give me the syntax for retrieving the transformation from a group?

i tried a lot of ways, but always get errors.

thank you!
stan

edit:
when i define tra as

tra = @main_element.transformation.to_a

i get

tra [1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0]

how can i interpret the numbers?

edit 2:
when i move a group in Z+, tra becomes

tra [1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1968.503937007874, 1.0]

so 14th position seems to give the height.

the problem is, that if i create a plane in a certain height (Z+), the transformation counts this as 0,0,0 .
pos. 14 changes first, when i move the group from its origin place, where it was created.......this transformation is not related to absolute zero....

hi and thanx,
so if understand right,
this would sort the array of given points and find out the one with the highest z, right? (nice code, btw).

so if if i had

pt1=[0,0,5]
pt2=[0,0,6]

it would return zmax = 6 , right?

my problem is, that when i retrieve points WITHIN a group, i get relative coordinates, not absolute. and since the group has no transformation, i again don't get ABSOLUTE coordinates ( with ABSOLUTE i hope to get the Z-zero of sketchup space, independent of, if the user changes the coordinate-origin (axes).

maybe there is a way to get ABSOLUTE COORDINATES of any point outside or inside of grous/components?

i am not yet familiar with " keys" etc..... -:)

Go to the Ruby Resources "Sticky Thread" here:
RUBY PROGRAMMING REFERENCES

Get the CHM files for whatever version Ruby your SketchUp is using.
SketchUp v8, 2013 and earlier uses Ruby 1.8.6
(some earlier version used Ruby 1.8.5 and 1.8.0, FYI)

THEN ... lookup the Hash#keys() method

hi dan, thanx,
next one to be studied (of still so many....). -:)

just to be sure of universality (ruby-versions), i run the code always in 2014 and v8 in win7, vista and xp....

@thomthom said:

Where did you get @surface from?

hi thomthom,

the method is

having a smooth mesh with any loops projected on it and intesect

selection of one or more surfaces by user and calling the method

iterating thru selected surfaces

iteration thru all elements within one of them

further operation with edges within the surface, especially the smooth ones

this peace of code for surface works super for me.

hi,
i get object's height by

tra = @main_element.transformation.origin
reference_height = tra[2]

but this gives me the vector from the position in space, where the @main_element was created.

i would like to calculate the height of a defined point (say toppoint of a bbox)
above absolute sketchup 0,0,0.

since this is not a transfromation, is there an absolute - z - variable somewhere?

thanx

The return is an Array of all the Faces from any surface containing the Face passed as the argument. If the Face is not in a surface, the return will be an empty array.

hello,
thanx a lot. yes,

in the mean time i renamed the array to @surface.keys and got the array back. works perfectly.

i have to find out, if there is a way to return this array without renaming (return xxxx ???)

stan

hi,
this seems to be an interesting approach, but
what is returned by the method?

is it an array of elements, i can iterate?
i am not yet familiar with "keys" etc..... -:)

if this gives back all entities of the "surface", how could i iterate thru it?
when i try, i get errors,
thanx

hi tig,

that's fantastic,

point 2 : solved ( i already though of retrieving the points , but vertices work perfectly!

for point 1:

got it working, super. thanx.

by the way, is there a code for deliting an array of edges directly ? or do i have to iterate thru the array and erase one after another?

in my case i create a copy of a face in the new group (>> vertices)
and wantto delete the original entity incl. edges.

thanx a lot
stan

hi,
i wopuld be greatful for a small tip:

i have a @main_element,
which contains some faces

when i iterate thru the entities, i can check the normal, see the top face and push pull

i also can create a new group within the @main_element-container and put an edge in it.

buit when i want to put one of the @ main_element's entities (here it is a face) into this new group,
i get a "parent" problem, which i don't understand:

@selection.each { |entity|
	
		if entity.is_a?(Sketchup;;Face) 
		
			check_normal_for_horizontal(entity) #my own method
			puts @bgf_count_normal # 1 is face top
			if @bgf_count_normal == 1
				puts "---FACE UP ... IN MAIN-ELEMENT"
				#			
				entities = @main_element.entities
                                #
				group = entities.add_group
				entities2 = group.entities
				point1 = Geom;;Point3d.new(0,0,0)
				point2 = Geom;;Point3d.new(2000,200,200) #works
 				edges = entities2.add_edges point1, point2
				#
				#			
				loop = entity.outer_loop # does not work
				edgearray = loop.edges
                                floor = entities2.add_face(edgearray)
                        end
                 end
                 }

why does the new face from edgearray not appear in the group?

info from console:

###############
---FACE UP ... IN MAIN-ELEMENT
Error: #<ArgumentError: Edge has different parent>
C:/Program Files (x86)/SketchUp/SketchUp 2014/Tools/02.rb:959:in `add_face'
