Ruby Script question re soften certain lines only

pmolsen

How hard would it be to write a Ruby Script that made all vertical lines in a model soft and smooth please?

Easy.


model = Sketchup.active_model

model.entities.each { |e|
	if e.is_a?(Sketchup;;Edge) && e.line[1].parallel?(Z_AXIS)
		e.soft = true
		e.smooth = true
	end
}
model.definitions.each { |d|
	if e.is_a?(Sketchup;;Edge) && e.line[1].parallel?(Z_AXIS)
		e.soft = true
		e.smooth = true
	end
}

(Sorry - don't have time to wrap it up in menu system atm)

Hey, thanks a lot for that quick response.

Actually what I should really have asked is how do I select all vertical lines. Then I can do whatever I want with them.

Tried to finish it off but getting syntax error on the last line. Never created one before. Any ideas please? File is called softenv.rb and is in the plugins folder:

Soften all vertical lines in a model

require 'sketchup.rb'

def soften_vert

model = Sketchup.active_model

model.entities.each { |e|
if e.is_a?(Sketchup::Edge) && e.line[1].parallel?(Z_AXIS)
e.soft = true
e.smooth = true
end
}
model.definitions.each { |d|
if e.is_a?(Sketchup::Edge) && e.line[1].parallel?(Z_AXIS)
e.soft = true
e.smooth = true
end
}

if( not file_loaded?("softenv.rb") )
add_separator_to_menu("Plugins")
UI.menu("Plugins").add_item("Soften vertical lines") { soften_vert }

end

file_loaded("softenv.rb")

Ok, I think I was missing an "end" on the last if statement. Fixed that and now get no syntax errors but the option does not appear on the Plugins menu when I restart SU...

Shuffled things around a bit by copying other scripts and got the menu item to appear. Not sure how. But when I select the option nothing happens:

Soften all vertical lines in a model

require 'sketchup.rb'

def abc
model = Sketchup.active_model

model.entities.each { |e|
if e.is_a?(Sketchup::Edge) && e.line[1].parallel?(Z_AXIS)
e.soft = true
e.smooth = true
end
}
model.definitions.each { |d|
if e.is_a?(Sketchup::Edge) && e.line[1].parallel?(Z_AXIS)
e.soft = true
e.smooth = true
end
}

end

name = "softenv.rb"
unless file_loaded?(name)
UI.menu("Plugins").add_item("Soften verticals") { abc }
file_loaded name
end
