[Plugin] #SelectionHideShow.rb v1.1

[TIG]

#SelectionHideShow.rb adds a context-menu sub-menu with various Selection, Hide and UnHide tools, such as 'Invert Selection', 'Hide/UnHide Selection', 'UnHide All Active' etc...#SelectionHideShow.rb
Edit:
v1.1 Now tests with ".is_a?" to speed-up and avoids testing already unique groups[after AlexM's advice].

Very practical!

[Mr S]

Great!
I asked for this a while ago.
I suggested it was something that should be a standard feature in SketchUp
Now it is. Thanks for another great contribution.

Mr S

Thanks TIG. However I expected to see Reverse Faces in there too.

[erikB]

Thanks TIG, and I second the request made by Boofredlay.

Reverse and Orient faces is already built-in on the context-menu - near the top [as are some other 'select tools']... adding them would only duplicate stuff...

TIG
Why constantly to use the method of group_miner, when in him practically is not there a necessity?
Why to apply properties to entity, when are new properties of entity equal to the applied properties?
These questions are linked at a speed of implementation of script on the large scenes.

Example of considerable increase of speed of implementation of script:

class Sketchup;;Group
    def definition
        self.entities.parent
    end
end
def SelectionTool;;group_miner(ents)
    ents.each do |e|
        if e.is_a? Sketchup;;Group
            e.make_unique if e.definition.instances.length > 1
            SelectionTool;;group_miner(e.entities)
        end
    end
end

At the use of method of typename speed of implementation of script goes down in once or twice!
It would be desirable to correct these shortages...

[Chris Fullmer]

Alex, I have not run any tests on typename, but I use it regularly. Are you saying that it is much slower than .is_a?

I'd rather use the faster method too, I just never knew there was a faster one. I'm sure TIG isn't using a slow method on purpose either...

Easily to check...
The more elements in the model - the better results script.

Not plugin!

[thomthom]

That's some interesting numbers. I've always used k ind_of? - wasn't aware of the is_a?. then again, I've never tested the speed of methods either.

Thanks for posting this test.

[thomthom]

Maybe we could add this info to a new stickcy where we collect such useful tips and info?

[TIG]

Thanks Alex - you've probably noticed I used the .is_a? test everywhere else in the script - however, I didn't realise it was so much slower to use typename=="".
I've also incorporated my own version of your group_miner speed-up suggestion that now avoids testing groups that area already unique...

I just need to edit ALL of my other scripts to change e.typename=="" to e.is_a?() !!!

.....

For a model ot a few kilobytes to 10 megabyte of substantial difference it is not, but my models ot 40 to 75 megabyte!

P.S.
It was even necessary to write the analogue of SketchUp Text tool, because a standard tool begins to work very long.

[bianhai]

Very good !

Hmm... .kind_of? is an alias for .is_a? - Is that fraction of a differences just some other random outside co-incidence?

[thomthom]

I did a somewhat larger test. By the looks of it .is_a?, .kind_of? and .class are pretty much the same. I take the differences due to other system factors at the time of execution.

AT - SpeedTest:
is_a? - 0.89c
kind_of? - 0.782c
class - 0.875c
typename - 2.297c

edges = 159630

[thomthom]

Much larger test. (did have a few programs open while I did the tests.)

AT - SpeedTest:
is_a? - 16.297c
kind_of? - 16.141c
class - 18.703c
typename - 88.703c

a tool bar will be very great with this script

[irwanwr]

i think i need this plugin
thank you in advance, sir.
