[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.

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...

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...

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!

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!

My model statistics:

Model 68.4 Mb:
Edges 485016
Faces 128906
Component Instances 6055
Groups 3078
Section Planes 4

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

Very good !

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

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

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

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