[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:

Code: Select all

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.

SpeedTest
is_a? - 0.36c
kind_of? - 0.39c
class - 0.422c
typename - 1.313c

Model Statistics:
edges = 48981
faces = 8009
groups = 729
components = 365
construction_lines = 1
construction_points = 4
images = 3
section_planes = 4
texts = 4
others = 2

[thomthom]

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

Thanks for posting this test.

[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?() !!!

Here's v1.1 viewtopic.php?p=161963#p161963

[thomthom]

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

[AlexMozg]

...I didn't realise it was so much slower to use typename=="".
.....

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

Model Statistics:
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

[3dsmax9]

a tool bar will be very great with this script

[irwanwr]

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

[Ivancho]

NICE!!

[hygicell]

I have lost a component somewhere in my drawing
to find it, I pasted a second one in a visible place
when I select this, the entity info clearly says Component (2 in model)
with the components window context menu, I selected all components
I thought then, if I could hide the rest of the model, I would easily spot where the original one is
but view/hide rest of model doesn't work unless you are inside the component,
which means you can select only one of both, and the other one is deselected
please help
Frank

View > Hidden Geometry ON will show all hidden objects.
If it's on a Layer that is OFF you won't see it though...
The Outliner will also show all instances that are on ON Layers...
You can select them in the Outliner and they select in the model.
