Mac and Windows 'New Model' differences...

driven · 11 Feb 2016, 18:35

I'm looking at ways to optimise some code and have made a couple of methods that both work on a mac...

however, I had reports from testers that neither work on a PC...

Is it possible to have either work on a PC?

the example writes a skp to your Desktop, unless you change the path...

to run, paste code into RC and hit return...

then type auto_create and hit return...

# Test file is 5MB,  first is quicker if selection is empty?...
def empty_selection
	new_skp = File.expand_path("~/Desktop/john_test1.skp")
	begin
         # original stays open and new opens in front [0.14629]
	  Sketchup.active_model.save_copy(new_skp)
	rescue # for un-saved original
          # original closes and new opens on mac [1.222455]
	  Sketchup.active_model.save(new_skp)
	end
        # next is not needed for either save or save_as on mac
        # Sketchup.open_file(new_skp) #with save_copy() original stays open [1.920228]
        # just show the ruby works in the new window...
	Sketchup.active_model.rendering_options['BackgroundColor'] = 'red'
end

# faster than collecting and deleting unwanted entities on large complex models...
# I have I mac cocoa utility to avoid using .send_action(), 
# but this is a little faster and 'should' be cross platform...
def with_selection
	new_skp = File.expand_path("~/Desktop/john_test2.skp")
	Sketchup.send_action('selectSelectionTool;') # copy needs a trigger on mac for copy to work
	Sketchup.send_action('copy;')
	Sketchup.send_action('newDocument;')
	Sketchup.send_action('pasteInPlace;')
	sel = Sketchup.active_model.selection
	view = Sketchup.active_model.active_view
	view.zoom(sel)
       # original stays open time depends on the selection size...
	Sketchup.active_model.save(new_skp)
        # just show the ruby works in the new window...
	Sketchup.active_model.rendering_options['BackgroundColor'] = 'green'
end

def auto_create
	t1 = Time.now
	sel = Sketchup.active_model.selection
	sel.empty? ? empty_selection ; with_selection
	p time = Time.now - t1
	UI.messagebox(time)
end

when I look at other examples I can't spot what I'm missing...

cheers for testing Garry, I chopped the bit out of a bigger plugin and missed re-defining sel for the new model

i.e. sel = Sketchup.active_model.selection

I updated the example code...

did it produce a model?

before fixing that, on the mac I get the new skp, then the sel error shows in RC...

i.e. it doesn't stop the new skp happening...

empty_selection works on PC and SU2014.

with_selection seems to work but not really. Perhaps because I can't find the 'copy:','newDocument:', and 'pasteInPlace:' .send_action options in the API.

However the 'newDocument:' option must work since I end up with an empty untitled model.

Also 'sel' needs to be passed to the with_selection method or changed to @sel.

that's good news, maybe I had another glitch in the full plugin...

they should all exist, but I may need to use the numeric values on a PC?
I recall, checking them all for Dan and thought PC's could use either...

you need to re-define sel or the @sel would refer to the original skp not the new one [on mac at least]...

I did update the code for that, did it still not work?

thanks for testing...

I had already made the 'sel' change in my copy of the code.

Like before, the file created on the desktop is the same for with_selection and empty_selection. With_selection leaves me with an empty Untitled model.

I get no errors output to the RC.

driven · 11 Feb 2016, 20:52

does finding the send actions work the same on a PC?

i.e. if I set 'copy' as a Shortcut, and then run Sketchup.get_shortcuts the wording returned can be used as a send_action string?

john

driven · 12 Feb 2016, 18:02

I removed the previous send_action()'s but added in Sketchup.send_action('makeGroup:') which should work on both platforms...

on a mac I get this, does it work the same on a PC?

Your undocumented:
Sketchup.send_action("makeGroup:")
doesn't work on [my] PC - BUT:
Sketchup.send_action(21182)
does work on [my] PC [but of course that doesn't work on MAC !]

But if you are working with creating a group from a Selection, then you can use the cross-platform API methods, thus:
group = Sketchup.active_model.active_entities.add_group( Sketchup.active_model.selection.to_a ); Sketchup.active_model.selection.add( group )
which mimics those other platform specific 'send_actions' on either OS...

I get a big red screen - that is all
My default template is set to mm with a precision of 0.001

driven · 12 Feb 2016, 19:01

cheers Tig, I may have gotten there eventually...

this works on the mac as suggested...

do I need to close the original on a PC for the new one to open with geometry and green background?

it's driving nuts as every version I've tried runs on a mac, and each one has been faster that the last...

# faster than collecting and deleting unwanted items...
def with_selection
	new_skp = File.expand_path("~/Desktop/john_test2.skp")
 	sel = Sketchup.active_model.selection
        group = Sketchup.active_model.active_entities.add_group( sel.to_a )
        Sketchup.active_model.selection.add( group ) if sel.length > 0
	ins = group.to_component
	defn = ins.definition
	# named only to check if it's been undone...
	defn.name = "Explode Me Later"
	defn.save_as(new_skp)
	# revert original
	3.times {Sketchup.undo}
	Sketchup.open_file(new_skp) # original stays open time depends on the selection size...
  # re-define for new skp...
	Sketchup.active_model.rendering_options['BackgroundColor'] = 'green'
end

@Garry, the template shouldn't matter...

I just can't figure out why you don't get the geometry...

This is just a tiny part of a working mac plugin that I'm now porting to PC...

on the mac it can grab 100 mixed items from a 1000 item file and cleanly add them to a new model...

one test file took 6 hrs to process and delete the 900 unwanted entities, where this take seconds...

On a PC an instance of SketchUp is opened for separate for each SKP.
On a MAC one instance of SketchUp opens all SKPs.
So on a PC, if you you use:
Sketchup.open_file("C:/users/tig/desktop/a.skp")
its opens that SKP file, BUT closes the current one !
But you could use:
UI.openURL("file:///#{full_path_to_skp}")
which, on a PC, will open the specified SKP in a new instance of SketchUp [and it'll probably work on a MAC, but then it'll be using the same SketchUp]...

it works exactly the same as open_file on a mac...

you can pass the new model to the next ruby method...

on a PC, I assume a new instance would need manual intervention to carry on to step 2 of any ruby script?

Are there ways around that?

I'm starting to see why 'component_edit_window' has so many observers...

...

on re-reading this and it may be all I need...

i.e. opens the new_skp [containing the selection] in the current ruby session...

Is that what happens?

keeping the original open isn't a requirement, in fact I'm wanting to preserve intact, and run my actual tool which is destructive on the copy/sub-set...

john

TIG · 13 Feb 2016, 17:17

Yes, opening a second SKP in the same SketchUp preserves the current Ruby settings from the first SKP.

If you open up a second SketchUp, then the first SKP's Ruby set up is potentially in accessible.
Of course, in the first SKP you could write some 'defaults' out to SketchUp [i.e. into the PC Registry], and read those back in, while inside the second SKP, but you then need to load/run some code ?

driven · 13 Feb 2016, 18:01

cheers Tig,

the plugin runs my 'selector' tool after new_skp has been cleaned up...

the 'selector' can be scaled, rotated or moved before running the cuts...

any solids remain solids afterwards...

I need a PC version to attract more testers...
