Why not use
Model.save
?
http://code.google.com/apis/sketchup/docs/ourdoc/model.html#saveAnd I don't see how saving would free up the undo stack.
Seems to operate the same after a save...
I don't think saving has any effect - it's SketchUp that process existing geometry whenever new is added in order for auto-merge to work.

?I was under the impression that the API would not let use use that method to overwrite the current file. But I just tested it and yes, it does work.

And, your're correct again. (Maybe I made an assumption.) On PC we can clear the undo stack by saving, then asking for a new model, then reloading the old model. (The API does not have a method to close the active model, yet. So it may be a no go on Mac.)
Here's an updated example:
model = Sketchup.active_model entities = model.entities disable_ui = true save = true if save path = UI.savepanel("Save Model to","*.skp") if path.nil? save = false else path = File.expand_path(path) end end for n in 1..1000 do begin model.start_operation("Group#{n}",disable_ui) g = entities.add_group g.name = n.to_s point1 = Geom;;Point3d.new(n*10,0,0) c = g.entities.add_cpoint point1 g.explode rescue => e model.abort_operation puts("Error #<#{e.class.name}; #{e.message}>") puts(e.backtrace) else model.commit_operation # opt save model here if save Sketchup.active_model.save(path) Sketchup.file_new Sketchup.open_file(path) end end end

Is it explode that is slow ? Or adding group definitions ?
If making groups (and explode) is avoided, is it still as slow ?
Does turning off shadows and textures speed things up ?
-
There are issues with
model.save
.
It only saves by name, but not path obtained using File from model.path etc.
It does NOT save by the name of the current SKP, although it returns 'true'...
To test this make a simple SKP and save it as 'aaa.skp'.model=Sketchup.active_model Dir.pwd
if not where aaa.skp is located use
Dir.chdir(File.dirname(model.path))
now use
model.save("xxx.skp")
### it saves a copy as xxx.skpyou are still inside aaa.rb
model.save(File.basename(model.path))
### saves as itself - aaa.skp [supposedly, as it returns 'true' !]Now edit the SKP with a noticeable change, and repeat
model.save("xxx.skp") model.save(File.basename(model.path))
Exit without saving further...
xxx.skp WILL show the changes
aaa.skp will NOT show the changes, that it said were saved, BUT were not! -
@dan rathbun said:

Both. Adding geometry gets slower and slower in SU. When you explode you take the entities from one context and add it to another - so it suffers from the same slowdown of adding them.
@dan rathbun said:

It seems to be that SU processes all existing geometry when anything is added to a context.

.Thanks TIG... I knew you had expounded on this subject before.. and tried to get the Google team to fix this save BS.
Well, the example above at least DOES clear the undostack on PC...
which is why (ThomThom) I originally used the send_action for the PC menu's "Save" option. (Which does work.)

sigh the Ruby API makes my head ache all too often...

YUP. On PC,
Sketchup.send_action("save:")
returnsfalse
. I wonder what the standard action is for Mac ?Dittos.. on the API.

I wish that PolygonMesh had more features in the Ruby API. In the C++ SDK you can define more info when you create the mesh. Under the Ruby API you are more limited.
One example, you can retrieve the mesh of any geometry - from that you can get info on hidden/soft edges and UV mapping. But you cannot create a mesh with UV mapping or control hidden/smooth. That severely limits the usability of PolygonMesh as a method of creating geometry.
So either complex and very slow geometry creation, or simple and less slow creation.
Or use the C++ API - ...which require C++ knowledge...
Slower development...

You might try saving the model to a temp file, after each group. That should clear the undo stack.
The file must have a name other than "Untitled" or the save dialog will popup.Also use the
disable_ui
flag in an operation:model = Sketchup.active_model entities = model.entities disable_ui = true PC =( RUBY_PLATFORM =~ /(mswin|mingw)/ ? true ; false ) save = true for n in 1..1000 do begin model.start_operation("Group#{n}",disable_ui) g = entities.add_group g.name = n.to_s point1 = Geom;;Point3d.new(n*10,0,0) c = g.entities.add_cpoint point1 g.explode rescue model.abort_operation else model.commit_operation # opt save model here if save if PC Sketchup.send_action(57603) else # Mac Sketchup.send_action("saveDocument;") end end end end

BUT saveDocument simply saves the current SKP and leaves the undo stack alone.
IF we use
pwd=Dir.pwd Dir.chdir(File.dirname(model.path))
so we don't need to worry about full paths etc...
Then use
` skp=File.basename(model.path)
tmp=rand.to_s+File.basename(model.path)Sketchup.send_action("saveDocument:")
model.save(tmp)
Sketchup.open_file(tmp)
Sketchup.open_file(skp)`on completion tidy up
File.delete(tmp) if File.exist?(tmp) Dir.chdir(pwd)
it will cause the "undo stack" to empty !
BUT at the expense of the time delay of saving/opening/etc etc...
There seems no easy way to clear the "undo stack" otherwise... -
And we have no signs of "clearing the undo stack" will actually improve the performance of adding geometry, do we?

Was this a query? if so, the answer is yes, normally, but the way Dan has used it in the earlier snippets, the Dialog appears, but fails to change the windows name and the script then really does strange things in 'no mans land'
i.e. it's not 'Untitled Window', or your given name, just 'Sketchup'. The cursor pulses, the view disintegrates[holes appeared] then the whole computer freezes... repeatable, yes but I'll pass.
In my curiosity to learn some ruby, I cobbled together some additional test scripts and ran them on my mac.
Script 1: 1.52668809890747 and generates 2000 undo steps #### this is the original from this thread
Script 2: 0.175029039382935 and generates 1001 undo steps
Script:3: 0.419209957122803 and generates 2 undo steps
Script 4: 0.0664420127868652 and generates 2 undo steps #### this uses disable_ui and draws after the timer stops, so add 0.04 maybe...My scripts a probably really badly constructed, but they reliably return this similar timings... john

Well, John, you've proved that disable_ui is much faster that not.
But the topic is about that add_group and explode group is slow. Which you've also proved, of course, by testing the same entity generation within only 1 group and then exploding it AFTER the loop.
I only speculated that Sketchup's writing to the Undo stack (and Undo Log file,) might slow things down.
There is a registry entry on PC for "MaxUndo" (under the "Preferences" key,) which is set to 100 by default. There is no UI control to change this "on-the-fly." (And likely Sketchup would not see any change to the attribute while running.) But I wonder if setting it to 0 before startup would it disable the undo feature all together ?? (I don't know what it's called in the Mac plist.)
But, regardless, ThomThom believes that it's not the undo stack, but instead the way the app seems to resort the model database, during add groups and explodes.
What if all the temp groups, were first added to a master group (to separate them from the rest of the model, and then after the loop, the master group was exploded ?) -

I just tried this.. set "MaxUndo" to 0 before SU start.
The undo operations do NOT appear on the Edit menu.
Sketchup still writes to the undo log, but after each tool operation, it writes a "Commit(0)" line.
Changing the attribute back to 100 while Sketchup is running has no effect (as I suspected.) And Sketchup will rewrite it's "live" "MaxUndo" value of 0, back to the registry attribute. So you must change it back to whatever limit you wish, while Sketchup is closed, in order to turn the Undo feature back on.
-
Also, note. When "MaxUndo" is 0, calling
Sketchup.send_action("editUndo:")
still returnstrue
, but nothing happens. (At least it does not BugSplat, which I did fear.) -

It appears to here, I can see a cursor image refresh as each group is created@unknownuser said:

macSU .plist <key>SketchUp.Preferences.MaxUndo</key><string>100</string>
I think if you write to, then touch, then read SU uses the update, but I need to check if it works for SU prefs, it does for 'user' ruby ones.@unknownuser said:

making a 1000 groups adds 2000 undoes, which is much slower than putting it in the langhandler (which I thought would have a big overhead) with only 1 undo +1 for the explode outside.
@unknownuser said:What if all the temp groups, were first added to a master group (to separate them from the rest of the model, and then after the loop, the master group was exploded ?)
I'll try and work out a script to do a test, unless you want to...
I wasn't really doing this to post back, it's just an exercise in me understanding SU ruby (on mac), but the results seemed to be relevant to the OP's mac/group inquiry. Yell at me if it's not.

(At least it does not BugSplat, which I did fear.)One thing I have found when modifying NIB files, is you often need to save, open/close SU then re-save 'manual' preference list changes, to clear SU's cache. Not sure if it's the same with coded writes and maybe it's only the SU ones that are cached?
