Changes in 2015

driven

I just noticed in one of my plugins that loading a single small skp file (to use as a component definition) seems to take almost 1 second whereas the same code in SU 2014 loads the skp instantly.

I ran a variation of your script in v13 and v15 on my mac...

t = Time.now
f = Sketchup.find_support_file('candle.skp', 'Components')
d = Sketchup.active_model.definitions.load f
puts (Time.now - t) 
#  all in different sessions of SU
# v13 => 0.146086 , 0.037117, 0.022029
# v15 => 0.033036, 0.046043,  0.013811

test skp, not complex...

I was just guessing. The component browser DOES use the thumbnail if it is not set to display "List".

There used to be some time issues with thumbnails getting regenerated in the Component Browser.
Er.. or was that the Scene thumbnails ? It all blurs together.

t's a bit vague - what exactly doesn't work of these calls? Do you see Ruby's packing methods returning different results?
Is the DLL you are calling actually 64bit?
Does the function you are calling actually use ints - or are you using some other type that might be different on 64bit OS?

Yes dll is 64bit, I was passing double value as a pair of two ints. On c++ side it was double parameter, and call was passF.call(packedF[0],packedF[1]) on ruby side.

On a side note - the Win32API has been deprecated for a long time. It has many limitations and is easy to cause crashes with. The recommended now is using Fiddle.

That solves my problem, it does work now - thank you!
It is a pity that there is no fiddle on SU < 2014 (with old ruby),
and I need to use ancient Win32API.so method for backward compatibility.

Dan Rathbun

You can use DL which replaced Win32API.

I still try to support SU 6 and 7...

I don't.

Too many unfixed bugs, and they distro'd with Ruby 1.8.0 initial release, which is like 20 years old. (I wouldn't help anyone with 7 unless they'd replaced the Ruby DLL with a newer one, as I explained how to do in the "Ruby Resources" topic.)

Next year I'd say I will drop support for v8 and v2013, and be done with the old headaches that Ruby 1.8.x has, such as no unicode string support, etc.

Brighter3D

Maybe you are right...
For people doing renderings 2015 is first professional version (thanks to 64bit and possibility to use whole memory).
From the other side v8 is last true free version (according to the license)...

Do you know any recent statistics on SU versions usage?

I've never heard Google or Trimble release any official numbers.

Some plugin authors have collected data on what versions are running their plugin(s) but it's not global.

Perhaps the SCF Plugin Store has data ?

SU6 and SU7 is very low. I wouldn't be too worried about trying to keep support for these versions in new releases. It's like trying to make a website for IE6 and 7 these days...

There are some users still on SU8 - though it appear SU2013 users migrate faster. Not sure why that is. Maybe it's the Google => Trimble thing...

Personally I don't aim to support anything older than SU2014 any more - due to Ruby 2.0, standard lib and SU2014+ improvements. If my new releases will work on older it will be cause I didn't need to use the stdlib or any of the new SU2014+ features.

Thanks for looking into it. I tried your code on win32 and it loads the skp instantly. Great...but, plugins aren't installed in a sub-directory of the SketchUp installation directory anymore. Isn't it bad practice to put resources for a plugin in SketchUps installation directory instead of together with the code in the plugin directory?

I'm not seeing any performance regression - looks rather consistent on this end.. I'm not sure why you are seeing a difference on your system.

I have some data : http://thomashauchecorne.com/layers/analytics.php
But it's only about Layers Panel users (around 500 unique daily users)

Hi Thom, thanks for taking time to look at my code-problem.

I don't see big differences as well if I load components from the SketchUp Components sub-folder (see my post, two posts above your post).

Have you tried my original code (loading from root of C OR loading from the Sketchup plugins folder) and looked at the differences?

I tested your code and here are the results:

SketchUp Version: 15.0.9350

I still don't see any difference. Do you have a sample model to share?

Dan Rathbun

If a component has a classification assigned, the entire schema could be serialized into the skp file.

Upon loading the schema is loaded into the active model, correct TT ?

tt_su

Yup!

tt_su

Well, actually, I'm not sure what SU does when you import... Need to check that. But it could be that we load the schema.

@tt_su said:

I just did some tests with all kinds of code and you might be right it's my component files that are causing the problem. This one (see attachment) for instance takes 0.93 seconds to load in V15 while in V14 it takes 0.36

I'm puzzled...

edit:

the file in the attachment is 70kB in size. If I re-create it from scratch the file is 11Kb in size. Maybe there's something hidden/attributes that isn't purged using TIG's purge?

Ok - now I can reproduce this:

I'll forward this to the team. It looks to be related to the classifier system as after I removed the IFC schema and saved a new file:

The profiler will tell us exactly what it is. Thanks for the report.
