[Plugin] OBJexporter v3.0 20130131

TIG

As I have no way of knowing what it is you are trying to do then I don't have the feintest idea what's up.
My exported OBJ files have proved to be compatible with all of the standard apps that can import such files.
Have you tried exporting a simple box and seeing if that works...

Bugsplats during the export are very rare, if the SKP is large with complex geometry etc it can take a while to complete; so don't confuse a white-out with a 'crash'!
When Sketchup is doing intensive calculations it sometimes looses its screen focus and says it's 'unresponsive'.
However, it is still beavering away in the background writing the OBJ data etc.
Leave it alone until it's completed its tasks.
If you run it with the Ruby Console open do you get any error messages ?

If you still have issues and it's not just your impatience that's aborting things... then can you post [or PM] a sample of a SKP that is failing, so I can look at it...

For example do you have anything peculiar about your SKP files?
Like very small geometry, or very large geometry, edges and no faces, oddly grouped geometry, oddly layered faces/edges etc etc... ???

Thank You, Thank You, Thank You! Been going nuts trying to find something to do this and this is PERFECT. Have a great day!

Hi! I'd like to thank TIG once again for this truly awesome plugin as well as all the subsequent updates.
I frequently recommend this plugin for people who are new to SketchUp, showing them that their modeling efforts can be used in other programs besides SketchUp.
A lot of people tend to believe that SketchUp is very limited, has no export options for the free version and are not aware of all the amazing plugins that extend SU's capabilities and give it greater power.
I was just writing a short "How to" for people who wish to use their models in Poser/DAZ studio, but it occurred to me that while I giving instructions on how to install a ruby script such as "OBJexporter" I was not sure if there were any other plugins that needed to be installed for OBJexporter to work properly... I have quite a few and the thought came to me when I was describing the progress bar and "Model exported in X# of seconds" features... so I figured I'd ask-

Does OBJexporter require any other plugins such as Progressbar.rb to function properly?

Thats probably a pretty stupid question, but before I tell someone how something works, I figured I should probably include any relevant additional information.

Thanks in advance for any information any of you can provide!

TIG

My OBJexporter code is 'self-contained'.
It only 'requires' sketchup.rb, and that is installed by SketchUp itself in the Tools folder...
The progress reporting etc is built-in to my code and needs no 3rd party helpers...

Thank you once again!

Hi, I press the OBJexporter button... then it ask to "convert all to png?".
Wether I press Yes or No, I get nothing, it just close. Please help!

TIG

Run with the Ruby Console open: this will report progress etc...
Tell us any error messages.
If you are working with a Selection it must contain Faces...

Are no files [OBJ/MTL] or textures' folder made at all ?
Do you have permissions to make files in the destination folder etc??

Thanks TIG for this plugin.

It seems that groups are not exported with their SKP names.
For example if my group is named "Cylinder" the exported group name is "test-GRP-Cylinder-566-Color_A01" which is a bit annoying because I have to rename all my groups after exporting.

Also if I make a group with name "Level1" that contains 2 groups with names "Level2_A" and "Level2_B" without any other geometry, the group "Level1" won't export in the OBJ file.
Therefore ther is only one level of hierarchy exported...
Can it be a limitation of the OBJ format by itself ?

Cheers !

The 'grouping' in the OBJexporter file format is effectively 'by material'.
Each facet has a assigned a group based on:

ModelName-ContainerType-Name-ID-MaterialName

As Group names are no unique and Components can have multiple instances the ID is needed.

So for your:

test-GRP-Cylinder-566-Color_A01

Working right to left the geometry is thus...

MaterialName = Color_A01 [the Material's name, adjusted so its characters are OBJ compliant]
ID = 566 [assigned by SketchUp for the container's definition, during that session]
Name = Cylinder [the Container's name, adjusted so its characters are OBJ compliant]
ContainerType = GRP [Group]
ModelName = test [the Model's name, adjusted so its characters are OBJ compliant]

Note that if you had say 'Black' end facets then they would grouped separately as:

test-GRP-Cylinder-566-**Black**

Thanks TIG for such a complete explanation !

But I still think it would be very useful if the groups could be exported with just their names as we can see them in the Outliner.
Then if the name isn't unique the exporter could automatically add a "_1", "_2", "_3", etc. at the end of it (for example).
I don't know if you see the need for it but when I export a scene with a lot of groups it takes me a lot of time to rename them back manually with the name I originally gave them in SU.

Maybe it could be an export option ?
I understand it would be more work on your side as the exporter doesn't have any "export option" window...

Still it's a good plugin that I use all the time ! Thanks !

I have the same problem
Everything is ok and i gave a normal name to may new file. I even ended it with .obj ...
And I have administrator rights...
that´s what loks like in the Ruby console:
OBJExporter:
C:/Users/André/Desktop/Untitled.obj
Error: #<Errno::ENOENT: No such file or directory - C:\Users\André\Desktop/Untitled.obj>

May be you should avoid the "é" in your path.
I suggest you use only UTF8 characters.

Hello,

I downloaded the plugin. Installed it in the plugin folder of sketchup8 but when I start the program I can't find it.
Does anyone know what to do ?

thanks

Ibo

TIG

Under the File menu - like many other Exporters ?
and like it says in the instructions...

Help.

I put the RB file in the SU 2013 (free) Plug-Ins folder. I restarted but still only have the option to export as DAE or Google Earth. Please advise.

Thanks so much for your help!
