[Plugin] OBJexporter v3.0 20130131

Looks like vertex merging was added in the latest version. Anyone know if we can find older versions?

2.9 20130130 Merging of shared vertices is now optional, as it slows processing
for larger models.

Thanks for the reply. While I have you here, is vertex welding something that SketchUp does internally? I am having issues where I need to load an OBJ and then export the OBJ without any modification to the vertices at all. No optimizations for any reason as I render using texture arrays and need the unique vertices to set the texture index. I wrote a post in the main forum but nobody has replied yet. Figured I would ask.

Thanks

I don't believe that is internal to SU. You might try using a different export format (like .dwg or .3ds format) and then convert to obj in a different app (like Blender or FreeCAD)

Where i can find the OBJexporter v3.0 20130131?? i can't find it anywhere

Please learn to do a bit more directed searching...

There are hundreds of useful tools in the SketchUcation PluginStore...
So try this: https://sketchucation.com/pluginstore?pln=OBJexporter

Note that the very first post in this thread even includes a link to that very page !

i.e. the large button near the end of the post saying "Download"...

xo i was trying to download it to OBJ, but everytime export it, it only export a third of the components. is there a max file? and can i fix this problem, so i can export it all in one go.

TIG

There's no limit, but the more faces the more time it takes.
How big is the file ?

When you say it's missing out faces, can you explain fully.
Are there faces that are simply not there ?
Or are there faces with no materials ?
One possibility is that your model has reversed faces with textures on their backs, these will not show in most render apps. Either getting displayed as black, white or 100%-transparent faces.

To see if there are reversed faces use View > Monochrome, with a Style that has a distinctly colored back-face color. If you see any back-faces, then they won't render properly.

It's best to ensure faces are properly oriented as you model using Monochrome and the context-menu > Reverse...

Luckily there are tools to try and fix such issues for you...
Try this one of mine... https://sketchucation.com/pluginstore?pln=FixReversedFaceMaterials
Please read its usage notes...

I have been trying this exporter, and it works great, expect on components or groups that are mirrored or flipped. The normals are reversed. I have made sure that all the faces/normals are facing the correct way, before using this. They are. Any ideas?

This Exporter is quite old and it is no longer being updated.
However, a work around for your reversed normals in mirrored objects would be to use the Outliner to Select all of those Groups/Component-Instances and Explode them, then do the Export, then Undo the Explode ?

I have never heard of the outliner tool. Thank you. Yes, I could, and have, exploded the entire model, before using this script to export it. I was trying to avoid doing it. Thank you for responding.

I know this thread is quite old, but I'm fairly new to Sketchup, at least as far as doing something practical with it. I was told this plug in will allow me to export my Sketchup models to 3ds Max (which I don't even know how to use yet). The idea being I can then texture them nicely.

Now I have downloaded the OBJexporter which is a .rbz file. How do I install that into the Sketchup plug ins?

Are you actually using SketchUp 8 as indicated in your profile? The answer to your question depends on the version.

Mim86

Yes I am, it is 8.0.14346.0
