Import stl impossible

pilou

Convert it in OBJ format with the free MeshLab
and see if you obtain a better result with OBJ import inside SU by TIG

fpallut

Merci de ton aide.
L'import obj fonctionne parfaitement, l'affichage de l'import obj est instantanné dans sketchup. Cependant je préférerai trouver un plugin import stl qui fonctionne. La plupart des fichiers proposées sur Thingiverse pour imprimante 3D sont au format stl et je voudrais faire au plus simple pour que mes élèves puissent travailler sur ces modèles, donc éviter d'utiliser un autre logiciel.
C'est quand même bizarre qu'aucun des plugins import stl que j'ai essayé pour le moment ne fonctione ! (su2stl, stl4su, cadspan, jf_stl_importer)
Combien de temps peut prendre l'import d'un stl de 1 Mo dans sketchup ? Est-ce très long ?
Merci de vos réponses

Try MOI3D. It exports skp.

@Fpallut (en anglais dans le texte
Can you post an example of one file STL for some tests on old versions of SU!

Maybe there are different version of STL files ?

PS Moi exports STL and SKP format but not Import them!
But you can make this tricky thing!

Free program following permit to convert OBJ format in 3dm format (nurbs) by Michael Gibson!
(creator of Moi)
http://moi3d.com/download/Obj23dmWireframe.zip
(only structures of Edges)
But as you can choise to have each faces closed as a closed polyline you cane easily in 3third nurbs 3D party make faces! (In Moi for example)

Don't take some Zbrush OBJ files of millions of polygones!
Make some big decimateion before!

On a maintenant la possibilité (ou non au choix) de "fermer" automatiquement toutes faces "planes" d'un fichier OBJ pour le transformer en format 3DM!
http://moi3d.com/download/Obj23dmWireframe.zip

Vous pouvez choisir de créer une seule ligne pour chaque arête sans doublons comme avant,
ou vous pouvez désormais également choisir de créer une courbe polyligne fermée pour chaque face.

Ce qui fait que l'on peut importer tout objet format OBJ dans Moi!
Une fois importé
Il suffit de sélectionner toutes les facettes et d'utiliser la Fonction Construire / Plan
Il serait bon à cette étape de supprimer les courbes des facettes car elles font doublon avec les facettes planes créées

Et Editer / Unit pour en faire un volume entier si les facettes en composent un!

Pilou,

Thamks for your response and test

Hi,
I try to import stl files in sketchup.Try with many plugins but no results ! binary or ascii files, no reults !
I'm working with seven 64 and sketchup 8 free
Can you explain me how should I do to success ?

Thank you in advance

françois

If you cannot make it work with this STL plugin (http://extensions.sketchup.com/en/content/sketchup-stl), can you please post the STL file for inspection?

GitHub Repository: https://github.com/SketchUp/sketchup-stl

Here is one file that I cannot import :

Thank you for your advices

Using the plugin I linked to it imported fine without any problems.

Are you using that plugin, or some other variant?

fpallut

I try on a seven 32 machine and... it works !
I do exactly the same with my seven 64 machine and it does not work. I cannot import the file I've uploaded on the forum.
SO why does it not work with seven 64 ?

tt_su

I use Windows 7 64bit. It's working fine.

I'm guessing it's either not installed correctly or might not be using the latest version.

Have you ensured you have the latest version? How did you install it?

If you open the Ruby Console (Under Windows > Ruby Console) do you see any errors when you try to use the plugin?

TIG

Do you have FULL security permissions set for the Plugins folder for ALL listed ?
That might be the difference and so the 64bit limited Plugins folder looks OK but Windows ahs put somethings into a VirtualStore ??

fpallut

I verify security permissions set to ALL for users.
Ruby console says :
No such file or directory - C:\Users\François\Dropbox\Imprimante 3D replicator2\Modeles pour imprimantes 3D\Camera_Phone_Stand\Camera_Phone_Stand\UpperHolder.stl

C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/sketchup-stl/importer.rb:52:in `load_file'
And then nothing appears, the file is not import
??

At last we have the culprit...
" François"
Used in the file-path contains a 'non-ASCII character' [ ç].
In the current version of Ruby as ported with PC SketchUp this will cause unexpected failures in several File related processes...
We can but hope that the next SketchUp version will address this long complained about issue.

For all SketchUp-Ruby related processing, use file-paths that do not include any such 'accented characters', and you should find the tools will then work just fine !

tt_su

Ah, the old Unicode issue with Ruby. I'm filing an issue in the STL project to provide a message when this occurs. Thanks.

pilou

accents are a damnation for us, poor Frenchies!

tt_su

Ain't easy for us 'weegies either.

fpallut

This subject can be closed.
On the same machine, I create an account without ç and no problem the import works perfectly.
Thank you for all
