[...] having some issues with importing blend and obj files.
Hi James!
Your .blend model was created with which version of Blender? Could you send it to me via PM please?

Here my workflow.
Construction on Sketchup 17. Export as collada file.
Import to 3DCoat for texturing. Export as obj file.
Import to Model Converter X for checking and file conversion. Export as obj file.I do check the polygons in every step and they are the same in every step. Pic1 shows the correct wireframe so far.
Import to Sketchup with "Universal Importer Plugin". Now the wireframe is not as it was in all the steps ahead. Some of the edges are missing. I´m not using any polygon reduction. Pic2 shows the result after the import.
My question to you is only, why the imported wireframe is not the same as it was in all the other steps ahead. Because the wireframe is broken in some area, the texture does´nt fit any more.
For an additional explanation. The workfrlow may seam strange and all can be done with different software solutions much easier. You are all right, but this is my workflow I´m used to it.
Hi Walter,
I don't want to criticize your workflow, but try to have less conversion steps as this can cause problems.
Hello Pilou 
It should be compatible with SketchUp 2017+.
The PBR 2.x plugin for SketchUp could render the atmosphere with volumetric clouds in real-time.

Hi Samuel,
Have downloadeed the latest version along with sketchup pro 2023 for mac, but every time i try to import a model fbx or obj im getting the errow shown.
Any advise
Universal Importer Error: Command failed: cd "/Users/davidott/Downloads/Test" && "/Users/davidott/Library/Application Support/SketchUp 2023/SketchUp/Plugins/universal_importer/Applications/Assimp/Mac/assimp" export "uir-source.3ds" "uir-inter.obj" -tri
Hi David,
In this situation, the error message does not provide enough details. Maybe your macOS is not allowed to run Assimp executable?

Dear samuel_t, I just installed your plugin, but I can't import the step file, I get this message. At the same time, a duplicate of it with a different name is created in the folder with this file. You can help me?
Dear Roman,
Unfortunately, compatibility with the STEP format is low.
1.2.3 version doesn't display anymore the "Source dir of model to import is not writable" error message.

Thanks for the technical details. I will solve this problem as soon as possible.

Does not want to export FBX and other files. Reinstalling doesn't help
Try importing a 3D model stored in a folder to which you have write access.

Universal Importer V1.2.2 does not import any stl file. Universal Import Error: No such file or directory @ rb_sysopen - C:/3D/bottle-opener/uir-inter.mtl

Please help (Sketchup Make 2017, Windows 10)

Could you please send me this STL file via Dropbox, for example?

Could you also include Revit .RVT import with textures as well?????
There is little chance that the RVT (Revit) format will ever be supported by the Universal Importer plugin.
However, there is a paid add-in for Revit that allows you to export a Revit model and its textures to SketchUp.
1.2.2 version deletes temporary hard links and temporary files possibly left after an import fail or a polygon reduction fail.

Here's a simple cube saved in Blender 3.5 that fails to import...
[attachment=0:hhrjer15]<!-- ia0 -->cube.zip<!-- ia0 -->[/attachment:hhrjer15]
Indeed Rich, Universal Importer passes Blender 3.4.1 cube test but not Blender 3.5.0 one.
Thanks for your report 
Hello, I am pleased to announce the availability of Universal Importer 1.2.0! Here are the changes brought by this new version:
Improvements
Imports are faster due to the fact that the plugin now uses (as much as possible) temporary hard links instead of classic temporary files. This also allows to monopolize less disk space during the import process.
I refactored some of the plugin code to make it cleaner, I hope so 
Bugfixes
Polygon reduction from the toolbar was not working anymore (or not for all models). The number of faces before and after reduction was about equal, very far from the target... It's fixed!
Thanks to the great work of the Assimp contributors, you should no longer get the error:
"End of file or read limit was reached", when importing a .ter file (Terragen).
"Constructing BlenderDNA Structure encountered an error", when importing a .blend file. By the way, the files created with Blender 3 are now importable provided you:
The bug of imported materials with zero opacity is fixed. Thanks to JDD for reporting this bug.
It is now possible to load an .obj file that references an empty material library ("mtllib"). Thanks to Jérôme Tas for reporting this case.
A heavy model (e.g. more than 400 000 triangles) can lose triangles once imported into SketchUp with Universal Importer. This problem has not disappeared yet but seems less present... Thanks to Didier Bur for reporting this problem.
Translations
I took the liberty of including a Japanese translation of Universal Importer, found on the PC-Trace blog. If you are the administrator of this blog, I invite you to contact me to become the official Japanese translator of the plugin.
If Universal Importer is not available in your native language, feel free to contact me to become its official translator

Still getting errors even on simple cube mesh. No materials, no modifiers and no external files linked or appended to .blend
Hi Rich,
Thanks for your quick bug reports.
Does Universal Importer v1.21 allow you to import other formats than .blend?
Can you please attach this very simple .blend file that refuses to be imported?
1.2.1 version handles the case when you import a model from a non-system disk partition such as "D:".

This is on Blender 3.2.1 files. Even a simple cube fails
Hello Rich,
This error is fixed in upcoming Universal Importer version! In fact, even current Blender version (3.4.1) will be somewhat supported. More news on this topic very soon
