When exporting to obj. some geometry is lost

SketchUp for Web

3D model of house.skp (1.1 MB)

home4.obj (50.5 KB)

I am trying to export as obj, however the windows and door details are lost during the process. Completely new to this software. Any ideas what might be happening? I tried orient faces several times, with no success.

When you export to OBJ. all the faces get automatically triangulated, you can solve it using the eraser tool or plugins but you require the pro version to be able to download them. Your house model doesn´t really have details on the doors or walls, they were just textures applied to flat faces when you export to obj you get the geometry and a folder with all the textures that were used on the skp model, the easiest solution is to export to other formats like collada or dwg/dxf to have the model with all the textures applied or apply again the textures from the folder that was created containing all that stuff. That´s why the obj file is lighter, it doesn´t contain any texture, its just the default one.

I used CleanUp3 to get rid of the extra lines with just by running the plugin, on the web version you must do it manually.

Edit: I just notice that all the textures can be found on the materials tray, so you don’t have to import them again, not sure if the free web version does that, I actually never used the web version, and strongly recommend everyone who uses sketchup for a living or if you have enough money to get a license and use it as a hobby, to get the pro version. It´s a lot much better, and you can add tools that increase your productivity a lot.

Thank you,

I installed the windows version and tried the CleanUp3 tool, but the details on the house were still lost during export

Make the details 3D.

What are you using the OBJ for?

I told you that those aren’t details, they’re textures applied on flat surfaces, if you want to see the details you must apply the textures again, which shouldn’t take you long because there are few materials, or model the details on the doors, windows, walls and every other part you want them to be seen. If you want to 3D print it’s necessary to model all those details and make the model a solid group or component.

For anyone that might be experiencing similar issue when trying to import obj file into XLights - make sure bioth .obj and .mtl files are in the same folder and with same file name. This was the issue for me.
