I tried to save my SketchUp file and when I reopened it the screen went blank. the file size still shows 155MB, so assuming the content is still available, why can’t I see it? the red, blue and green axis are also not visible. The measurements in the bottom right corner show a really big number (as shown in the attachment below) when I’ve been working in meters with a model size of 18m x 10m.

It is very likely that there is something at a great distance from the rest of the model. If you share the .skp file, we can help you figure out the cause and possibly fix it. It will be too big to upload directly, so please upload to DropBox or WE Transfer and share the link.

The camera was set to Parallel Projection and positioned in the middle of the solar system. There were 8 small borders placed long distance from the model reset that I removed. In the future, do your modeling with the camera set to Perspective and save the Parallel Projection for output.

There was also an incorrect use of labels. Edges and faces must be created AND LEFT untagged. You are also accumulating a lot of unused stuff in your model.

Getting rid of these things reduced the file size by 58%. There are still components in the model that could be simplified. I suggest you do that and keep your model clean to avoid problems in the future.

Here is the clean file. I’ve set the Face Style to Monochrome and turned off Outlines in the style to make the model easier to orbit and zoom. The textures are still there.

One additional note: you have a lot of exposed back faces on your model. If you plan to use a rendering application, it could cause you problems. For the following screenshots, I made the back faces purple.

Also, you haven’t used groups for the walls, floor, or roof of your building. It’s all loose geometry. You should use groups and components for the content you model.

Yeah. In fact, I’m still a student, so I’m probably not good at it. actually i still can’t access the file which opens blank on my laptop. while my other files still open fine.

Also, what do exposed back faces mean? I am very new to SketchUp.

I’m sorry. I should have deleted the scene you did because she was still screwed up. Try this file.

Faces in SketchUp have front and back. In a 3D object, ALL back faces must face the interior of the object. Only the front faces should be visible.

You should spend some time reviewing the instructional content at learn.sketchup.com
