Hello I new on this forum and this is my first model in sketchup free. I have drawn it to print on my Creality as gcode. the stl file looks ok but there are a lot of errors with the gcode file. I have read and searched for solutions and tried online tools without success. Can anyone help me with what i am doing wrong?

Share the .skp file with us. Are you using the web based free version of SketchUp?
Thanks for answering. Yes I m using the free web based version.
OK. Again, share the SketchUp model file with us instead of the .stl file.

Here it is.
OK. Your model isn’t ready for 3D printing.
In order to be viable for printing every edge must be shared by exactly two faces. In the Solid Inspector 2 panel, Stray Edges indicated edges without any faces, Surface Borders are holes in surfaces, basical only one face on the edge, and there are lots of internal faces.
Most of the fixing will require manual effort. If you were using the desktop version or SketchUp Go instead of the free version, Solid Inspector will be able to fix a little of it.
Thanks for your effort to help me.I understand that there are a lot of errors, I think the best is to draw again. However, I don’t understand why there are so many errors. Thanks again.
There errors come from the way you are doing the modeling. If you switch to the X-ray style you’ll be able to see the internal faces and many of the other problems. You need to make sure as you build the model up that you aren’t leaving internal faces and stray edges. Also, the spot where the corner of the chimney and that interior wall meet will be a problem. Either leave a gap or join them so there isn’t a zero-thickness edge running up the corner.
Starting over is most likely the best approach. Is this a model based on a real house or on a plan for a real house? I would suggest modeling at real world dimensions for the house and then scale it as needed to the desired size.
Think about the way the thing would be printed. Don’t draw in features until you have the model raised to the height at which they would start to appear on the print bed. And don’t leave edges between coplanar faces.
Here I’ve drawn the footprint of the entire house as one large face. I pulled the flor up to the height of the patio on the back before outlining the house, front porch, and the little step for the back door. Then I pulled the faces up furster. Notice the walls aren’t drawn in yet. The printer wouldn’t start printing them until after the stage on the right.
Is the x-ray style part of the free version? I understand that I have a lot to learn. I thought if it looks good as STL the model was fine! But its not that easy. I will start over again when I m in the mood for it. Anyway thanks for all your advices. Kind regards Otto
There is an Xray style in the supplied default styles.
The problem is, the .stl file will only be as good as the SketchUp model. The thing to be looking for is Entity Info showing the thing as a solid group or component. Obviously this isn’t a house but you can see how Entity Info indicates it’s a solid component.
I think that you can also take a “Lego” approach to modelling for printing as I understand that the model can be built out of solid component “blocks” that can also touch or overlap and the slicer will do the combining if all the parts are solids.

The “lego” approach seems to be a good idea too. I need to explore more about “solid component”
Yes. The LEGO approach can work well.
As I wrote before, a solid component is one in which every edge is shared by exactly two faces. So no stray edges, no holes in surfaces/missing faces, and no internal faces.Also make sure that the faces are correctly oriented. No exposed blue back faces in the 3D shape. The blue back faces are toward the print media, the which front faces toward air.
