Importing STL into Sketchup

Recommended Posts

Hi everyone,


I got a question regarding importing STL file, specifically into Sketchup.


We want to print a 3 story house (every floor seperatly). I got all the floors as an STL file from the Architect.

To print the floors we need to split them in segments as the scale will be 1:50. 


Only the STL files show up as this:


Its a real work to remove all the extra lines that are not needed (as STL creates triangles out of every surface).


Is there another way to import an STL into sketchup without all the extra lines?


Thanks in advance.

@XYZDesignPro Sketchup can read and export STL files, but their stl files are notoriously messy. I've had more than one customer submit stl files from sketchup that needed to be corrected or outright redone given how badly the model looked once put in CURA: missing layers and trouble telling what is inside and outside where two mesh would meet resulting in empty spots instead of walls where the biggest troubles I've had with STL from Sketchup.


@Florisvh It would indeed be easier to ask the architect for the files at the right format so you can print them, or maybe if he could send you the various elements as separate files so you can print them one by one?


That being said, the extra lines shouldn't affect the quality of the print or prevent you from cutting the model in parts. They're a visual annoyance, that's all.


I'd also suggest suing a real 3D modeling software like Blender to make proper cuts of your model. You can find many tutorials online explaining how to use the tools available in Blender for cutting complex mesh like yours in several pieces without completely destroying it.

I will look into Blender, thanks for the tip:).

I found a cleanup tool for Sketchup (Clean-up 3), which cleaned every line that is not needed in seconds, that helped alot.


Regarding to exporting from sketchup to Cura, what do u recommend file wise? I'm using .obj at this point.

i'm asking this because we are trying to print with 2 colors but this doesnt go well. The second color just screws up in the first few layers.

All settings are correct, using PLA we use 2 x 0.4mm AA nozzles (both cleaned) and the printer is callibrated. using the second nozzle on the first and the first on the second gives the same result.


Off topic but maby u have an answer to that aswell:).

I would recommend ditching Sketchup and using something else, like Blender. ? Blender is a bit harder to learn and use than Sketchup, but the results are so much better. I've designed a few things in Blender, and printed more things designed in Blender then exported as STL into CURA with no troubles with the models.


I say Blender because it is free, but there are many alternatives out there, most of them requiring to be bought though.


As for your other problem, I'm' not quite sure. If that's supposed to be a wall made with the second color, I'd guess that this is massive underextrusion, since I don't see the dreaded spaghetti all around the model. Have you checked that the settings for both extruders are the same? Also checked your feeders or the spool to make sure that the filament is moving correctly?


You should open a dedicated subject for that problem, there are people with far more knowledge about such problems that could give you a better answer and solution.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
