Jeff, I think you misunderstood Ty. He was indicating that the script only works with SketchUp 2018.
If you’ve installed SketchUp correctly, the things to do are:
- Try updating the Intel graphics drivers.
If that doesn’t help…
Roll back the driver to an earlier version when it did work.
Get a graphics card that is reliable and up to the job. Intel Graphics HD GPUs are well-known to be lacking in proper OpenGL support. Of course upgrading to a good card (Nvidia) may not be possible without replacing the entire computer. Such is the case with most notebook computers.
Go back to an older version of SketchUp, such as 2016, that allows you to turn off Hardware Acceleration and dump rendering duties back on the CPU.
