the problem continues
Can you upload the problem part??
There are several reasons that this might be showing up as transparent, including a possible issue with your graphics card driver. If I can reproduce the issue on my machine, we can eliminate this as a probable cause.
When you get a chance, could you do a Pack and Go (File > Pack and Go) on your drawing to a .zip file and upload it to this forum?
Alternatively, we can check for a problem with the graphics card/driver by opening up SOLIDWORKS Rx on your machine and taking a look at the Diagnostics tab.
If it looks like the above or if it has a red X next to it, this is most likely the cause of the problem.
I hope this helps!
