BUG_Shaded views in drawings missing colour (seemingly random)

[Matt126]

I am creating a colour-coded manufacture guide and unfortunately I am finding that some of my base views have a bug where the colour is either partially or entirely absent. I have tried flipping between shaded/line drawing settings, restarting fusion, opening on a different computer, exporting to see if it was just a graphics issue but it persists in all cases. 

Any suggestions on what I should try? Or is this a bug that I cannot fix.

It seems to be an issue.  Sometimes, the unexpected behavior is caused by sepcific modeling feaures or unqualified geometies in 3D design, because drawing needs to convert the 3D geometies as 2D in Drawing space. You can roll the history marker in the timeline of 3D design, and check which feature leads to this kind of issue in drawing. You can also share the dataset with us for investiagtion. Thanks
