Only vertical section planes invisible in layout

Hi,
I can’t figure out the next puzzle. I hope you can help me.
I have horizontal and vertical section planes in my model. If I export the model to layout the lines of the horizontal section planes and their icons are visible, but only if I view the model from the side. If I look from the top all lines and icons (except for the grey areas of the horizontal section planes) disappear. I have saved the scene and the style in sketchup, the way I would like to see it in layout. I have reloaded and relinked the model. Also tried hiding the horizontal planes, nothing seems to help. If I orbit the model in layout the horizontal section planes and the icons reappear the vertical ones are still invisible.
Anyone any idea what to do?
Thank you,
JR

That is still a problem in the latest versions of SketchUp. One of the developers has a potential solution, so hopefully it will get fixed some day.

For now, if you put the objects and the section planes into a group, they should remain visible in SketchUp and LayOut.

Hi Colin,
Thank you, this works!
Another conundrum popped up. I’ll make a new topic.
Kind Regards,
JR
