The mentioned text (PVP2016-63075) indicates that "minor components such as nozzles..." shall not limit the MACA. Is this true in reality? For those who have determined the MACA for a vessel, did you ignore the nozzles?
@CorBlimeyLimey, thank you for your suggestions. As far as I can tell, my Nvidia Quadro 410 is an approved graphics card and I have changed the SOLIDWORKS background back to the bleached default. Still, the arrows do not appear.
That being said, I do not believe the graphics card is the issue...
SOLIDWORKS 2017 includes the dynamic reference visualization feature (http://help.solidworks.com/2017/English/WhatsNew/c_dynamic_reference_visualization.htm).
Unfortunately, I am unable to see these arrows regardless of being enabled in the design tree.
I thought the file was bugged but...
With the "Cylinder Dimensions" dialog open, you may consider enabling the "Details >>" tab at the bottom. This will reveal thickness requirements due to internal "t(int)" or external "t(ext)" pressure.
@Mark1arm,
I believe your question is addressed in General Note (e) for table 1A in II-D.
"(e) Stress values for -20°F to 100°F are applicable for colder temperatures when the toughness requirements of Section III,VIII, or XII are met."
