Hi @archichan2
First i would change the detail level to fine and see if something changes.
Is it a model in place or a family?
Can you share pic with properties of the beams?
Check:
-Struct Framing visible in VG of 3D View
-Worksets ( what workset is framing on, is workset visible in 3D View?)
-Phases/Phase Filters of 3d view
-Filters in VG of 3D View
-Is an object such as a floor or roof hiding the framing?
-Is Structural framing hidden in view ( Reveal Hidden Elements )
The Structural Framing families provided with Revit are set to show as stick symbols (aka lines) when your Detail Level is set to Coarse. Change the Detail Level to Medium or Fine and you should have no problem.

Yep--I knew that! That was also already mentioned in the 1st reply to the OP.
