Thin Mesh is Clipping/Disappearing Partially No Matter How Close or Far

I have a Static Mesh imported via datasmith from Revit that is very thin and it starts clipping or disappearing at certain angles. it is strange because it happens when im very far away, very close. The picture above shows the revit file and how the mesh should be showing up and below is how it clips itself.

I ended up figuring out the problem is with normals, i exported from revit to 3dsmax unfied my normals then exported that into ue4 but all it did is flip the one sided to to the top instead of bottom so now i have a temporary fix where i jsut have two seperate meshes but if anyone could tell me how to fix the normals in datasmith i would still love to know!

Use Double-Sided material maybe?
