Hi @travis.designer.vn
Try running MergeAllEdges on the surfaces and then exporting as STP. Does that come in any better?

Edit: There will of course always be edge breaks where the surface is split and at the tiny notches on the upper edge - if you want to avoid that, you have to build the entire surface as one and loose the notches.
