The modeling strategies for Solidworks and LDraw are fundamentally different:
LDraw is based on triangle meshes, and Solidworks is based on constructive solid
geometry. Going from CSG to mesh is easy, but going the other way requires some
AI guesswork, and probably human input too.
LDraw does have various primitives which could help the converter do more than
spit out triangles, but I don't think anyone has written conversion software
that uses that data.
So for the time being, any geometry you bring in to Solidworks from LDraw,
regardless of the format, will just be a mesh of triangles. You may be able to
mate it, or use the vertices as reference points, but it won't be pretty with
edge lines turned on.

| Some further progress. It turns out that I was able to convert a .DAT file to .STL with LDView & import it into SolidWorks, but it further turned out that, once I'd imported an .STL file into SolidWorks, I couldn't do very much with it. I can't mate (...) (13 years ago, 25-Oct-11, to lugnet.cad)
