If you have AutoCAD Map3D you might be able to publish the line types to
MapGuide. Gordon posted some info to his blog that might help you:

Also, search fdolinestyle. I haven't tried it myself
Sorry, there's nothing in Maestro that can automatically do this for you.
You will have to construct these line styles yourself through Symbol
Definition XML (or through the rather primitive Symbol Definition editor UI
that Maestro provides), and consume this Symbol Definition through your
Layer
