Due to Drawing workbench and additional Drawing Dimensioning module being in development for years they indeed do offer production ready solution. The idea of combining and providing them both side by side with TechDraw in FreeCAD 0.17 was likely born because of that.
There is much to be said about Drawing workbench. For example in FreeCAD 0.16 it has rather severe issues related to drawing templates support. This was fixed once FreeCAD 0.17 development cycle already started. And although Drawing Dimensioning module added parametric support for dimensions in one of the last commits it broke support for Draft Drawing
geometry. Therefore there is a trade-off involved. Do you want parametric dimensions (that is they are updated once the underlying model geometry changes) or do you want support for dimensioning Draft Drawing geometry. If you would like to add dimensions to Draft Drawing geometry you need to use slightly older version of Drawing Dimensioning module and not the latest one. Now as Yorik suggested you can have control over Draft Drawing geometry hidden lines:
But as for Drawing workbench made views you have no control over the hidden line. I once investigated this and the solution would be to take scale into consideration:
But as that didn't happen you can do that in post-processing phase yourself. That is do as much as you can in FreeCAD. Export the drawing to SVG. Select and change the hidden line "pattern" in Inkscape.
