3D sketch planes

So far I am real happy that Solidworks is taking 3D sketch up a notch.
It is really fast and you can get a lot of design intent in one sketch.
I am finding that models rebuild more consistently and SWX doesnt seem
to crash as often. But..problems will arise

I am having issues with the 3D skech planes when I apply horizontal
relationships to spline endpoint control handles. Instead of the
handles becoming horizontal to the world, the grid becomes parallel to
the spline handle. In what world is that logical?

The workaround I have is to exit out of the 3D sketch plane by double
clicking, and then create a horizontal line that I then have to go back
into the spline sketch and make horizontal to. Blech!

Anyone figured out a better way?

 

Dale,
Thank you for explaining this to me. I dont fully understand the
underlying logic of 3D sketch planes then. This is probably because I
am thinking of the 3D sketch planes to be a more freeform version of
the regular construction planes. Can you please post some explanation
of how this localised coordinate system is used correctly?

 

Dale,
Thank you for your clear reply. I wonder why Solidworks chose not to
align the grid to the world by default. Thank you for telling me about
the Align Grid command. This will be useful in larning new ways to
sketch.
