I guess I'm thinking about this differently.  It's not that the

can place a 1 x 6 technic plate with rounded ends on any single stud at
some funcky angles) It's the combination of the contraints imposed by at
least 3 studs in a non-linear arangement that results in the 90 degree
"snaps" in that plane. Just like 2 studs limits one to 180 degree snaps.
  It's even worse than that. It's the number of studs that are actually
being used, not count of stud primitive on the element, that determines
how things behave.  Try putting some 1x1 round plates (dots) in between
some bricks and you'll see what I mean.  With just 1 dot you can orient
the 2xN bricks at any angle.  We need to allow for things like that so
any stud primitive, where ever it is used, should always allow aribrary
angles...

I have tried to accommodate these sorts of behaviours in two ways:
Priority and override.

If two parts have different behaviours like a "dot" and a "Brick" the one that
is moved to form the connection is the one that takes priority. If you move a
dot connected to a plate with the dot as the primary selection (Pink highlights
in glide) then the connection angles are taken from the dot. Which is freely
rotating. Thus allowing lots of angles between the brick and plate.

Override is much simpler. The maximum and minimum rotations are ignored, as are
the locking angles. The click simply rotates freely about its axis. This is to
allow for more creative use of brick arrangements.

I believe clicking should be an aid to creating LDraw models with out being
restrictive.

Hopefully this should be possible.

The real test is going to be what people think of it once the first version of
GLIDE with clicking is released.

I should point out that priority and override are features of GLIDE and are not explicitly specified in the format. (20 years ago, 23-Jun-04, to lugnet.cad, lugnet.cad.dev.lcd, lugnet.cad.dat.parts)
