I am unsure which way would be the most consistent with other CAM applications.
From
my point of view, I feel comfortable drawing in the XY plane and I would have
thought
that the last-minute rotation by the Fixture class to re-orient the GCode to
the XZ
plane would be a reasonably intuitive way to work.
I am not a fan of adding the rotation only to the DXF import function. That
assumes
that people would rather use someone else's CAD application to draw and only use
Heeks to generate the CNC code. I believe the need to use other CAD programs is
diminishing with time.
I suppose another option would be to add a 'Re-Orient for Lathe' option to the
View
menu which would add a CoordinateSystem object. My understanding is that the
CoordinateSystem object re-orients the entered coordinates on input.
Part of the problem comes in the use of the keyin fields for coordinate values.
The
fact that one can enter exact values into a text field is one of HeeksCAD's
greatest
strengths for engineering drawing. It comes down to understanding how a lathe
worker
thinks of the coordinate system. i.e. when they enter exact values, are they
expecting to enter values in the X and Y fields or in the X and Z fields.
From my (milling) perspective, I would leave the graphics as they are in the XY
plane
and add the 'Re-Orient for Lathe' option to the Fixture object.
Sorry, I simply don't know how real people do this stuff. I'm just beginning
myself.Original comment by David.Ni...@gmail.com on 25 Aug 2009 at 2:54
