Re: [CAD_CAM_EDM_DRO] Re: How to go from 2.5 D to real 3 D ??

Hi All:

Rab's got a good point. Arc's really don't offer any real advantage over
linear line segments other than file size and memory requirements for the
controller. For some this advantage is necessary, for others it is not. In
Fact, it would make creating a software controller somewhat easier is all
moves were linear line segments. Even EMC has a problem calculating
velocities and acceleration constants in an arc routines if you look at the
code, where those calculations are trivial in linear segement moves. Since
the real experts at resolution of output and such are the CAD guys , (like
Fred), I must say I'd love it if all moves were linear segments and were
therefore left in the realm of the Cad/Cam program itself. . Size of a file
is rapidly becoming somewhat irrelevant due to mass storage devices being
larger, but obviously, some folks will require smaller size files for some
time.

Just a thought,
