AutoCAD2002 stuff, part 2

To all,

Apparently there was some misunderstanding. The ACADstuff.zip file
that I referred to in the initial posting on this topic is in the
Files section, not an attachment. I didn't make myself clear on that
before.

There was a question about the spherical addressing and cylindrical
addressing:

On spherical addressing the first number is a radial distance from the
start point, the second number is an angle in the XY plane, and the
the third number is an angle away from the XY plane (like an elevation
angle). Basically with spherical addressing you would end up with a
hollow sphere if you keep the same distance and kept changing all the
angles. I don't know if that is where the name came from but it fits.

On cylindrical addressing the first number is a radial distance (like
above), the second number is an angle in the XY plane (like above),
but the third number is a distance perpendicular from the XY plane
(height). If the first distance was kept the same and the angle and
the height were continuously altered you would end up with a hollow
cylinder.

I hope that clears everything up. If not, I'll try again.

Ivan
