COONS and invisible edges

[Frank Beister]

Try the following example:

COONS  2,2,  64,

0,0,0.1,  0,1,0,
1,0,0,  1,1,0.1,

0,0,0.1,  1,0,0,
0,1,0,  1,1,0.1

ADDX 2

COONS  2,2,  8,

0,0,0.1,  0,1,0,
1,0,0,  1,1,0.1,

0,0,0.1,  1,0,0,
0,1,0,  1,1,0.1

This are two tiny COONS. The MASK (3rd parameter) has my focus. The manual tells us, that 4,8,16 and 32 control the visibility of the edges. In the first COONS command, this works quiet well, but in the second, when I do not show the segmenting lines (64) of the surface I can't switch of any of the edges. IMHO a misbehaviour, but as it is since min. AC 8.1 I could believe it is a feature. Any confirmations or corrections, what I am doing wrong?

Hello Frank,
You are right.
The COONS command does not work the way
the manual says it should work.
Even in AC 6.5 v4 it behaves as you describe.

Seems to be a Methusalem bug. As I understand the mail of GS it is now in the bugtracking list.
