Did they specify the "bug"?
They said, there is a bug. But specifically they didn't mentioned.
Below is the answer got from CAD tools technical person:
"Unfortunately, this is an Illustrator bug. When CADtools displays the Adobe color picker dialog, and you select a spot color, CADtools is never informed of that fact. CADtools is only given the equivalent color in RGB or CMYK depending upon the setting in the File->Document Color Mode menu. We have tried several workarounds, but have not been successful in finding an alternative solution. We have alerted Adobe to this bug and have also worked on some alternative color picking options, but they are not ready at this time. This is something that we hope to have a solution for in a future design, but at this time it has not been fixed."
Did you get any solution for the above.
No. I didn't follow up on this.
CADtools has since appeared in version 10 and maybe they have a workaround in it?
