Revolve Effect - Object Appearance Error "CANT"
Windows 10 Home - 64bit.
Illustrator CC18. 22.1
When selecting Effects> Revolve on an object (a semi-circle) I get the error:
"The operation cannot be completed because of an unknown error. [CANT]"
Followed by another dialogue box:
"An error occurred while processing the appearance of an object."
What's going on here?
Same is happening to me.
