I followed the instructions in both the online help and the What's New document (they are different steps) and it doesn't seem to work either way. On the Sheet Metal tab of the custom material that I'm using, I created the table of thickness ranges and entered the bend deduction that I want for that thickness. When I check the box to use material sheet metal parameters, I get the message "There are no valid sheet metal parameters defined with the material". The ranges that I set up in the parameters have no gaps and I am sure that I am actually applying the custom material that I created the parameters in.
