Can a global variable be used in a design table? I am trying to set up
a design table for a set of cylinder pistons. The normal way to call
out the piston would be by the Bore of the cylinder it is in. The
actual OD of the piston would be .019" smaller. I have the part set up
with a global variable "Bore" = 5, then the dimension on the piston is
Bore-.019
Thanks,
Brian

Sure. Easiest way is to have a Bore cell in the table that holds the value.
Then the piston OD math is done in its own cell, referencing the Bore cell.

I've tried that, but I get an error that says "column heading "Bore"
contains an invalid feature name "Bore. Exiting desing table without
completing model update."

I'm talking to myself now. Put an empty column between the dimension
columns and the "Bore" column.

Or Give it the header "$comment".

Of course you can't put the Bore cell in the same row as the other
parameters, at least not in that form. You have several alternatives.
Assuming you also want Bore in the custom properties you can put it
there and reference it with a $PRP@Bore. You can also put $CUSTOM in
the row for parameter names and then put Bore in the first row of the
Design Table. Using the first row of a Design Table for human readable
labels is very handy, especially when using the Design Table as a chart
in a drawing. In that case hide the rows you don't want.
