CATIA global parameter, rookie question

I need to use a diameter value directly (not radius) in design table. But the parameter I'm linking to is radius & I can't find a way to change it to diameter, or make diameter the parameter for a circle. So I put diameter values in my design table (in Excel) & it translates into radius in my model. Can anyone please help?

EMON,

CATIA parameters are based on radius only, not diameters.

Make a parameter for the Radius in your Design Table. In Excel, you can add a seperate column for diameter, and do the math to calculate the radius from it.
