Is possible configurate thickness of sheet metal?

That is a good question Eduardo. Seems like there should be a configuration drop down for that. I did find that if you double click on the Sheet-Metal feature in the Feature Manager you can click on the thickness dim (which is an equation) and from there you do get a configuration drop down. This worked for me for 3 configs with different thicknesses in my model.

Wanted to add. You can also add a design table and change things there also.

Edit:... Or in the equation manager.

Eduardo,

The best method I've found is to right click on the thickness dim, then select "Configure Dimension".  This will bring up the modify configurations dialog box from which you can change the thickness for any configuration.
