edit brush

Hi there
I'm using P&GD2013.
I draw with a wacom tablet and use the freehand brush tool in sketch mode with pressure enabled.
I want to edit the properties of the brush . The help pages are quite clear except that I can't access the dialog box because the 'edit brush' button is greyed out.
Thank you for any suggestions.

Unless you are using a custom brush or one of the novalty brushes the Edit Brush button is greyed out. I assume you are creating line drawings using the Freehand and Brush Tool "out of the box" and enabling Sketch Mode and Pressure Recording. You would need to create a custom brush to enable the Edit Brush feature.

Thank you... resolved
