If i pick a model surface as my sketch plane, how do I set a different xy orientation rather than that defined by the world coordinate system - see attached image - I want the sketch xy to align with the surface as oriented in the image,
Cheers, Sean
I think what you might want is the Align tool. Look in "Tools, Sketch Tools, Align, Align Grid/Origin". It's way down toward the bottom of the Sketch Tools menu.
In this quick example I started a sketch on an angled (relative to the default planes) surface and reoriented it so that the origin is at the lower left vertex (red triad) and Y is aligned with the long edge (not the one highlighted in the screenshot). Note the blue part origin triad, to the rear, is no longer aligned with the sketch origin.
