Reference Plane Normal to Edge

You can sketch on a reference plane, created automatically, normal to an edge...To sketch on a reference plane normal to an edge...A reference plane normal to the selected edge is created at the end point of the edge closest to the selected area

Plane Properties PropertyManager

Controls the angle between the projection of the normal on the x-y plane and the X direction...Controls the angle between the normal and it's projection on the x-y plane

Arcs

SolidWorks infers from the pointer motion whether you want a tangent or normal arc...Moving the pointer in a normal direction creates a normal arc...between tangent and normal arcs by returning to the end point and moving away in a new direction
