Perform the following steps: •Create a rectangle: the size is the same as the size of the board; located some distance above the board (see Fig.1). Consider snapping points to the board corners and then changing the Z coordinate of the position • Select objects that represent the base for the mask, i.e. top substrate and traces (see Fig.2) •Using Ctrl key, select the rectangle as well •Go Modeler > Surface> Project Sheet, indicate desired thickness •For resulting object, change material to Solder Mask •Repeat for conformal coating creating a new rectangle and selecting solder mask as a base 3D object
