The junction of a curved and straight moulding, or of two curved mouldings of dissimilar sweep or direction, is not in a straight line, therefore either the profile of one must be altered or the mitre line itself must be curved. Obviously the latter method is always simpler and the drawing below shows the procedure. Arbitrary lines are drawn either from the salient points of the profile 353A or, if the moulding is composed of one large member only, at any convenient spacings, and the curve is then drawn through the points of intersection.
