The following is a method of getting the section of mouldings meeting in an obtuse angle when the mitre is square to one of them. First set out the obtuse angle CAD, and mitre line A B; then draw the section of the main moulding as shown at E. Next draw line D H at right angles to A D; then from C G draw a number of ordinates parallel toC A, meeting AB as shown, and from where these meet AB draw the second series meeting D H as shown. Then by pricking off the distance of each ordinate from D H the same as its corresponding ordinate from CG, a number of points will be obtained through which the section of the moulding can be drawn as shown at F.
