By taking the side view of the orthographic and scale, shear, rotate (SSR) it onto the Isometricplane you can figure out the thickness of the guitar body.
比例缩放，倾斜，旋转(SSR)。并且在等角平面上，你可以利用这个侧面视图计算出吉他琴身的厚度。

This courseware is used for finding the position of the endpoint of two intersecting triangles and drawing the surfaces, the isometric projection of the intersecting line and three-plane projection.
两平面交线课件主要功能用于求解各种位置两平面交线的端点、绘制两平面交线的正等轴测投影和三面投影。

Isometric drawing is much simpler than perspective drawing. Drawing instruments sre used to make the drawing in which the three principal axes make equal angles with the plane of projection.
