إن الهدف النهائي من جميع الأجزاء النظرية والتطبيقية في هذا المساق هو حث الطالب على ممارسة التفكير الفراغي لفهم القواعد الهندسية للفضاء الهندسي وتمثيله بطريقة لا لبس فيها، سواء من الناحية التقنية (الاسقاطات العمودية والاكسنومتري) او الادراكية (المنظور والظلال)

Notes on the Ease of Using Cavalier Axonometric Projections
Due to the ease of execution of axonometric drawings compared to perspective drawings, it makes sense to use the simpler types of axonometric projections, such as cavalier and cabinet. In cavalier projection, the projections of shapes belonging to horizontal planes remain in their true form, while the projections of shapes belonging to other planes get distorted. However, the measurements of vertical lines (parallel to the z-axis) can remain equal to their true measurements when the projection center direction is 45 degrees relative to the plane of projection. Similarly, in cabinet projection, the shapes belonging to the zx or (yz) plane are drawn in their true form, and the measurements of lines parallel to the x or y-axis can also remain without distortion.
The simpler types of axonometric projections: plan oblique and elevation oblique
It's important to note that all types of axonometric projections are not an exact representation of reality and cannot replace perspective drawings. However, they are a useful tool for architects and engineers to show three-dimensional configurations in a clear and quick way. [1]
