Space Modeling With SolidWorks and NX
Jože Duhovnik, Ivan Demsar, Primož Drešar
Through a series of step-by-step tutorials and numerous hands-on exercises, this book aims to equip the reader with both a good understanding of the importance of space in the abstract world of engineers and the ability to create a model of a product in virtual space – a skill essential for any designer or engineer who needs to present ideas concerning a particular product within a professional environment. The exercises progress logically from the simple to the more complex; while Solid Works or NX is the software used, the underlying philosophy is applicable to all modeling software. In each case, the explanation covers the entire procedure from the basic idea and production capabilities through to the real model; the conversion from 3D model to 2D manufacturing drawing is also clearly explained. Topics covered include modeling of prism, axisymmetric, symmetric and sophisticated shapes; digitization of physical models using modeling software; creation of a CAD model starting from a physical model; free form surface modeling; modeling of product assemblies following bottom-up and top-down principles; and the presentation of a product in accordance with the rules of technical documentation. This book, which includes more than 500 figures, will be ideal for students wishing to gain a sound grasp of space modeling techniques. Academics and professionals will find it to be an excellent teaching and research aid, and an easy-to-use guide.
A routine is established through work, similar to getting fit in sport. It makes sense that professional designers and engineers are skilled in the art of sketching. Generally, however, their sketching abilities are near perfect. Sketching allows them to communicate abstractions from the metaphysical part of their brains as a document for themselves and others. Sketching is also used so as to be able to quickly present, in a graphical form, an idea that is related to a particular problem.
that sketching is not just a matter of engineering but also serves as a basis for other human expressions, such as art. The message of an artistic sketch is based on the metaphysics of the artist’s cognition of the world, so an artistic sketch conveys a different message. In both cases, proficiency is represented by the creativity of a creator, so the expressing exclusiveness of the respective creations (engineering and artistic sketches) is unique to each creator. It also shows how important an

Subsequently, we perform an extrusion with a depth of 4 mm (Fig. 5.41). 5.4 Modelling in NX 123 Fig. 5.40 Modelling of a four-sided prism in the shape of a cone for modelling an extrusion 30 × 10 mm on the top part of the model 5.4.8 Modelling of Through Holes φ8.5 mm on the
