Enjoy Flexible Product Design with ZW3D
ZW3D CAD/CAM White Paper
April, 2014

Overview
User experience (UX) has always been a major talking point, with visual impact a crucial
part. People prefer products with eye-catching shapes, while designers are facing more
design challenges than ever, requiring faster sketching, flexible modeling, and high quality
surfaces etc. If you are facing any design challenges or would like to know more about
product design, then this white paper deserves your time to read.
Figure1: The process of product design
The whole product design process involves many factors such as drafting, modeling,
rendering, as well as a lot of other techniques and, of course, designer’s creativity. Each
element of the design process must combine with each other. Typically, most product
designs start from sketches and end up with solid models.
Figure2: Product design
From following inquiry research of 100 designers, we find that the most important parts in
design process include sketching, surface quality and flexible modeling.

1. Easy to Use
Product design used to be a purely professional activity, as the tools were difficult to learn
and use. Nowadays, however, the ribbon interface and quick help system shorten the
learning curve greatly. With simple operations, great designs can be finished easily, as
shown in figure 4. (Furthermore, the parametric technology helps to modify and update
the product design immediately)

2. Flexibility
Flexibility is the most important issue affecting the design process. If we conduct a deeper
analysis, we find that flexibility involves sketching flexibility, modeling flexibility, editing
flexibility, documentation flexibility.
2.1. Sketching Flexibility
The flexibility of sketching allows for both easier creation and modification of models in
ZW3D. Take the following figure 5 as an example. Using the built-in sketching library, it is
easy to create standard sketches. Furthermore, it is easy to generate different kinds of
sketches in seconds using the equation curve. Adjustment can be made with a simply
drag and drop operation.

2.2. Modeling Flexibility
The flexibility of modeling tools is hugely important, which can influence the creativity of
designers.
The principles of solid modeling and surface modeling are very different. Previously,
designers were required to distinguish between different modeling commands. ZW3D’s
unique Solid-Surface Hybrid Modeling technology, however, eliminates this barrier
between solid modeling and surface modeling. It delivers much more user-friendly
experience and more flexibility in creating 3D models, since the Boolean operation works
for both solid and surface geometries, as shown in the following figure.
Figure6: The hybrid modeling processes
Except for general modeling, serial designs of products and deformation designs are also
very important for designers. Part configuration allows designers to build parts variations
conveniently through adjusting parameters and managing features. What’s more, by
taking advantage of the flexibility of the Morphing, Wrapping and Flex Tools, simply with
one button, new style products can be generated.
1) Part configuration
In one part, by suppressing the features and setting different feature sizes, several
different part statuses can be generated quickly. In an assembly, any configuration of
this part can be called directly. It is a very efficient method of undertaking serial
product design.

2) Morphing
The transformation of parts used to be difficult, requiring designers to create surfaces.
Instead, with the Morphing capability, shapes can be adjusted and accepted once the
visual impact achieves the required result.

3) Flex Tools
No matter if you would like to design rings, bottles or shoes, the FlexTools allows you
to map the shape and create the transformation as desired

Figure9: Wrap a shape to a target face
2.3. High-Quality Surface
Generally, in order to build products with the best surfaces, continuous curves and
surfaces are essential, as shown in figure 12. Surfaces can be generated from curves,
and continuous curves allow you to generate a continuous surface. Furthermore, the
curvature tools help improve the quality of the curve or surface during the operation。
Figure12: Create a continuous surface with a continuous curve
2.4. Assembly Modeling
Any product is composed of many different parts.ZW3D supports not only Bottom-up
assembly design but also Top-down assembly deign. Flexible assembly design can meet
different needs of designers. Both the design of independent part and the update of
associative parts can be done easily in ZW3D.

Figure11: Flexible assembly design
2.5. Editing Flexibility
During product design, the structure of the product must be continually modified in order
to coordinate the assembly and production. Occasionally, partial modification of external
models is required. With parametric modeling and Direct Edit tools, designers can perform
the adjustment of models easily and quickly in every stage of product designing.
Meanwhile, we can use the feature frozen function to freeze some features which do not
need to be changed. This can prevent unexpected model change, avoid model
regeneration failure and reduce the history regeneration time, thereby improving
efficiency.

2.6. Documentation Flexibility
The flexibility of the documentation is indispensible for design collaboration. Both 2D and
3D documentation are considered in ZW3D; 2D documentation can be achieved with only
2D drafting, while the 3D PDF shows the model in 3D in a simple PDF document without
the need for further 3D software.
3. Conclusion
Apart from what we covered above, there is much more that can be explored in ZW3D. No
matter what you design, the flexibility of ZW3D allows you to save time and money, while
the simple user interface will speed up the process and allow you to focus on more
creative work.
