Introduction
The automotive industry in today’s world is stiffened by a very competitive environment
that presses companies to utilize the resources available such as workstations and engineers to
get the most out of them. The industry needs many diverse experts and a few specialists.
Investing in sturdy workstation components can bring the most out of the designers’ broader
skills thus enhancing the bottom line (Maloletnikov, 2014). Performance and versatility of
workstations are determined by how it is configured, graphics processing units, the central
processing unit, input/output components, memory, and storage. Depending on the data and
application you use daily will determine the choices of these components. Making the right
choices of the components will determine the performance of the workstations. The following
are some of the components that should be considered when building the workstation:
Central Processing Unit (CPU)
Over the years, processor technology has evolved from dual-core to hex-core with
multicore CPUs proving to be gaining theoretical speed-ups. However, for CAD workstations
you won’t get the best out of multi-core processors because the packages are not yet configured
to run on them (Green, 2017). For this case, get the single core processor with the highest
processing speed that you can afford. It is important to note that few CAD vendors are now
designing their components to operate on 64-bit multicore architecture. CPU is an essential
element for enduring that the workstation operates efficiently and utilizes the available resources
optimally. For the workstation, you should choose XEON or Intel I7.

Graphical Processing Unit (GPU)
When choosing a GPU one must be keen in choosing a GPU that will be used to power
the simulations applications, CAD, and the rendering process. The GPU of this era may have bit
similarities to the graphics controllers of the older days. With professional graphics, one can
display parts and models much more realistically and will also be able to keep the viewpoints
fluid even if working with sophisticated objects. These GPU’s will be able to offer a lot of power
just not in graphics but also in other fields. Graphics is only but a beginning for these new GPU
engines.
When the correct GPU is put in place, a remarkable performance will be noticed in how
the 3D software will respond to animation generation, panning, rotations, and other tasks that

CAD WORKSTATION 4
may push the limits of a much lower processor. Once this improvement is in place, the software
will be able to bring overall user satisfaction and dramatic gain in the productivity. The
consideration of a GPU will require both time and budget (Jovica, 2016). Most customers will
want an entry caliber card that will be able to match the performance and all capabilities of the
GPU with the rest of the system, for instance, an entry caliber workstation. The best way to
maximizing the ROI for the workstation purchase is by the right balance in which every
component will hit the performance level that it is supposed by the rest of the system.

The GPU Computing. There are two most common components in the iterative workflow
which are; FEA (Finite Element Analysis) and CFD (Computational Fluid Dynamic). They are
able to employ an algorithm that will rely on the heap of floating point arithmetic which also can
run in parallel to gain a significant increase in the throughput. Raytraced rendering is a technique
that falls naturally more on the GPU rather than graphics. It is different from the conventional
raster based rendering. The images that are rendered using the raytracer are more eye-catching
thus making the raytracer the most demanded visual tools used for product styling. NVIDIA
GPU has enabled Iray which is a rendering engine located mostly in software as Bunk speed
shot, the Autodesk 3d max and CATIA version6. The visual times are decreasing from hours to
minutes. At that speed, designers can be able to influence raytracing earlier in the development
procedure
NVIDIA Maximus is another GPU powered option available in major workshops such as
Lenovo, Dell, and Hp. It is used for the use of CAD and other professional related applications,
hence allow in ROI cranking visualization, ultimate concurrency, and analysis. NVIDIA Tesla
coprocessors and NVIDIA Quadro graphics are integrated, you will carry out simulations,
designing, and rendering processes on the same system.

Multi-monitor support supports a dual slot for CAD professionals and graphics which in
turn opens doors to a whole lot more screen real estate. With NVIDIA Quadro cards one can be
able to get unique Mosaic technologies that can be able to support as many and up to eight
monitors and also enable transparent scaling of any application as well as seamless taskbar
spanning. Also, nView technology is another unique feature. It allows one starts applications as
many 32 different desktops seamlessly switching in between them. There is a taskbar that shows
each application button on its specific display and lets you eliminate a single screen with an
overly crowded taskbar.

CAD WORKSTATION 7
When the performance requires an additional graphics cards, for example, high-end
graphics or mid-range graphics, one card will be enough to get all the screen real estate you
want.
There must be sufficient Ram in order CAD to run. The system RAM will depend on the
GPU that you will choose because the GPU have their internal memory which can be used to
free up the RAM in order to do other tasks. The speed of the RAM and its size will remarkably
influence the workstation performance much more than the CPU and GPU. The most advisable
and reasonable budget of a CAD application may range from 8 to 32 GB, but one can leave some
space in the DIMM slots located into the motherboard’s system for expansion later. For the ECC
(Error Correcting Code), it is not essential in CAD but is certainly valuable for allowing single
bit memory errors to be detected and corrected.
In order to make the right choice, one must give full consideration to the choice of the
CPU and GPU. The productivity will depend on the tools; hence, the performance of the
workstation will only be as good as the elements you selected (Covington, 2016). The memory
choice should be beefy enough so as to hold on all the computational horsepower.
Random Access Memory (RAM)
The abundance of fast and reliable RAM is crucial for the fast and smooth operations of a
CAD design for it requires a whole lot of memory. The 26 GB is the minimum, and the 32 GB is
more so for the professional use. The DDR4 is a must.

Storage (Solid-State –Drives)
This is highly recommended to build every PC with one and double for the CAD
workstations. The speed “05-6x over 7200 RPM platter drivers” are more impactful and real
hence increase the reliability. NVme SSD drivers like the Samsung 950 pro are mostly use for
the CAD workstations and are crazily fast for shut down, quick boot, and program launching as
well as an overall snappier feel. The SSD and the Hybrid SSD will be able to load up large
assembly files. The faster the Hard Drive, the faster the files will be loaded on the desk or RAM,

for the Hard Drive acts as a filing cabinet. If the Ram runs out, the Hard Drive Virtual Memory
is used for file swapping.

Input/output Devices
There are others which may include, ten screens, one screen, 3D mouse, and ergo keyboard

Vendor
Vendors such as Dell, HP, and Lenovo have a CAD level category of mobile and desktop
workstations which will have most if not all of the recommendations required, but one can look
at clone to save in money. For this case, I recommend acquisition of Inventor workstation from
Autodesk. The vendor has been in the industry for the more 30 years and understood the industry
requirements. Autodesk inventor will bring several benefits to the company by facilitating 3D
modeling rapidly, digital prototyping, and design of products.

It can reduce the time required to design and model a product, assessment of global
impact to the product, and potential design visualization. Autodesk inventor should be
implemented in well specified and suitable components to avoid time wastage and nullification
of it benefits. Due to the vast amount of data, the company will be supplying to the Autodesk
inventor; I recommend the following components to work with Autodesk Inventor:
