In-Depth Information
engineering modifications you have had to implement in production, for example jigs, fix-
tures, fittings etc. Now look at the extensive list of advantages in the 'Significant Benefits
of 3D CAD and Digital Engineering' section. Tailor these examples to your unique busi-
ness circumstances. Specifically mention your products, your costs, your departments and
people, as well as your suppliers. As ever, quantify wherever possible. Use known factual
examples, figures and amounts where 3D CAD could have assisted you during develop-
ment. Consider approaching 3D CAD suppliers for their experience in convincing senior
management teams. Quantifying improvements is also important - consider money, time
saved and quality improvements (such as number of defects, often measured by engineer-
ing change requests). Realistic facts and figures are crucial for adding to the credibility of
your case. Ultimately, aim to make it very difficult for senior managers to say no.
7. CAD Software Evaluation and Selection
So, you're thinking of taking the plunge? Whether you are considering investing in 3D
CAD for the first time or expanding what you've got, it's critical to select the software that
best meets the unique requirements of your business. Start by identifying your business's
unique CAD requirements. Which business objectives are you attempting to address? What
business processes are you attempting to improve? For example, new product introduction,
existing product redesign or alternatively production engineering improvements, such as
jig and fixture design or the introduction of Computer Aided manufacturing.
To assist, consider the following questions: What is your budget? When do you need it up
and running by? How many CAD seats do you require? Who will use the CAD software
and for what specific purpose? What are you training considerations? Have you thought
about support and maintenance? Are there any special CAD features or modules that are
ideal for the nature of your business? What are your hardware, network and systems re-
quirements? Are upgrades necessary? What about your data management requirements?
Have you considered the workstation location and design environment and are they condu-
cive to CAD work?
Put together a CAD specification tailored to your business. Prioritise your list of require-
ments. Next, undertake some research and investigation into 3D CAD Software.
Compare the CAD software packages on a range of criteria most relevant to your business.
After careful examination, consider using a simple score and ranking system to rate the
CAD packages. Depending on the outcome, you may decide to make your final purchasing
decision, or call the top couple of vendors in for a demo.
