I have worked fairly extensively with Solidworks in a few different capacities:
Concept-level models Top two examples at right
These type of models are designed to convey the concept, general layout, or basic functionality of a future design. These can be very useful when writing grants or proposals, as they allow for the use of "black-box" diagrams, which convey an idea but doesn't require the unnecessary work of modeling all dimensions in exact detail.
Prototype-level models Third example at right
These models are for use in system design, and all dimensions must be accurate. I most often made these types of models for enclosure and housing design. In these situations, I individually modeled all internal components exactly, and then arranged them in assemblies to consider different possible enclosure layouts. I then used these models as references to create the CAD models of the box/enclosure itself in Front Panel Designer.
Models for 3D Printing Bottom example at right
These models are created to exact dimensions, and are then 3D printed. I have used this to produce pieces for high-voltage standoff and baffle pieces for guiding airflow.
Beyond the tutorials included with the Solidworks software, I am dominantly self-taught. Because of this, and the variety of contexts in which I've modeled, I have become a flexible designer and can fluidly adapt to the needs of the specific project at hand. I most enjoy working on projects that represent real-life models, either before or after their creation, as I find the real-world validation very satisfying!
My design work has been deeply informed by the fact that after CAD modeling, I often construct the objects myself. As a result, I have developed an intuitive understanding of machining tolerances, an appreciation for design simplicity, and a solid ability to think through the challenges associated with manufacturing and assembly.
