Extrusions are the most basic solid shape to create in Computer Aided Design. Here, I am creating an extrusion in OnShape. I start by selecting a plane, creating a sketch, and then selecting the “Extrude” command. This lets me add volume to the sketch. All 3D volumes in CAD are considered extrusions, and this is…

I have been playing around with the Arduino Uno rev4 Wifi hobby circuit board and I have to say it’s very user friendly! Here I have it hooked up to a 180 degree servo motor testing out its capabilities for controlling motion. The Arduino IDE, the program where users write code and upload it to…

Process Engineers are engineers that focus on processing raw materials and chemicals into a desired product. They commonly have degrees in Chemical Engineering, Mechanical Engineering, and Industrial Engineering. Process Engineers are common in manufacturing fields involved in pharmaceutical production, oil and mining, and processed food. They are often involved in specifying the order and type…

Engineering drawings are used by engineers to communicate with manufacturers when ordering physical components and products to be made. They generally show a front and side view of the product with annotations of critical dimensions. There is also generally a notes section in a corner of the drawing for communication important details to the manufacturer…

The Revolve command is very useful for making solids that are radially symmetric. In this demo, I’m creating a cup in OnShape. I make a sketch on the Front plane for one profile of the cup, and I created a sketch with a line along the y-axis.

Biological Engineers are another type of engineering discipline that is closer to the sciences. Biological engineers have a heavy foundation in biology and chemistry, as well as studying subjects similar to mechanical engineers such as fluid dynamics. Undergraduate students can major in biological engineering and often pursue advanced degrees. Academic research and industry careers, particularly…

Drawings are a very important tool for communicating ideas for many engineering disciplines, especially product engineers. Product engineers often have a mechanical engineering background, and design physical products for consumer use. This is an example of a drawing made on a tablet which offers convenience for several reasons. Drawing diagrams on a tablet provides a…

Here, I am creating a hollow object using OnShape as my Computer Aided Design program. I start by creating a solid extrusion, and then I select the shell feature. After selecting the shell feature, I select a surface on the extrusion that I want to be open. The extrusion is then hollowed out with the…

There are several types of engineers beyond the traditional mechanical engineers and electrical engineers that most people think of. Aerospace engineers work on aircraft like planes, helicopters, and rockets. They can even be valuable in automotive engineering for their expertise in aerodynamic designs that improve energy usage and speed. They generally have at least an…
