Macbook Pro For Engineer
Pro Engineer Creo Mac

Hello!

I will be starting my Engineering Studies this Fall. I will be doing several types of engineering (Aerospace, Mechanical, Electrical, and Computer). I will also be doing several virtual labs. I have been using a macbook for 7 years and I love it. However I have not used it for any engineering programs. I will be needing to buy a new computer and I am trying to figure out of going with a windows based computer would be more beneficial than getting a mac. I was thinking of going with a MacBook Pro 15'. I know I will be using AutoCad and MatLab. I just want to get the best machine for my needs. I would love to get a mac again, but I have heard lots of conflicting information. Would anyone be able to help me with this?

A great deal of digital ink has been spilled (pixels have been randomly arranged?) over whether the iPad is actually a useful productivity tool and much of it has been written by artists, technology journalists and bloggers, but I have yet to see much of a comprehensive examination of the iPad from an engineering perspective.

Before I go further, if you prefer listening to podcasts, I talk about it extensively on Episode 68: Paperless of Pragmatic on The Engineered Network.

I know several other engineers that aren’t interested in the Apple cult, and prefer the configurability of Microsoft products of the past and they latched on to the Surface when it came out however reports of its sluggishness and heft as a tablet made it more of a laptop with a detachable keyboard than an actual tablet, and the Surface Pen was not held in very high regard either. I heard of issues with palm rejection and accuracy as well as lag, but observation is the best tell and I’ve observed those people using their Surface almost exclusively as a laptop, and seldom if ever using the Pen.

As I am more personally invested in the Apple ecosystem, I’ve owned and throughly used an iPad 1, iPad 2, iPad Air, iPad Mini, iPad Mini 2 and now an iPad Pro. In that time I’ve used a Griffin 2-in-1 Pen/Capacitive Stylus, an Adonit Jot Pro and now an Apple Pencil. So with those qualifications out of the way…

What’s Special About Engineering?

Engineering involves conveying a lot of information diagrammatically and it’s not the only profession that does. In that sense marking up drawings, flow charts, red lines and whiteboards are our tools for this job, but what frustrates me more than the old tongue in cheek comment “the age of the paperless office” which apparently happened in the 80s but the world must have missed it somehow, as I intuitively know that moment is coming. What device/service or combination thereof will finally deliver on that promise-turned-running-gag?

To be effective as an engineering tool for me personally it needs to solve several problems I have:

An engineering notebook everywhere that stores sketches, handwritten as well as typed notes
Accurate markups of PDFs without loss of resolution
Creating flow charts and diagrams quickly and easily
Portable enough to take everywhere with me
Able to physically sign documents, in Word and PDFs accurately

The goals are to eliminate three issues I encounter every day at work:

I need to carry three pens everywhere (Blue, Black and Red) and they leak, they get lost, they run out of ink, they suck
I currently have to print a document, write my markups on it, then scan it in again which erodes the resolution every time and makes the original document unsearchable even with the best OCR software currently available.
I make notes in my engineering notebook (a legal requirement) and need to take it everywhere with me but its size is limited so I move from book to book with transitional periods between books requiring that I carry multiple at once.

iPad for Engineering: Take 1

The iPad Pro for engineering is therefore first and foremost about the stylus, but the ability to use the device with a touch screen keyboard would be a huge plus as well if it could pull it off. That said I’d tried styluses before without much luck and touch screen keyboards as well without any success, so call me skeptical from the outset.

I drew several Enginerd comic strips using my iPad Mini 2 and the Griffin and Adonit mentioned previously but to be honest it was difficult and frustrating. I tried to use older iPads and styluses at work and the two big issues that kept arising were:

Stylus accuracy and speed made drawing markups, signatures and notes effectively impossible to do
I found myself regularly erasing and trying strokes and signatures again and again and eventually giving up (signatures bared no resemblance to my signature with a traditional pen and paper)
Typing was slow because the key sizes on the Mini were too cramped and on the original iPad the typing lag was beyond horrible much of the time

Of course the typing problems of an iPad can be overcome in some ways by using an external keyboard. To that end I used an original iPad keyboard dock with all of the models from time to time, even using a 30-pin dock to lightning adaptor with a box of old business cards to support the weight of the iPad (a trick that worked fine until the iPad Pro came about). It was excellent, however only useful on my desktop at work and for portability to meetings and on the train it was useless.

I also tried the Clamcase, but it just wasn’t stable enough even on the train with the keyboard component regularly disconnecting and being horribly sluggish at the best of times. I wrote about it, I podcasted about it and honestly I gave up on the iPad as an engineering productivity tool.

That was, until the iPad Pro and the Apple Pencil were released.

iPad for Engineering: Take 2

Ever willing to give technology another chance, I obtained an iPad Pro, Apple Pencil and Smart Cover and took it to work for several weeks in the lead up to Christmas determined that if it didn’t work out, I would return them. If they couldn’t earn their place then they had no place. The TL;DR: I still have them all.

Double Touch Typing

Yes I did a year of typing classes at high school and I’m a touch typist as a result of those hard yards. Keyboard key spacing is critical when I’m going from device to device. I’ve tried many times to use touch screen keyboards for touch typing, but there have always been two issues: No locators for your index fingers (see those notches on your F and J keys on your physical keyboard? Yeah those things) and the key-sizing and inter-key spacing a were always just off/small enough such that when typing on the screen like it was a physical keyboard, many keys didn’t align. Typing on older/smaller iPads was slower, very inaccurate and ultimately frustrating typing and in the end I just gave up.

When I’m talking about key-sizing and inter-key spacing, what I’m referring to is that the physical dimensions of the screens on iPads make it physically impossible to create a virtual keyboard that matches a physical equivalent. The same is true of the iPad Pro, actually but it’s damned close. The key sizes and spacing on the iPads 1, 2, Mini, Pro, Smart Keyboard and a Apple Wireless keyboard for comparative purposes as shown below:

Device / Keyboard	Width (mm)	Height (mm)	Key Spacing (mm)
iPad Mini Landscape	12	11.5	14.5
iPad Pro Portrait	12	11.5	13.5
iPad 1 & 2 Landscape	15	14	17
iPad Pro Landscape	16	15	18
iPad Pro Smart Keyboard	15	14.5
