How I Make My CAD Models Easier for Others (and Myself) to Understand, Use, and Update
Sometimes the hardest part of CAD design isn鈥檛 the part itself but making it quick and easy to reuse and/or modify in the future. I鈥檝e seen smart engineers struggle with messy feature trees, broken references, and CAD files that only make sense to the person who created them. We鈥檝e all been there and know how frustrating it can be. In this article, I鈥檒l walk through what makes CAD models hard to understand, what information should always be included,…

Read MoreCES 2026 Recap: Field Notes from the Floor
We just got back from CES 2026, and we鈥檙e still sorting through everything we saw. Rather than summarizing every booth and headline, we did something simple: we asked two teammates to share their biggest takeaways from the week. Below, each section is written in the author鈥檚 own voice. If you鈥檙e deciding what to build next, what tech is worth…
Read MoreCustom PCB Design vs. Off-the-shelf Boards: Which Is Right for Your Product?
A common question we hear from startups, product owners, and even seasoned engineering teams is this: Do we need a custom PCB design, or will an off-the-shelf board work just fine? What’s great about this question is that it’s not just a technical one, it’s also a business one. There are multiple factors to consider,…
Read MoreProject Management vs. Project Leadership: What’s the Difference and Why It Matters
You鈥檝e likely heard a lot about project management, both within the field of engineering and outside of it. You might even have 鈥減roject manager鈥 in your title. This is all for good reason; managing budgets, timelines, and deliverables is needed for any successful project. But there鈥檚 another important piece that doesn鈥檛 get as much attention:…
Read MorePlant Maintenance Shouldn’t Be Reactive鈥擧ere’s How to Get Ahead
Smooth startups are great, but the real challenge lies in keeping equipment running at peak performance after installation. I鈥檝e seen it too many times: the first few months go well, production hums along, and then… the machines go down unexpectedly. Those once seemingly insignificant parts are missing when you need them, preventative maintenance is hit-or-miss,…
Read MoreThe A-Surface Modeling Debate: Which CAD Software Reigns Supreme?
If you鈥檝e ever been part of a product development team, especially in automotive, aerospace, or consumer goods, you鈥檝e likely witnessed (or participated in) the age-old debate: What鈥檚 the best software for A-Surface modeling? At our office, it’s a topic that comes up again and again, and for good reason. From CATIA to NX, Creo, Rhino,…
Read MoreUnexpected Parallels Between Product Development and Jiu Jitsu
Twice a year, DISHER holds team offsites to evaluate progress, make improvements, and build connections. At one event, I mentioned wanting my three kids to try martial arts. My colleagues, Collin and Jeff, recommended Jiu Jitsu, emphasizing how beneficial it is for kids due to its complexity and cognitive benefits. My middle child asked if…
Read More7 Essential Strategies for Debugging Software
We鈥檝e all had to troubleshoot technology at some point. Maybe it was resetting the microwave clock after a power outage, reconnecting a smart speaker that mysteriously dropped off the Wi-Fi, or figuring out why your printer refuses to print unless it鈥檚 in a particularly good mood. Even if you don鈥檛 write code, debugging is a…
Read MoreThe Developer’s Debugging Toolkit
Debugging can feel like solving a mystery, except the clues are buried in code, hardware, or network logs. Before you start, it鈥檚 important to take inventory of all your tools. The tools might look a little different depending on the domain you鈥檙e working in, but having the right ones at your disposal can make the…
