Synchronous Technology and Best Practice

burning-money

I’m someone who has written a fair number of “Best Practice” lists. My CAD Administration book in particular was full of recommendations for everything from installing software to surfacing design. People assume that a best practice list is really a set of rules, but those people are wrong. Best practice is really a set of suggestions that are meant to serve the lowest common denominator in an engineering office. It’s a flexible attempt to standardize practices when you have people in your office who aren’t expert level.

Design is NOT a Linear Process

Those of you who have been working in design for more than a couple of years, and I’d assume that’s most of you, already know that design is not a linear process. You may start in one place, and jump around, and eventually come back to where you started. You may revisit the same area of the design multiple times. Of course this isn’t the most efficient way to work, but you don’t get your information in perfect order, or you may not see a solution for a problem until you’re half way through. Or the requirements change part way through the design process. We all know stuff happens. Lots of things happen, and people are imperfect, so you never go through a project (at least in my experience) straight from top to bottom on each part.

History AND Direct?

I assume I’m talking to all the smart kids in class. Just because you’re engineers and designers, well, all that math and science weeded out the rest, right? And of course I assume that as the smart kids in class, we all watch the Big Bang Theory, and can relate to the problems of nerds. Sheldon, Leonard, Howard, Raj, Amy and Bernadette each provides something for us to relate to. Sometimes in a “yeah, that happens to me all the time” sort of way, and sometimes in a “don’t you hate when that happens” way.

Flexible Design Intent

0012

0012The first time I saw a demo like this, I flipped. This kind of history-independent power should really be turning some heads. Just to sum it up for you, what it happening in the video below is that you can make features dependent on existing geometry, and then use either the new or old geometry as driving features. No stupid tricks, this is just the way it works. To Solid Edge, it’s just geometry. There is no method to make it, no forced metaphors like baking a recipe, or writing a computer program. It’s just geometry. Think about changing sketches, and that’s the kind of flexibility you have with changing 3D parts in Solid Edge Synchronous Technology.

Synchronous Assemblies Brief Demo

synchassemblies3

The whole thrust of this post is that in Solid Edge Synchronous Assemblies, you can design parts in the context of the assembly without creating any of the synchassembly1debilitating effects of references between parts. So you can make design intent go back and forth between parts, which you can’t do in your old CAD system because of “circular references”. You can make references to a part in one assembly, put it in another assembly, and make different references without the dreaded “multiple contexts” error. And you can rename or replace parts with similar parts without having anything going haywire on you.

Blast from the Past: Can Parametrics Exist Without History?

0004

[editor]: This was a post written five years ago about the possibility of using familiar parametric design ideas with history-free models. Here I’m trying to get my head around the idea, and trying to introduce readers to the concept that maybe history-based modeling isn’t the only game in town.

Why I Changed Camps: Part 2

suffering_in_agony_for_sins

Part 2 is all about the role that the technology played in my switch. Going from a skeptic to a supporter seems like a big jump, but if I explain this right, it will be obvious. The functional differences to me are compelling, especially for the kind of work that the largest group of mid-range CAD users do – machine design, which uses primarily prismatic shapes.

Why I Changed Camps: Part 1

dummies-change-1-0

imagesI get contacted every now and then by people or companies doing research before buying a new CAD package.They are interested in the story of a prominent user changing camps. Since I took down the Dezignstuff blog, most of the story that took me from SolidWorks posterboy to Solid Edge employee has been lost. I just want to have the real story on the record and available to those who are curious.
