Blast from the Past: History and Sketching

[editor] With this article I reach back to consider some of the contradictions of sketching in a history-based system. If history isn’t necessary for sketches, why should it be needed for other constructions? Parts of this have been edited to fit with current realities, it was originally published 3 years ago.[editor]

Solid Edge XpresRoute

Today I decided to do the Solid Edge tutorial on tubing and piping, using XpresRoute. Picking this up was easy. For simple here-to-there routes, Solid Edge runs the routing lines itself. You can intervene with a 3D sketch tool. The OrientXpress, the big origin axes, enables you to select an axis or plane to draw parallel to. Its far more intuitive than the Tab, Tab, Tab method from that other software. I found the Solid Edge method to be more solid, easier to use, and much more reliable than the other software. It just seems like Solid Edge doesn’t make a big deal about functionality that should just work. Solid Edge provides a bend table for each length of formed tube. Read more on Solid Edge XpresRoute…

Synchronous Sketching, Spaceball bugs, BlueDots

I’m jumping in right now to play around with synchronous sketching, and I’m finding something I’m not too impressed with. Is this Matt-the-Noob ready to learn something new? or is this a weakness in the tool? Watch the movie and tell me which it is. Read more on Synchronous Sketching, Spaceball bugs, BlueDots…

Synchronous Sketches with Ordered Features

This is a topic that some may initially find a little esoteric, maybe even dull to some. But I assure you, it has big implications. If your favorite history-based software had this sort of functionality, you might feel better about history.

In history-based modeling, you usually think of sketches as being history-based too. Not inside the sketch, but each group of entities grouped as a “sketch” has a certain order, and can even have parent-child relations with other sketches. In some of my posts on the Dezignstuff blog about how to improve history-based  modeling, I suggested that a single sketch environment that wasn’t split up into separate “sketches” would make more sense and be easier to edit than the current deal where you get “out” of one sketch and “in” to another. This slows things down so much. Read more on Synchronous Sketches with Ordered Features…

SEv SW: Sketching, Part 2

The hard part of being a noob is that sometimes you don’t really recognize what’s important and what’s not right away. In comparing Solid Edge to SW, you have to realize that sketches have different relative importance in the two packages. In SW, most of your design intent is established in the sketch. In SE, this is only true if you are working in ordered mode. Remember ordered mode is just using Solid Edge as a history-based modeler. Sketches in Synchronous mode are stored, but they aren’t associated with anything. Luc (Solid DNA) showed a couple of nice movies to show how unimportant sketches are in SE.

Solid Edge vs SolidWorks: Sketching, Part 1

There’s nothing meaningful I could do to compare the entire Solid Edge and SolidWorks programs in a single blog post. That’s why when I have taken the topic up on the Dezignstuff blog, I would bite off “small” areas like surfacing, sheet metal, or the overall interface. In this case I’m going to look at sketching, arguably the single most important function of any CAD program.

You might think Solid Edge and SolidWorks sketchers are pretty similar because they both use the (Siemens) Dcubed constraint solver. In the end, that similarity probably means that they share the strengths and weaknesses of Dcubed, but the comparison can’t be limited to that. The differences between them are much more structural. When you consider that Synchronous Technology has a big impact on sketching, the conceptual differences become even larger. Read more on Solid Edge vs SolidWorks: Sketching, Part 1…
