Feature Pattern vs. Sketch Step and Repeat
Feature Pattern vs. Sketch Step and Repeat
(OP)
I'm working on our "Best Practices" guide >:-O
Is there a general consensus as to which is a better practice....use Feature Patterning or Sketch Step and Repeat patterning? I understand that the design intent and part revision is a huge part of the eqation but I'm also interested in the performance of the part.
If you have a part with multiple patterned features, will it perform better than if you pattern the features in the sketch? In simple tests I've done, the file sizes between the two are very similar.
Any opinions?
Thanks!!

SIDE NOTE: Do not confuse sketch "step-and-repeat" with "Sketch-driven pattern".

If the Fixed option is used when creating the pattern, the "pitch" can also be modified.
It's clunky, but does work. Hate to admit it, but SE's Pattern Fill is much better.

Check out Matt Lombard's site here:

Look under Rules of Thumb: Patterns
In summary, Feature patterns are almost always preferable to a step and repeat in a sketch for almost every reason (performance, design intent, configurability, editability...)
Sketch patterns do have their place, but usually a feature pattern is the best option if at all possible.
RE: Feature Pattern vs. Sketch Step and Repeat
It is not possible to add entities to a sketch step-and-repeat. It is possible to change number of instances, though.
For instance:
•Make a sketch-and-repeat pattern of a simple sketched rectangle.
•Close the sketch.
•Open the sketch, modify the "root" rectangle by adding an entity to its contour (like a corner chamfer).
•RESULT: You will find that this change can't be propagated throughout the sketch-and-repeat pattern.
