project pattern of sketches to a single sketch

YY110032788 — Mon, 27 Jan 2025 07:10:50 GMT

Hi all,

I'm using Creo parametric 11.0.1.0.
I have a pattern of sketches. Is it possible to project the pattern associatively to a single sketch?

I attempted to select the rule "All curves in feature" in Rule-based references via the chain selection option, but was unsuccessful.

What'm I doing wrong? Is there an alternative method that works?

Thanks

I don't know of any method to do what you want. You can do a massive selection of curves to project in the "composite" sketch, but that is a "dumb" sketch, not driven by the pattern. The only time I've used patterned sketches is to display a layup of features and visually check for interference, etc. Usually, I'll build a feature based upon the geometry I'd have in the sketch, then pattern that feature. Any adjustments to number of features, spacing, etc. are then simple and direct.

Create the lead feature of interest first, pattern the feature (in a solid or surface model) as suggested by @KenFarley . Once you have the patterned features you can use the loop selection during the project operation to streamline the selection of all needed curves. Depending on your model topology (which I have not seen) it could be a single selection operation to get all of the curves.

This method may or may not be the best way to get what you need but it can work on some geometries.

@KenFarley and @tbraxton , thank you for your response.

According to what I read between the lines, my requirement is not currently available in Creo.

This is an alternative method that will work for some scenarios. Here a pattern of a datum points is used to define the pattern instance locations and then a sketch references these datum points to realize the design intent that you want.

Creo 7 model enclosed for reference.

Hi @Catalina

Unfortunately, I did not get a solution for my need.

Thnaks,

Hi,

For me it is not exactly clear what your intention is, to create one sketch containing the complete pattern or create an associative projection.

You can not associate it parametrically to one sketch. In Creo you would typically use a ref-pattern to associate the projected sketches.
