Why in creo sketch there are no linear and circular pattern options?

Why in creo sketch there are no linear and circular pattern options?

Dear Creo users,

While doing some complicated sketch don't you think there is a need of linear and circular pattern options in creo sketch? Its true pattern option is given in solid modelling and we can pattern a feature or group of features. In solid works users can pattern inside sketch mode. in creo 3.0 and 4.0 is there any updates on sketch pattern? I am using creo 2.0.

With regards,

Soumya

There is no pattern function inside sketcher in Core 3.0. As far as I know, the workaround is to make a sketch, and than pattern the whole sketch. As a previous SolidWorks user, I find this very annoying.

Because Creo is not Solidworks

Hi,

in Creo 3.0 and 4.0 you also cannot pattern geometry in Sketcher mode.

Re: Why in creo sketch there are no linear and circular pattern options?

when do you want to pattern inside a sketch? Seems like you would create an unnecessary complicated sketch? Please enlighten me!

This is PTC's strategy to keep sketch as simple as possible, so no linear or circular pattern. Also there is no need to do so. I have used CATIA sketcher, NX sketcher and Solidworks as well, but honestly speaking Creo sketcher is the fastest.

If you need to use linear or circular pattern, you probably want to have a 2D sketch, and Creo is not meant for this purpose.

Re: Why in creo sketch there are no linear and circular pattern options?

Complex sketches is one of Creo's strong points.  And I love them.  But Sketch patterns were not a concept for early developers and today, there is no push to add it.  This would be a serious re-write.  Not to mention that the SW version is far from robust.  PTC doesn't do anything unless they have the opportunity to make it 10x what SW would have.

What I really miss is "midplane"... just as a matter of convenience.  That may have other implications to incorporate.

I am probably not expereinced enough Creo user to give a credible opinion on this, but after more than a year of 10 hours per day in Creo, i still find sketching bad. Offset and project sketch specially. The contour is never ever whole, always space -red dots- between lines. Sometimes even on very simple geometry.

Re: Why in creo sketch there are no linear and circular pattern options?

I like the complex sketches, too. With some reservations. I've had some devastating failures where the a sketch that I got too ambitious with suddenly went "unstable". Usually this happens with geometry where I have a lot of arcs in a profile with fillets on those arcs, etc. Creo gives me the opportunity to automatically "fix" the sketch, but the fixing seems to be more in the line of how a veterinarian will "fix" your dog. It deletes all the dimensions and leaves me with a random-ish assortment of abstract artwork.

I've learned, through a lot of negative consequences, to not try to be so fancy with my sketches, and maybe break them up into multiple simpler sketches.

Re: Why in creo sketch there are no linear and circular pattern options?

Kenneth, have you tried tightening up your precision?

Most work well for me by default at the scale I work.

Could sketcher be improved?  Sure!

Will it be improved?  Doubtful.
