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.
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.
Yes, I've tightened up precision, etc. The trouble seems to be a persistent one with Creo where it seems to get "confused" about tangent arcs and which "side" of them it needs to "keep". Similar to the unpleasant results one gets if they pattern something circularly and attempt to go beyond 180 degrees. Works for a pattern around an axis, but don't bet on it if you want to use a dimension to do it.
Antonius Dirriwachter In creo 4, there is an option for creating a datum midplane (if that´s what you meant by "midplane" , or maybe you were talking about something in sketcher thats missing?)
Any incorporation of a midplane modifier is exiting! Looking forward to it.
Hi all , Don't you think that this sketch can be better drawn by using sketch pattern option if it is in Creo sketch?
I have seen an option called copy and paste special in creo sketch. In this option have anyone tried to rotate a copy of sketch at a specified angle?
Thanks for all your replies. Any other suggestions or discussions will be helpful.
Is there any portion in this community or ways to request or connect PTC Developers about some enhancement that creo users like to request?
Maybe it's a matter of preference or just the way I learned to use ProE but I wouldn't include all that detail in a single sketch feature. Not that it necessarily is but I think I would find it easier to create the ears and the associated holes as their own features or group of features and pattern that. You also lose the advantages a feature pattern can offer although you do have other options you could use for those.
That sketch would be way to fragile. Patterns in sketches are very fragile and limited in SW.
I could easily constrain that part in one sketch without having to go back and try to clean up a messy merge of a pattern in the sketch.
However, I too would use about 4 features patterned in the conventional sense. 2-3 minutes tops... single sketch method, maybe 5.
Sustainability; Multi-feature will win the error search much easier. Feature patterns are easily edited where sketch patterns in SW are not.
I would never try to model that part using just one sketch/extrude.
Like Antonius, I would create about 4 (patterned) features. With the holes in a feature pattern, you will gain the advantage of using a Ref Pattern for your bolts (for example)
