Creo Parametric - Sketch Mode Unhealthy Practices

[@wydstcroix4215]

Thank you. I have made several of these errors and slowly learned the hard way. I have also picked up multiple features of CREO that are not the main subject of the videos you have made. You use them and I realize "that is very useful". Thank you for these series.

Glad it was helpful!

Hi Dave! Thank you for this health video :) For the creation of hole patterns, I often do it like you with points or with a Pattern feature. However, when the holes are along a rounded shape, the radial and circular centerlines don't appear in the drawing (even with Show Model Annotations feature on Pattern feature), whereas with a radial Pattern feature, they do. I then have to draw a layer sketch for the axes... Do you have a trick to make those centerlines appear when repeating by radial points? Thanks a lot to ​@Creo Parametric

[@CADPLMGuy]

Honestly, I’ve never been passionate enough about drawings to pay that much attention to the nuances.

Regarding the last sketch tenick, with this explanation a lot of my problems makes sense now!

[@CADPLMGuy]

Glad this helps. Yes, using the Project and Offset Edge commands to external references leads to a whole host of problems if the original model isn't in session, gets renamed or lost, or you're trying to make modifications later... If you do use those commands, you can also remove the edges from your list of Sketch References and have the entities be dimensioned to local references. It won't be parametric but it will avoid the other reference issues.

Another in topic question please, When you have the main assembly then create a new subassembly, activated the new subassembly and you want to assemble a part. Is good practice to reference datums in the main or subassembly. If the subassembly is there any way to not show the other datums? I know that the active datums have more gray color than the others but with big assembly's it's frustrating and difficult to locate.

[@CADPLMGuy]

Thanks for your question. Ideally assembly constraints should be limited to the assembly in which a component resides. In the scenario you describe, you should reference the datums in the subassembly, not the main assembly. Otherwise you can have issues if you retrieve the subassembly on its own without the main assembly in session. I usually open the Layers dialog box to turn the display of datums off in the main assembly or any other subassemblies that aren't active. Let me know if you'd like me to put together a video to demonstrate this. Thanks for watching and commenting! (Seriously, comments improve the videos' rankings in the KZbin algorithm.

Great Video, Thank you.

In my company we have only the license for Design Essentials, which does not include Top-Down Design. It means the functions of copy geometry or publish geometry cannot be used. They are greyed out. Any good walkaround to this issue? Thanks in advance

[@CADPLMGuy]

Not really.

[@tiagofigueiredo2848]

Nice video. Can you make some video, using the resolve mode for resolve the errors in models?

[@CADPLMGuy]

Tiago, short answer: yes. Longer answer: I created a presentation on Resolve Mode 15 years ago and it kicks butt. I wrote the chapter on Resolve Mode for Tristar's Pro ENGINEER Quick Reference Guide. Resolve Mode is a subject near and dear to my heart, and the only reason I haven't done a video on it yet is that I want to make sure I do it justice and spend considerable time planning and preparing.

[@TananBaboo]

I’ve seen all of these. So painful to see. Thanks for making this video.

So I've been told to not use an extruded hole in place of a hole feature, but I have never been told why. Can you explain why this is bad?

[@CADPLMGuy]

I cover that specific example in my Design Intent video and book. The answer is... it depends on Design Intent. For example, if it's likely that the hole might need to become a slot, then a sketch and extrude would be preferred. But if the likely changes are things like counterbore, countersink, dimensioning scheme, standard hole sizes, etc., then the Hole feature would be preferred.

[@tednugentlives]

You have more end treatments, depths, and edge options vs. a plain hole. Anytime you have to do a complete feature redefine sketch to make a simple tweak, you can blow stuff up ;) . Inventor uses this type and its bad.

[@CADPLMGuy]

@@tednugentlives Yes, SolidWorks essentially has two sketches for a hole, one to locate, one to define the shape. If you're trying to create something that's going to be a hole in the real world, the Hole feature in Creo gives a lot more flexibility for making changes than a sketch.

[@marcusblessing]

@@CADPLMGuy @x_unt plus there's the added benefit of the parametrically generated hole callout notes for the hole feature vs a simple extrude when using the "show model annotations" tool in drawing mode. Having that note dynamically linked to the feature saves lots of headaches of trying to remember to update a manually typed out note as a design matures/changes over time.

Hey i need a help on how to convert .stl file or facet into solid so that i can modify in creo

[@CADPLMGuy]

You can try using Save As > Save a Copy to export it to a Shrinkwrap to get a solid, but it will be very difficult to modify. The Reverse Engineering Extension (REX) - which by the way is very expensive - does have some functionality for manipulating facets, but it's probably been more than 10 years since I've touched that module.

[@jatinsharma9359]

No prob so i have another option I'll ask my frnd to do it in catia its simple in that

[@CADPLMGuy]

Jatin, do you have the file in a .OBJ format? If so, you can import it into a Freestyle feature.
