The most common reason I've found is to avoid going back and changing the model. It's a shortcut - and one of the worst things you can do on a drawing.
People used to do this in Autocad because changing the geometry was sometimes painful. Note that I also forbid this practice. If I take the example in the video and change the fork dimension, the radius won't match anymore and the guy who will code the CNC will sure have a fun time.
@@CADPLMGuy but overriding need to be done if u wanna simplify dimensions by giving tolerances..i don't see any wrong in that cause the middle value of tolerance will be the exact valve we require
I actually don't like the term "Best Practices." I find it gets overused to the point of being meaningless and that people use it without concrete data to back up that it's actually best. I prefer the term "healthy practices." But I really feel that the techniques I show in this video are the worst. Thanks for watching and the feedback, Praveen.
With a lot of herited geometries/dimensions, in extreme situations there will be no model dimensions, while for manufacturing the geometry needs to be defined on the drawing (there have to be dimensions), so this 95% rule of thumb is misleading in my opinion. (of course if this is a stand alone part with no dependencies maybe OK, but in an everyday situation the parts are parts of assemblies).
Is there any option to copy/paste a subassembly with its constituent parts and their drawings/formats into a new folder. I know that "save a backup" option of a subassembly drawing copy its parts and the drawing only of that particular subassembly. What about the drawings of the constituent parts?
You can do this in Windchill. You can use Collectors to grab related CAD models, drawings, WTParts, and so on, when performing Save As operations. If you're not in Windchill, you probably have to do this manually in Windows Explorer.
@@CADPLMGuy Thanks for the reply. Please ignore my email about the same query. I have another question not directly related to creo, it is about GD&T. Can we use gd&t in assembly drawings in which parts are assembled by hole/shaft based fits or using fasteners?
@@CADPLMGuy 5, 4 & 3. Since watching this I'm down to one which is the BOM creation but I am working on that. The issue I have is how badly the parts are named on windchill at work. If I'm creating a simple tool from scratch I can use auto BOM creation.
