Solidworks and Sihouette edges |
|
|
Why is it that a simple parts like an O-ring can't be detailed in Solidworks
without having to resort to splitting the surfaces?
I create a simple O-ring with a revolve and it won't let me pick any of the
edges in the drawing. What am I missing? It's such a pain to have to go
through anything round splitting edges so you can detail. Then you have to
go though the drawing and high all the unwanted split edges that end up
showing up in other drawing views. It Sucks!!!

make sure sketches in your drawing are set to visible & then show the sketch
from the feature that you wish to dimension & to some vertex or arc in your
sketch at the drawing & then hide that dimension after your done.
Hope that helps

Use a section view in your drawing instead of adding an unnecessary
split line to your part.

I agree with you. There are always work arounds but you would think that
such a simple thing would be possible. Every year we get a new releases with
even more ways to do the same things but the basics are often ignored. Rant
over! Roger

Guy's thanks for the idea's. I do use these workarounds already and have
some others like copying and pasting a drawing views make the edges become
selectable. Sometimes though none of these seem to work or be a good
choice.
I guess I was just hoping I was missing something rather basic.
Doesn't it just seem like this is such a very basic function in a CAD
package? Shouldn't this just "work" in a Super-duper high-tech, program like
this? These are the kinds of things I wish they would fix before adding any
more bells. |

Last I worked on UG (c. 1999) and Pro/E (c. 2001), the same issues were
apparent when detailing O-rings. Pro/E usually wasn't as big a problem
as we usually used the model dimensions.
Maybe that's another possibility: insert model dimensions into the
drawing. |

Or show the sketch used in the revolve to create the oring and
dimension that. |

I doubt abc needs the work arounds, its the lack of basic functionality
that's the point here. |

I think "lack of basic functionality" is a bit harsh. I noted
challenges with detailing O-rings on different CAD systems.
Try to imagine what the program is trying to do. An o-ring is a single
toroidal surface. No breaks, flats, or edges. Every silhouette
actually wraps around the entire part, making the logic for selection
and attachment of dimensions inherently ambiguous. Computers hate that. |

When working with 3d modeling programs, detailing often needs these
workarounds. It's the same in any cad package. I often have to show
sketches for detailing purposes in UG. Some programs do a little better
but none will detail like Acad cause in Acad it's not real. You are
simply drawing a circe to make the o-ring and thus it dimensions fine. |

This is one of the benefits that Solid Edge has over other modelers in
drafting. It creates associative lines/arcs/circles/splines in the draft
file, so you get the best of both worlds... 2D data like ACAD and model
associativity. Your dreaded "o-ring" is apiece of cake to dimension in
Solid Edge.

Catia V4 created views that way as well (Not sure about V5).
Problem there was large assemblies took hours to rebuild all the
drawing views. The upside was you modify the lines and arcs like
Autocad, though a rebuild would undo it.
That's one reason we switched to Solidworks from Catia. I benchmarked a
moderate size assembly. Catia took 15 minutes to update just 3 drawings
views. Solidworks took maybe 15 seconds. |

That is one thing I missed in SE. You had to tell it to fix the
drawing. When it did it marked any changed dimensions with a REV
symbol. I didn't always want that. But it did help in recognizing what
changed. SE also didn't always bring in all the dimensions.
Ken is right though. SE drawings can stand on their own and can be
opened without the model. |

No need to pick sihouette edges .
When creating the part model, place the dimensions approx where you
would like to see them in the drawing. In the drawing use insert "Model
Items - Dimensions" selecting the "use dimension placement in sketch"
option. It may look a mess at first but it does not take long to sort
out what is needed/not needed, I find it best to dimension one view at
a time using this method.
Why manually input a dimension when it is already there? less chance
of missing one or picking the wrong edge/point and you get the
funtionality to change the model from the drawing.
Just my two pence worth.

Well if you save drawings in the "detached" format, you can open them
without the model. Of course the file size blooms when you do that due
to it storing all the edge info.
How large aer Solidedge drawing files in comparison? |
