Extracting outline edges of a sewed sheet. 3

[vasinka]

Hi, I am new to forum and NX8. So happy I found this forum. I have searched the forum have not found an anwer to my question so I am starting new thread.

I am trying to find a command that would create curves ONLY from the outlines edges of a sewed sheet, IE edges that are not sewed to (or touching) any other edges/faces.

I have sewed multi face sheet into one sheet. It contains multiple faces therefore multiple edges inside of sheet. When I use 'extract edge' command followed by 'edge curves' option, I can manually go around my sewed sheet and select the outside edges, However I feel like there should be automated command that would extract curves only from the edges of the sheet that are not connected/joined to other face.

Thanks

OK, try going to...

Insert -> Associative Copy -> Extract Geometry...

...and set the first option to 'Composite Curve' and then set the 'Curve Rule' on the Selection Bar to 'Connected Curves' and select any of the outer edges of the sheet body and you should get what you're looking for. Note that if the selection didn't actually get you all of the 'outer' edges, you may need to toggle on the 'Boundary Edges Only' icon to the Right of the 'Curve Rule' item and try it again.

Note that this 'Composite Curve' can be created either associative to the original surface or not (that option can be found in the 'Settings' section of the dialog).

Thanks for reply Jhon.

I encountered another problem.

I dont have "Extract Geometrty" option under Insert->Associative Copy. :/ Instead I have "Extract body" but it does not give me options that you talk about, so it is a complitely different command.
I used 'Command Finder' to search for "Extract Geometrty" and it still didnt find it.

Sorry, I was running NX 8.5 instead of NX 8.0. That being said, while the 'Extract Geometry' function (which really collected into a single dialog several existing 'Extract' functions) was not implemented until NX 8.5, but as I implied some of those functions are already in NX including 'Composite Curve'. You can find it at...

Insert -> Associative Copy -> Composite Curve...

...which works just like I described in my first post.

Hi,
Just an appendage to what John said.You can utilize composite curves (sheet edges to get the associative extracted edges (if you wish some interior edges also)).I am attaching a picture herewith.

IT WORKED!!!

You guys are genius...

THANKS

So what are you doing with the extracted curves ?

I just needed End Of Part (EOP) curves in place before I altered the part for manufacturing.
