I would like to see a few different methods for coming up with a flat pattern of the OD of this part.
Thanks for your time.
Good morning Nick,
Ask me no questions and I'll tell you no lies
Is this what you want? not really clean, but, I think the flat is what you need,
Message was edited by: John Stoltzfus - I see I had an error in the part, should be good now
Here is what I would do. No need to create a new base feature.
P.S. Corrected the surface sketch geometry to bisect the part down the center. (It is skewed in the imported data). Created a SolidWorks 2011 file.
Good afternoon Anna,
When I tried to open your file my SW crashed, so I tried again same thing. It showed me the part and than, bang!!!
Learned that I need to save what I was working on, 1/2 hr down the drain.
Could you check if you have any errors etc...
Also, in the mean time could you upload some pics,
I was able to open Anna's model without any issues. did you save the file to a folder on your harddrive or try to open it from inside the zip?
Good afternoon John,
I tried it both ways and it still crashes,
Are you showing Anna's part??
If it is it's only showing the half part and not the full part that Nick uploaded.
You only need half the part to create the flat pattern. Save out the DXF and mirror in AutoCAD or Draftsight.
I uploaded a SW2011 file. See my prior post for the updated files.
Split the part down the center with a Surface Cut. Then use the straight edge created to Insert Bends.
The issue with Nick's part is that the cut he has defined will not look that that when you roll up a flat sheet of metal. The result of your cut edge will be different depending on if you favor the inside or outside of material.
I think the assembly shows the possible results from a rolled piece of metal. Red is OSM, Purple is ISM. The rolled cut edge will always be normal to the ISM or OSM surface.
Most likely you would want the ISM version and would fill the gap with weld.
Good morning Anna,
Thank you for your veiws
Here I would still lay this part out in one pc for assembly and drawing properties.
Anytime that you add sheet metal features to a rolled pc, you need to select a straight edge, unless you use lofted sheet metal and that is why Nicks part needs to have work arounds to do it in one pc.
