Top down parts to Sheetmetal

[bretonh]

Hello,


I have a part that was created using some copied geometry from an assembly. I would like to convert that part to a sheetmetal component so that I can do a flat pattern, but Pro/e won't do it.


Is this impossible to do?





Thanks.

It's unlikely that the copy geometry is preventing the conversion to sheet metal. more likely is that the geometry itself prevents conversion. Without more info, I'm not sure we are going to be able to help. Can you upload a model or provide screen shots?

Here is the model

It's your countersunk holes. I suppressed them and it worked fine. I think they'll need to be after the conversion.

If it were me, I'd do the conversion after the initial wall geometry then re-create all the openings with sheetmetal cuts. At least re-do the obround one that intersects the bend so you get an accurate cut through the bend.

Thansk alot!


Very helpfull!

I did a custom class for a sheetmetal manufacturing company several years ago. They had parts from their customer who used unigraphics, solidworks to model sheetmetal parts but the customer refused to use the sheetmetal module instead modeling with thin walls. Most parts would not convert over.Basically the old guy at work that this sheetmetal sux models using solids....

workflow block diagram looked like this:
-import iges
-solidify
-convert

(if the proe part does not have all uniform wall thickness then the part will not convert. You have to fill the Countersink holes in the iges file before you convert to sheetmetal in Pro/E)

-fix with surfaces in the IGES file to have nominal wall thickness
-solidify
-convert


-fix that issue
-solidify
-convert
-flatten

(if the new converted part converted correctly then try the flatten. If the proe cuts fit incorrectly on ruled surface then the cut will be normal to the sketch plane and not normal to the ruled surface)
