Rhino shows me not naked edges, STP files doesn´t

Hi. I prepared a model in Rhino to export to SW. The file does not show any naked edge. I exported the file from Rhino to STP. When I open the STP in Rhino it shows naked edges.

I am not sure if this has to do with the export options. Do you know how to solve this issue?
Thank you

it depends on each case but check the edge tolerance before exporting.
if the edge tolerances are too big. they could break later.
in other cases could be just the conversion.

Hello - if you select the original object in Rhino and run the What command, what does that tell you about the edge tolerances ?

Hi ! Thanks so much for helping!
It says
Edge Tolerances: 0.000 to 0.000
median = 0.000 average = 0.000

The whole dialog box says this:
Geometry:
Valid polysurface.
closed solid polysurface with 96 surfaces.
Edge Tally:
2 seam edges
16 singular edges
230 manifold edges
= 248 total edges
Edge Tolerances: 0.000 to 0.000
median = 0.000 average = 0.000
Vertex Tolerances: all smaller than 0.000001

Any idea how to check that? and fix it?
Thank you

there is a test command called _testMarkOTEdges which will make dots indicating edges which are far from file tolerance. in that case it doesn’t seem to be the problem. maybe is just for the conversion.

Hi Bruno - can you please post the Rhino object or send to tech@mcneel.com, with a link back here in your comments?
