visibjità board

[stefanodeutz]

Good morning to all,
Today I have an unusual problem: in the images I attach later it can be noticed that in the central view you do not see the outer edge of the piece despite setting the visibility of tangent edges etc.
another curious thing is that when I send the profile dwg file to our supplier sees two parallel curves shifted about a tenth, I start thinking it is a program bug!?
allego file version 2018 sp.4
I thank in advance who knows how to give me advice

Can you train a step?

 

[stefanodeutz]

There he is.

importing the step makes me the right views.
obviously can not be the solution to the problem going through the step.
I still attach my file to you so that if you don't happen the edge you have to think about the settings instead of the model (my doubt is that there is something to do with loft profiling, can't you do it through a series of tangent curves? )

 

[stefanodeutz]

first of all thanks for the answer,
Unfortunately, as in other details the modeling depends on curves generated by a cfd ... that in this case amount from exel, strangely with this size of impellers and (only for a couple of days) creates this problem. I think that in the afternoon I will ask for help explanations and, if they give me a solution (dubito) I will share it in the forum

Could it depend on any update of the video card?

found the "solution"... allego screenshot if anyone can interest
