display tangential edges

[Stefano_68]

Good morning to all,

I have the following problem for which I can't find a solution.
putting on the table a part does not appear all tangent edges, but only some.
You know why? software bug or my incompetence?

Thank you, hello!

e' unbug part software?

to me it never happened that only some tangent edges are visible (when I visualize the hidden lines are too many)however try to control the layer settings maybe changing color to highlight what you see or the settings of the drawing view
