j’exporte mon travaille dans CREO Paramétrique et Des trous traversants n’apparaissent pas, car les sommets des lignes verticales ne sont pas jointes.
Comment faire autrement ?

Hello,
I export my work in Parametric CREO and Through holes do not appear, because the vertices vertices are not joined.
How to do otherwise?
