]Comment déplacer le point d’origine de hachure plus près de la limite de hachure pour améliorer les performances
Problème : Comment déplacer le point d’origine de hachure plus près de la limite de hachure pour améliorer les performances (CADNET-1340).
Astuces : Pour ce faire, obtenez les entités CadHatch du dessin, définissez les points requis avec Point2D, calculez la distance et dans CadHatchPatternData définissez LineBasePoint pour X et Y.
