]Cara memindahkan titik asal hatch lebih dekat ke batas hatch untuk meningkatkan kinerja
Masalah: Cara memindahkan titik asal hatch lebih dekat ke batas hatch untuk meningkatkan kinerja (CADNET-1340).
Tips: Untuk melakukan ini, ambil entitas CadHatch dari gambar, setel titik yang diperlukan dengan Point2D, hitung jarak dan di CadHatchPatternData setel LineBasePoint untuk X dan Y.
