ʻO ka hoʻonohonohoʻana i loko o VDG P690
Vdg p690 Hoʻopili i nā mea kūʻai aku i nā mea hana i loko o nā'ōnaehana hoʻohuiʻelua:
- ʻO ka heluʻana i ke kāʻeiʻana i nā helu Tolerance (DTTG 1-16) No nā hiʻohiʻona laina, and
- Geometrical candings butlerance (Gctg 1-8) no ke ano, Kaniona, a noho.
Pau, ʻO kēia mau helu e hōʻike iāʻoe e kuhikuhi pololei i ke kokokeʻana i ke kohoʻana i kāuʻano e like me kāu, Me kaʻole o ka heleʻana i nāʻae match.

Dctg e wehewehe i ka hoʻokaʻawale loaʻana no ka hoʻokaʻawaleʻana no kahi dimension i hāʻawiʻia.
E wehewehe ana i nā mea i hanaʻia i nā mea e like me nā hiʻohiʻona e like me ka lōʻihi, nā diameters, nā laulā, a iʻole nā mānoanoa ma nā'āpana.
Ua pili pū me ka CT (Kāhea aku) 'ōnaehana pae, Ke hele mai nei mai CT1 (ʻO ka hana paʻa) i ct16 (ʻO ka hapa nui).
