DXF: Tsarin Musayar Kasua

DXF ya fito ne a 1982 azaman maganin Autodesk don musayar zane mai kuzari tsakanin aikace-aikacen CAD. Abubuwan da ta yi kasance na lissafi (layi, bauguna, polylines) azaman bayani ASCII ko binary, tare da shi karantawa a gida da jiya da lokaci. A sarrafa alloye, DXF yana aiki azaman tsarin mafi gida-common-denominator lokacin da tsarin ba sa wanda na gida fayil mai goyon baya ga kowannen ɗaya.

Tsarin ta shirya bayani zuwa sashe: HEADER (saita jiya), TABLES (alamomi ma'anar, kadarori jiya), BLOCKS (abubbuwan da za a yaɗa), ENTITIES (jinya ainihi) da OBJECTS (bayani ba na zane). Sashe na alloye korar azaman rufaffiyar POLYLINE ko LWPOLYLINE samomi, tare da kowannen gitsa sha wurare X-Y a ƙarfin da aka niyata. Alaman yanke su zama POINT samomi ko linye gajeriyar LINE, jiyoyin yanke korar azaman linye da soyayya, da linye na ciki (ɓatuna dart, alamomi taba) kiyaye azaman tsarewa jiya LAYER.

Abubuwan da ake amfani DXF yana aje jiya da gami danya. Kowane jiya na CAD kasua tun 1990 karanta da rubuta DXF fayil. Tsarin noma da na lissafi yana ba wa kumburin sauran bayani kira da lilo a lokacin da ka shigo saida takaice. Duk da haka, wannan gami ya zo tare da kuɗi: DXF bawa ba ilimin azanci game da alloye-takaice kadarori. Alaman sha korar azaman lissafi wuri, amma aiki (alaman daya, alaman biyu, alamoni haɗi) ya buƙa ko jiya kasua tunkara convention ko sa'a sa'a labari fata.

ASTM Tsarin: Alloye-Takaice Azanci

American Apparel Manufacturers Association ta bada bayani gida takaice na sarrafa alloye a 1993 musamman don tunkarar DXF na azanci iyaka. AAMA fayil a ciki alloye-takaice metadata: suna sashe, bayani girma, nau'i alaman sha, aiki na linye na ciki, da nono nono azaman bayani da aka tsara maimakon jiya ilhama.

Takaice na AAMA ta kaddara tsari da soyayya. Kowannen sashi alloye korar azaman PIECE samomi tare da a ciki BOUNDARY (yanar gida), INTERNAL (linye gina), da GRAIN samomi. Alaman sha suna ɗauka TYPE kadarori (daya, biyu, kasua, V-alaman) maimakon da ita buƙa durkamewa tunani. Asalinsa jiya su zama lambar ATTRIBUTE a ƙofarin sashe, ba da damar dijital offsetting a lokacin shakatawa. Bisa ga bincike na Jigon Kasua na 2022 na alloye kasua 500, AAMA fayil matsakaicin 40 kashi ƙananne fayil tsarin DXF daidai koƙwara saboda metadata damje-damje da raguwa lissafi sarari.

Abubuwan da ake amfani na tsarin yana kiyaye niyata gina ta yada tashar sarrafa.

ASTM Tsarin: Ilimin Kayan Haɗi

ASTM D7297, wawa a 2016 ta hanyar American Society for Testing and Materials, yana wakiltar sabon tsarin musayar alloye da aka ture. Ba kamar DXF jiya noma ko AAMA sarrafa jiya, ASTM yana haɗi ilimin kayan directly a fayil alloye.
