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. Waje-jiya bawa lissafi, nono nono ƙarfi, da sashe-ga-sashe dangantaka wajen halakayi jiya takaice.

Jiya ƙarfi a korar DXF ya buƙa mai ƙula. Tsarin ta daidai zuwa 16 alamomi nooni, amma yawancin tsarin yanke suna aiki a 0.1mm ko 0.01mm ƙarfi. Saiti korar ya kamata ya saba waje tsarin yanke don watsi jiya ƙarfu da canja lissafi da suke canja alloye banaji ta fraksi na millimeter—isasshe don samar da kasua kadarori a jerin sashe. Ayyukan samarwa na ƙwararru sukan fitar da DXF a tsohuwar siga kamar AutoCAD R12 don samun cikakkiyar dacewa da tsofaffin injunan yanka, domin sabbin sigogin DXF suna kawo nau'ikan abubuwa da tsofaffin masu karanta fayil ba sa iya fahimta.

AAMA Tsarin: Ma'anoni na Musamman ga Tufafi

American Apparel Manufacturers Association ta ƙirƙiri ƙa'idojinta na musayar tsarin tufafi ne musamman don magance gazawar DXF wajen ɗaukar ma'ana. AAMA ba sabon nau'in fayil ba ne, sai dai jerin ƙa'idoji a kan DXF: fayilolin suna ɗauke da bayanai na musamman na tsarin tufafi, kamar sunayen guntaye, girma, alamun yanka, layukan ciki da hanyar zare, ta hanyar layers da alamun da aka amince da su, maimakon a bar su ga fassarar siffa.

Wannan yanar gida da aka fara ya samar da aiki-aiki kasua lokacin da alloye suke wuce gida. Studios jiya kasua sarrafa kasua sa'a kuma aiki-aiki korar gida: AAMA ga tsarin kasua yanke, DXF ko ASTM ga kasua jama'a.

ASTM Tsarin: Sigar DXF da aka Daidaita

ASTM D6673, wanda ASTM International ta wallafa, yana bayyana tsari da aka gina a kan DXF don musayar tsarin tufafi tsakanin tsarin CAD. Ana yawan kiransa DXF-ASTM ko AAMA/ASTM saboda yana bin tunani ɗaya da AAMA: ana ajiye guntaye a matsayin blocks, layers masu lambobi suna da ayyuka ƙayyadaddu, kuma alamun rubutu suna ɗauke da sunan guntu da girma.

Yawancin shirye-shiryen CAD na tsarin tufafi suna ba da AAMA da ASTM a matsayin zaɓuɓɓukan fitarwa daban-daban, kuma tsarin yanka da shimfiɗa da yawa suna karanta duka biyun.

Sarrafa tsabta korar fayil yana buƙa aiki-aiki tsarin tare da waje kasua ƙarfi. Fara da bincike tsarin yanke ƙarfi da tsarin mai goyon baya. Yawancin tsarin yanke na kasua suna karɓi nau'i mara ɗaya amma rana su tare da banbanta fidelity. Buƙata fayil bincike takaice daga kasua yanke da ake takaice: tsarin danjer mai goyon baya, jiya ƙarfu, samomi nau'i hannu, kasua tunkara convention, da metadata kasua ilhamanta.

Jiya tsari haɗi yana samar da shawara shago fito. CAD tsarin suna buƙa asali daban (saba hagu maimakon a gida) da akshin tsari (Y-saba maimakon Y-saba). Saiti korar ya kamata ya saba tsarin yanke jiya asali. Alloye korar tare da Y-saba tsari zuwa Y-saba tsarin yanke ya iso a tare mirga, tare da masu aiki suna shakatawa zuwa ga mirga sashe hannu kafin yanke.

Korar fayil ba da raka'a ayyana da header bayani, amma tsofon bincike tsarin suna rasa header da ka buƙa raka'a sannan. Mara tunkarar yadda 45cm jiki zuwa 45-inchi sarki mulki. Sarrafa aiki-aiki ya kamata ya ture aje ushiku (millimeter) azaman kasua matsakaici tsarin, tare da bayani raka'a bincike kafin fayil sako.

Alaman sha da linye na ciki hannu yana buƙa tsarin-takaice hanya. DXF korar ya kamata ya sai alaman sha a kasua jiya (NOTCH-SINGLE, NOTCH-DOUBLE) tare da daidai lissafi abubuwan (3mm linye sashe ga singles, 6mm ga dubu). Fitarwar AAMA da ASTM suna sanya alamun yanka a kan nasu layer na daidaitacce, amma ka tabbatar cewa tsarinka na karɓa yana karanta nau'in alamar yanka da gaske, maimakon nuna dukkan alamun iri ɗaya.
