Format, ilk olarak 1990'larda yalnızca 3D içeriği değil aynı zamanda toleranslar ve malzemeler gibi endüstriyel kullanıma özel ek verileri standartlaştırmak amacıyla ortaya çıkan STEP formatının yüksek oranda sıkıştırılmış bir versiyonudur. ISO-10303-21 standardı olarak bilinen STP dosyalarına yönelik standart, ek özelliklerin etkinleştirilmesi için yıllar içinde revize edilmiştir.
STPZ dosyasındaki sıkıştırılmamış 3B veriler, yüzlerden, kenarlardan ve diğer geometrik verilerden oluşan şekillerin bir kombinasyonu kullanılarak metin biçiminde temsil edilir. Belirtildiği gibi, STPZ formatı 3D model alışverişi için bir standart olacak şekilde tasarlanmıştır; bu, dosya dönüştürme yazılımının yanı sıra CAD ve 3D modelleme uygulamaları arasında da yaygın bir desteğe sahip olduğu anlamına gelir.

Sıkıştırıldığında bile, bir STPZ dosyasının 3D düzenleme yazılımına yüklenmesi biraz zaman alabilir, bu nedenle lütfen bu dosyaları düzenlerken ek süre tanıyın.
