Il formato STP (noto anche come STEP) è un formato di file 3D comune utilizzato all'interno CAD (Computer Aided Design) cerchi e viene utilizzato per archiviare complessi Modellazione 3D dati in un formato standard che può essere scambiato in modo affidabile tra applicazioni CAD e di modellazione 3D con facilità.
Il formato è emerso per la prima volta negli anni '90 con l'obiettivo di standardizzare non solo i contenuti 3D ma anche dati aggiuntivi specifici per l'uso industriale, come tolleranze e materiali. Conosciuto come standard ISO-10303-21, lo standard per i file STP è stato rivisto nel corso degli anni per abilitare funzionalità aggiuntive.
I dati 3D all'interno del file STP sono rappresentati in forma di testo utilizzando una combinazione di forme costituite da facce, bordi e altri dati geometrici. Come accennato, il formato STP è stato progettato per essere uno standard per lo scambio di modelli 3D, il che significa che ha un supporto diffuso tra le applicazioni CAD e di modellazione 3D, nonché i software di conversione dei file.

A causa del formato basato su testo, i file STP possono diventare molto grandi quando si salvano dati 3D complessi nel formato. Anche il caricamento dei file STP nel software di editing può richiedere del tempo, quindi ti preghiamo di concedere più tempo durante la modifica di questi file.
