Convert Your 3D Mesh/Model STEP Files to IDTF

to

Our free and fast tool will convert most 3D mesh or STEP (STEP-File) model files to a standard IDTF (PDF With integrated 3D Models) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing.

To convert your STEP file click the Upload button above and select the file to convert. Once selected, the file will be converted to a IDTF file and will ready for download shortly afterwards. For more information about the STEP to IDTF conversion process see the conversion information section below for more information.

File format information for STEP to IDTF

Extension: STEP

Full Name: STEP-File

Type: 3D Model

Mime Type: application/octet-stream

Format: Binary

Description

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STEP files are text-based formatted files containing one instance per line.

Although STEP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.

STEP Notes

STEP files when imported will be converted to 3D geometry comprising vertices and faces. If the STEP file contains color information this will be converted where possible.

Supported Features

  • Mesh geometry
  • Mesh colors

Extension: IDTF

Full Name: PDF With integrated 3D Models

Type: 3D Model

Mime Type: text/plain

Format: Text

Description

The IDTF file format is a bespoke format that enables interactive 3D content to be embedded within a PDF document. Currently only Adobe Reader and PDF-XChange Editor are able to render PDF documents that contain this 3D content.

IDTF files are a simple text-based format containing 3D geometry defined using vertices and faces in a structured hierarchy. Prior to importing the IDTF file to the PDF it must be converted to a U3D file format using one of the free applications such as IDTFConverter.

IDTF Notes

Currently only mesh geometry will be carried over from your source model to the final IDTF file for download.
