Technical note

How STEP and PDF differ in practice

PDF holds pages, which makes it a natural container for a review of a model from several sides. With Create multiple frames switched on in the 3D formats loading settings, each step of the turn becomes its own page, so one file shows the part from every angle you set and opens on any device. For a technical sheet, Create 2D projection gives the isometric, top, front or side view as a line drawing. Without further settings, a STEP assembly converts to a single PDF. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one PDF per part.

3D Workflow

From 3D model to PDF

Turn STEP models into PDF sheets for design reviews, quotes and archives. Set the views once, and every model in the folder comes out the same way.

  • Show the model from several angles in one PDF: each step of the turn becomes its own page
  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Pick up new models automatically with Watch Folders
