STEP

STEP (short for "Standard for the Exchange of Product model data") is a popular exchange format connecting the world of electronics and mechanics. Usually it is used to share 3D models between users with different CAD systems. STEP goes beyond the simple exchange of gemoetry like DXF and IGES. You can integrate all forms of CAD data models (wire, surface and volume models) in the geometry description.

3D Design Options

With PCB-Investigator, you have the ability to obtain a realistic 3D view.

This guide explains how to create accurate 3D views and ensure their inclusion when exporting to various formats such as STEP, OBJ, and WebGL. To do so, follow these steps:

    1. Step 1: Open PCB Investigator 3D and import the desired PCB layout into the program. Ensure that the layout is imported correctly and is free of errors, as it serves as the foundation for the 3D visualization.

    2. Step 2: Activate 3D mode You can switch between 2D view and 3D view in the bottom left corner. Alternatively, you can navigate to the View Settings menu where you will find the 3D plugin.

      Here, you have three options to choose from:


      • 3D Board: Displays the entire board in 3D with several selection options. You have also the possibility to export in this option.
      • 3D Selected: Shows selected features, drills and components in 3D.
      • 3D Setup: Provides setup options for the 3D view. Read more in the next step.

       

       





    3. Step 3: In the view settings, you can adjust various parameters such as DPI resolution, viewing angle, lighting and background. Experiment with these settings to achieve the 3D view you want The given picture shows you an important option - The Real Part Library - for exporting the 3D design as .obj or .stp file.
      • Import Unit: Allows you to change the unit of measurement.
      • One Obj/Stp-File per: Provides options based on Part Name, Package Name, or Reference for generating individual .obj/.stp files.
      • Library Up Direction: company up direction (X, Y, Z).
      • Center to Cmoponent: Defines the component position as either center or Insert Point (the yellow point on the component, in 2D view as gerber point).
      • Add IPC Angle Correction: Basically, this function is always enabled if your library is ipc comform (e.g EPL library).
      • Download step files: downloads all step files with stepfile path property.
      • Use Design Library: With this option it is always copied in the user directory.
      • Use Local Library: This option is looking in a local library. However, if there is no access, then copying is not possible.

 

3D Export Format

If you wish to export your 3D design, you have the option to do so in STEP, OBJ, and WebGL formats.

 

  • For the STEP format:
    Generates an .stp file in your specified directory. First you have to set the 3D Step File Path:

 

  • Right-click on the selected element and choose "Edit" from the context menu.
  • In the Edit menu, navigate to the 3D option.
  • Within the 3D option, you can set the step file path by specifying the directory where you want the .stp file to be saved.

  • For the OBJ format:
    This format outputs multiple files. You receive an individual image file for each component, along with an .obj and an .mtl file in your directory.

 

  • For the WebGL format:
    Produces an HTML page and opens it. There, you can view your 3D design. The following picture shows the HTML site.
