Importing 3D Models and CAD Files

Jig Workshop supports importing .OBJ files on free subscriptions and STEP and STL files with a Jig Workshop Pro subscription.

Importing OBJ Files

Press the Add Object :menu_addobject: button on the left menu to open the object library.

Select the blue icon to ‘Use my own 3D Objects’.

Select your object and load it into the platform.

You will be able to customize and explore your 3D object in the Jig Workshop, and when you’re ready you can tap on the AR Mode :menu_armode: button on the left menu to view your Jig in Augmented Reality.

OBJ UV Map Support

One of the reasons the .OBJ format is so versatile is that it supports the use of UV Maps. This means that if you’ve created a UV map you will be able to add your own textures to your models inside the Jig Workshop. You’ll find the texture options in the Colour :toolbar_colour: button on your toolbar.

For a more detailed look at importing textures you can go to our tutorial on Adding and Removing Textures.

OBJ Export Settings

OBJ files can be exported from many popular 3D modelling software programs. For free Workshop accounts:
  • .obj files need to be less than 30MB each, roughly 300,000 triangles.
  • Multiple mesh objects can be exported as a single .obj file. They will stay separated in Jig Workshop.
  • Reset transforms on your mesh objects.


  • Model dimensions of 8,8,8 blender units are a good average size to view your model in augmented reality.
  • Use these settings when exporting a .obj file from Blender:

3DS Max

  • Model dimensions of 120, 120, 120 Max units are a good average size to view your model in augmented reality.
  • Currently models need to be rotated 180 degrees before exporting to face the right direction in Jig Workshop.



  • Model dimensions of 12, 12, 12 Maya centimeter working units are a good average size to view your model in augmented reality.
  • Currently models need to be rotated 180 degrees before exporting to face the right direction in Jig Workshop.


Exporting Tips

  • Build your objects at or near 0,0,0 to have them show up on the Jig Workshop platform.
  • Rotate your object(s) so they face the front camera.
  • Jig Workshop materials don’t support “backfacing” polygons. To avoid holes in your mesh, build polygons to cap any holes within your mesh.
  • Object transforms are aligned to the world when imported into Jig Workshop. If you need your objects to have a specific transform axis, import your object in Jig Workshop with no rotation, then rotate them.

STEP Files

STEP files are a widely accepted format for exchanging 3D product model data in the computer aided design (CAD) industry. The main 3D software packages that support exporting STEP files are professional manufacturing programs like SolidWorks and Fusion 360.

The Jig Workshop Pro subscription allows industry professionals in machining and manufacturing operations, to bring their 3D designs straight into the Jig Workshop to view them in Augmented Reality.

To provide a seamless experience, as a part of our import process your models scale will automatically be adjusted to fit the Jig Workshop scene, and any inverted normal’s will be corrected.

Importing your own STEP file is the same process as importing any other object file.

Tapping on the Add Object :menu_addobject: button in the left menu to open the model library.

Then pressing the Blue Button button, you’re able to select your chosen STEP file.

Once your STEP file is loaded in you will be able to edit it like any other model. You can scale and position it, add materials, and even select and edit its Sub-objects. Just press on the Object Mode :toolbar_objectmode: button on the tool bar to enter Sub-object Mode :toolbar_subobjectmode:

STL Files

The STL file format is well known for precise 3D printing. Many 3D software packages support exporting to the STL format, such as CAD, Maya, Blender, and Rhinoceros 3D.

Here is an example, using Blender.

Important: the STL file format does not keep UVs or support sub-objects.

Before importing an STL file to Jig Workshop make sure you have it saved to your device. Here are some ways to transfer your files into the device.

  • Send them using email.
  • Send them to your iCloud, Google drive, etc.
  • Download from the Internet.
  • Send them using chats (for example Slack).
  • Send them using Airplay, Bluetooth.
  • Download from your computer using a cord.

Import STL file to Jig Workshop

To import your STL file to Jig Workshop go to :menu_addobject: then press the big blue button

Blue Button and choose your STL file on the device.
