3D Models
Processing of 3D model files and generating Model Targets may take anywhere from a few minutes to a few hours, depending on the size and complexity of the model.
3D models are digital representations of physical objects in your environment.
For information about working with 3D models and Model Targets in Vuforia Editor, see the following topics:

Supported File Types
Single-file formats:
.stp or .step (AP203, AP214, and AP242; geometry only)
.jt (up to 10)
You will be required to select a unit of measurement for CAD file formats that do not already contain a unit (for example, .stl and .obj files).
Keep in mind that if the incorrect unit is selected when uploading a 3D model, it could result in issues with point of interest markers and the model in Vuforia Vantage.
Multi-file formats:
CATIA v4 from 4.15 to 4.24
CATIA v5 from R7 to R30 (v5-6R2020)
CATIA v6 R2010x to R2013x, R2015x, R2016X, v6 2020X
SOLIDWORKS as Pack & Go (.zip files from 1999 to 2019)
Pro/ENGINEER, Creo from Pro/E 2000i to Creo Parametric 6.0
Creo 7.0
NX UG15.0 through NX12.0.2.9
Solid Edge 10 through 2019
Multi-file formats must be imported as a .zip file where the .zip file name must match the name of the top-level assembly.
Physical Object Recommendations
Vuforia Instruct uses Vuforia Engine model tracking. Therefore, the following guidelines should be followed to ensure successful tracking:
PTC does not recommend using CAD for an object that is larger than roughly the size of an SUV.
Physical objects must have the exact same shape and size as the 3D CAD model.
Physical objects must:
Be geometrically rigid (that is, they cannot be malleable)
Present stable surface features
Physical objects must not change state during the procedure, so make sure that the product state matches whatever state you want to start your procedure at exactly. For example, parts cannot be moved, removed, or added during the procedure.
Some variation in surface appearance is required to distinguish the object (for example, plain surfaces such as all white or all black may not work well).
Geometric complexity is key to distinguish an object from other shapes in the environment (simple shapes such as cubes, spheres, etc. may be easily confused with other objects in the area).
We recommend avoiding the use of symmetric objects, as the Model Tracker won’t be able to differentiate its sides.
