What is meant by this?

During volume modeling, a 3D scan is converted into a volume model (CAD format). This is the conversion from STL to STEP. This type of reverse engineering is suitable for components that consist of simple standard geometric elements or complex free-form surfaces.

Which file formats are available?

The prerequisite for reverse engineering with volume modeling is again a 3D scan that is available as a polygon mesh (STL file).

What happens to the data in volume modeling?

Based on the 3D scan, the model is reconstructed in CAD. The resulting CAD model deviates between 0.05 mm and 0.1 mm from the original 3D scan. The standard geometry elements of the finished solid model can be edited to a limited extent with most conventional CAD programs. The free-form surfaces of the solid model can hardly be edited.

Which format will I receive?

The CAD data can be exported as a closed solid model in the following formats:

• STEP (Standard for the Exchange of Product Model Data)
• IGES (Initial Graphics Exchange Specification)
• XT (Parasolid Model Part File)

Is there a target/actual comparison?

Yes, a target/actual comparison is created that compares the original 3D scan with the reconstructed CAD model. Any deviations are illustrated with a color scheme.
