Function Overview

The CAD-Viewer and Converter from 3D-Tool has useful tools to analyze 3D models without CAD knowledge. At the push of a button, 3D-Tool provides the dimensions, the surface area and the volume for all parts of a model. Distances, angles and radii can be measured with simple mouse clicks.
