The 3D-Tool Viewer works with graphic visualization data (MESH) and an export is only possible in visualization formats. The 3D-NativeCAD Converter only works with exact 3D CAD data (BREP) and enables their conversion. The 3D-NativeCAD converter can only be used with a Premium license.

Import Options

The quality of the visualization and thus the amount of data can be adjusted when importing 3D CAD models into the CAD viewer. 3D-Tool Premium also offers the option of loading the graphic visualization data from native CAD files. This means that the 3D-Tool viewer also opens large assemblies from CATIA, Siemens NX, SolidWorks, SolidEdge, Creo and Autodesk Inventor on ordinary PCs.

For native 3D models from Creo and SolidWorks, any existing "simplified representations" or "configurations" can be selected in the Premium import of the Viewer and the Converter.

The 3D NativeCAD Converter guarantees very high quality when converting CAD models into 3D exchange formats such as STEP and IGES through automatic HEALING. Assembly models can be simplified by specifically selecting parts and subassemblies during conversion. When converting it is also possible to switch off and on the points, curves and hidden elements contained in the models.
