Shell CAD Compare Module

Quickly and accurately compare measured shell data (actual) with CAD models (nominal) or mathematically generated meshes.

Note: This module includes all functionalities of the Shell Extension and Shell Topography Modules.

Load actual and nominal data – import measured freeform surface data and compare it with CAD design models or meshes generated from processes such as additive manufacturing.

Pre-alignment tools – align datasets automatically or manually by selecting matching points—particularly useful when working with partial measurements.

Refine alignment with algorithmic fitting – let the software optimize the alignment to ensure the best possible match between datasets.

Visualize deviations – compute and display surface deviations using customizable color scales in the 3D view for clear, intuitive interpretation.

Generate result shells and deviation maps – create output models and use them for further visualization or in-depth surface texture analysis using additional Mountains® tools.
