CAD Based 3D Inspection

SITIUS

•Reduce and eliminate the need for 2D drawings

•Unambiguous model representation – eliminate interpretation errors

•Uniform treatment for all types of geometry – prismatic, free-form, simple, complex

•Simplify tolerancing and move towards surface profile

2D vs. 3D

SITIUS

From 2D drawings - 3 daysTo CAD model - 4 hours

To CAD model - 30 minutesFrom 2D drawings - never

Integrated in Unigraphics

SITIUS

•Eliminate model translation

•Dramatically reduce time

•Use 3D solid information

•Access assemblies directly

•Provide 100% accuracy

•Highest level of data integrity

•Eliminate data duplication

•Detect engineering changes

Associative inspection – data stored with the CAD model and linked to the geometry

SITIUS

•Seamless updates
