Product overview & positioning reminder
Purpose/scope of the product
CATIA - Quick Surface Reconstruction 2 (QSR) easily and quickly recovers surfaces from digitized data imported with CATIA - Digitized Shape Editor 2 (DSE)
Targeted markets/processes/customers
Installed Base CATIA V4 CGO : QSR do surpasses CGO Installed Base STRIM, EUCLID Styler : QSR surpasses it in productivity Sub-industries :
Powerfit technology allows to recover the entire shape with few surfaces boundaries definition. Direct product of trimmed surfaces with boundary constraints (Tangencies, ...) Product of not inert adjustable geometries (like cylinders, cones, fillets, ...) can be updated by modifying their radius, length, etc.

Selection on digitized data
Hierarchical selection: Points, scans or grids, digits (in case of digitization in multiple shots) Trap selection: Rectangular Polygonal Spline Capable of managing 3D trap by modifying the depth
Several types of curvature : Absolute, Mean, Gauss Minimum, Maximum Curvature or radius mode On-the-fly dynamic display of value on polygon (to find fillet radius) Iso value can be defined by picking on polygon Filtering of noisy result (scan) Output : scan (iso value) or subcloud (pickable)
