Training course - Shape Healing

Overview
On completion of this course, participants should be able to use the main capabilities of Shape Healing component of Open CASCADE Technology.
They will learn how to:
- analyze-detect problems within Open CASCADE Technology shapes as well as perform advanced analysis (tolerances, free boundaries, etc)
- fix and repair the detected irregularities
- upgrade and customize - modify the Open CASCADE Technology shapes to respect specific requirements (continuity, B-Spline representation, etc) and sewing
- handle shape processing : mechanism of creation of the sequence of fix and upgrade operations controlled by the user at run-time

Prerequisites
The participants will need to have solid knowledge on Open CASCADE Technology topological data structure.
They must be familiar with all fundamental notions of Open CASCADE Technology.

Introduction
