Abstract
Rapid prototyping technolony has two steps,decomposing three-dimensional(3D)CAD model and constituting two-dimensional(2D)layer.The information combination in 2D layer is essential for it.Using the development tools of ObjectARX offered by Autodesk Inc,the information of 2D boundary processing after CAD model slicing is described.The closed loops make up of 2D contours.The Linear entity from end to end constitute a loop,which has rotation direction.Based on which,the information of 2D boundary reconstruction is implemented,making the model analysis more convenient.
