Before using Topology Dataset to perform Topology Check on a Relation, it is necessary to perform Topological preprocessing on the Topology Check data, and adjust the problem data within the tolerance range through preprocessing. Failure to perform Topological preprocessing may result in errors in the results of Topology Check.
The Topology Preproces sing is divided into 2D Topology Preproces sing and 3D Topology Preprocessing.
2D Topology Preprocessing : introduces the 2D Topology Preprocessing mode, including Insert Node, node and node snap, and adjustment of polygon trend.
3D Topology Preprocessing : introduces 3D Topology Preprocessing operation and provides Node Snap processing mode. Currently, this function only supports 3D Line Dataset.
