This ensures all major CAD systems can generate STL files that produce high-quality prototypes. The software now repairs most gaps in CAD models. For more serious errors such as missing surfaces, it produces a message summarizing the problem. The software also removes duplicate triangles and nodes, triangles with poor aspect ratios, intersecting triangles, and triangles having more than one other triangle sharing an edge.
