Hi, i have a igs file of a ship hull. I must modify the leading edge. I have created the new leading edge geometry but there are two different geometry entries : the imported and the new piece made with icem. I think these 2 different geometry entries is crucial for mesh generation process. I realized a mesh but there are many hole and not continuous parties. I made a geometry and build topology but no result. I'd like to make a fusion of two geometry entities and make a single geometry, how can i do this? Thanks for your help
