When two bodies with different topologies need to be connected by a third body, we cannot use skin\/Loft. Another approach can be used as in the Workbench project in attachment. With this approach, we create lines between both bodies. Then we use this lines to create the side surfaces of the third body. We also create the top and bottom surfaces of the third bodies. Finally we use a body operation ‘Sew’ to create the solid body with the different surfaces. We use the features: o Concept > line from points o Concept > surface from edges o Create > Body Operation with the option ‘Sew’ and we select yes for the option ‘Create Solids’<\/p>\n
