Hi everyone
I am new to Rhino and want to print the attached model - to do that I need to separate out the individual parts. I have been working on selecting all the surfaces of each part and grouping them, but it is very laborious and easy to pick up bits I don’t want. I am assuming there must be a function that looks at a mesh and finds the extremities and then selects all surfaces within that boundary. That would allow me to select for instance one of the hangers and group it and move it out as a separate part to output as a STL file. I tried using boolean split and boolean difference to no avail. Would love some guidance - thanks in advance, Garth

Did you model these hooks or download from a library?
The file contains a surface model and a mesh model. I’d get rid of the mesh model since it has a few flaws and the surface model is easier to repair.
Some surfaces aren’t trimmed correctly. You can find open edges with the _ShowEdges command.
I assume you will print all 5 parts separately and then put a bolt / axle in?
I’d add some tolerance between the parts. A gap of at least 0.2 mm to make sure the hooks don’t rub against each other.
To export the parts, select one after another and click File, Export selected. Xou may also right cclick the save icon.
