So I'm newer to houdini coming from 3ds max, and in modelling how can I simply duplicate an edge which is selected? In 3ds max I just had to select what I wanted and then hold shift and drag and that would make a copy, is their something like that in Houdini which I'm missing? seems like a must have, but i can't for the life of me find it, is it a keyboard shortcut like 3ds max or something else? I feel so dumb asking this but it's just not right in front of me like in 3ds max.

Thanks,

Daniel
