The idea is to speed the roughing out of shapes using primitives without always having to move them from the world center. Ideally the gizmo will have a button to mirror the mesh geometry but not change the center point location of the mesh. Ideally the mesh will be a new Scene object with the gizmo on by default so it can be moved and scaled into position. When the brush touches a mesh the new mesh is inserted with its center point aligned with the mesh surface. Once a mesh is chosen the user would either chose drag radius or just insert which would insert the mesh at its default size. Dead Panic Studios (Civilization:Beyond Earth, Orcs Must Die, BattleBorn) wants to reward our fans with free stuffIncludes:2 insert multi mesh brushesJoin. Ideally in Nomad it would be a brush with a library of meshes in the stroke menu the same way we choose an alpha. I believe in ZBrush it is called the Insert Mesh Brush. You are also not just limited to application primitives but custom meshes you have created like greebles, spikes, engines, etc. I have seen in ZBrush and 3DCoat and some VR sculpting applications the ability to add a mesh not just at the world center 0,0,0, but also where a brush hits a mesh surface.
