I could do with a beginners guide on importing meshes in Rhino, made from within photogrammetry programs such as Agisoft Photoscan, orienting them, even a command that might be used to place curves on the mesh and then surfaces between such, best fitting a mesh , to use as a start point to then tweak. The goal being to end up with an accurate curves and surfaces model representing the engineering item I have photographed and turned into mesh using such as Agisoft.
I have a lot of projects that will start with capturing an object in 3D, I cant afford a scanner (who can ?) so I am using Agisoft Photoscan, generate a mesh from the object, then need to create a rhino model by sectioning the mesh, drawing curves to match it, create surfaces from curves, in other words turn the mesh into a hand crafted rhino model. Even folk with scanners need to then create and model a surfaces model from the scan. How is it done ? I am capturing engineered shapes including organic shaped forms such as exhaust manifolds.
any videos on meshes and rhino as its totally new territory for me and I need to read up or view videos, (far preferred) on it.
