I have imported my fuselage work from a photogrammetry program into Rhino. The nature of the beast means lines are a little wriggly’ in places and I wish to best orient this fuselage using lines I know should be matching x y and z axes.
To do so, I need to place planar surfaces through pairs of lines , i.e same frame line on port and stbd for horizontal fit, or fuselage seam above and below fuselage for vertical fit etc .and have best fit occur to these wriggly curves.
Imagine a fuselage ‘stringer’, it heads fore and aft between the fuselage main frames, it has a slight manufacturers curve in aircraft plan view, but mine also has a slight wriggle along its length in aircraft side view !
What command should I use to fit a planar surface through these port and stbd stringer lines if they have designed planar curvature but also are a bit wriggly ?
I found rectangular plane through points tool, but I have wriggly lines. Maybe I have to spend time making points along my lines then select those ?
Once I have these indicators of vertical and horizontal created I then need to select these and do a best fit of this fuselage to vert and horizontal, best fit to x y and z axes in fact.
What is the best way of telling rhino to take all surfaces that should be parallel and in e.g. the yz plane and best fit the object to that orientation. then that done, to best fit the surfaces that should be in the xy plane to such without losing the first alignment ?
This done I then need to improve the lines and curves, I need to best fit a new curve to existing wriggly curve. For those with the planar surfaces there is a modelling aid there though projectToCplane wil also flatten anything.
What command to draw a new curve through a wriggly existing one ?
