I have come back to Rhino to have another stab at surfacing vehicles. I gave up years ago because I was unable to accomplish this after at least 100hrs of youtube videos, trial and error and the manual (well written)
Perhaps I am expecting too much from a CAD tool, but these examples I see of vehicles are completely beyond my ability to grasp.
I suspect that the people that make these models have years of experience edealing with the issues I encountered trying to accomplish even simple surfacing tasks like:
Draw a horseshoe with the curve tool in x and y only. Connect the two ends with a second curve. Impossible to surface.
Draw a circle in x and y only. Impossible to surface.
Draw a complex curve in x and y only that, like a circle, encompasses an area. Impossible to surface.
(it can be extruded in the z plane) I
Now using the points of this complex curve, drag some in the z plane.
Impossible to extrude
No duplicate this curve and drag the duplicate in the z plane. Attempt to surface using 2 curves. Nope. join the two curves with one perpendicular straight curve. Nope. two straight cuves… now onw half can be surfaced, the other half just cannot be surfaced. Add a third stright line. Nope urgh.
Creata a curve network Make sure all the curves touch. Make surface. yes. yeay! but, surface curve and curves that surface were created from have different curvature ???
In face the further along the vehicle you get with the curves, the more mismatches between adjacent surfaces occur. Using the previous surface as one of the curves prduces odd effects and wrinkles.
This is just too hard
I do not mean to minimize the incredible work that must be required to manage objects in software that define all these elements and connect them, but CAD is just one tool of many required in my project and I cannot take 3yrs to master Rhino just to create a surfaced vehicle !
Any workflow tips that someone can give me wouldbe greatly appreciated.
I tried Tsplines but it was not able to represent the shape
I dont know how to use a mesh or even if it is a better method
I use curves because the splines that govern them are great for vehicles, but surfacing is a total nightmare.
