4) Tutorial A
is to experiment with surfaces aiming at showing a way of using Grasshopper on surfaces.
This is an example of what can be done with lofts, divide curves and intersections.
Everything is parametrically variable.
The model above is based on two curves drawn in Rhino and preferably, choose a surface from your project. Remember, this is only one of many ways to work and feel free to improvise.
At the end, screenshots of your models will be shown on this website.
_______________
In Rhino workspace, draw 2 (or more) curves on the Cplane. They don't have to be closed.
The same funtions are applicable to single open lines, polylines and splines.
In Grasshopper, double click and type "curve", pick the one below (from now on, components are written with "(...)" and are found by searching).
Right click on the curve component and choose "set one curve".
Then click on one of the curves, then repeat this with the other component.
In this example, "Crv" was renamed into "Top Crv" and "Bottom Crv" by right clicking.
What's the idea here?
Now, Grasshopper communicates with Rhino and changes made to the curves, in Rhino workspace, will effect the algorithm.
The idea is:
- to lift one curve
- make a surface (loft) between both curves
- make the top curve rotate, effecting the surface
- build planar surfaces as floors
