Grasshopper – Thema – railings – Creating railings along any kind of curves).
Railings shall respect those proportions.
Step 1 : Lines and intervals
Let’s transform lines into pipes.
Problem, the interval between bars is not 11cm anymore. Let’s fix it.
The length we’ve got to consider is (Space-Between)+(2xRadius).
Let’s check with cotations
This solution should work along a curved line.
What if we have a rectangular section?
Let’s create a rail with a rectangular section.
The Calculation of the Length now uses the rectangle’s dimensions
We complete the system
For a straight line it works
For a curved line it does not work. The orientation remains the same.
We will correct this with the Orient component and the creation of a set of Horizontal Frames. Connect the Curve to Horizontal Frame and Parameter to Parameter
Now connect Frame to Plane. It creates a bar with the correct orientation
Now it works with any type of curve
Definition for Dimensions
And for tubes, tubes are enclosed in a box that make things easier.
