RevitCat: Gare do Oriente – Revit Nested Repeaters

In previous posts I described how to use Revit adaptive components and repeaters to start creating a model of Santiago Calatrava’s roof structure of the Gare do Oriente in Lisbon:
Part 1 – The rig for one structural column
Part 2 – Placing roof panels onto the rig

This time we will look at creating the structural elements to put on the rig.

Here is a youtube tutorial on creating the structural elements as an adaptive component, and placing the adaptive components to become a ‘Repeater’

Steps

Here is a quick checklist of steps required:

• Start new adaptive family
• Place a point at the origin, plus two more points
• Make the points adaptive
• Join all three points with reference lines, ensuring that 3D snapping is ON

Add an arc between points 1 and 3;  the arc must be kept planar with the 3 points, so it needs to be hosted to a rig (or alternatively a plane – not shown here)

• Place a hosted point midway along the line between points 1 and 3
• Place a reference line from that hosted point to…
