Hi, I want to renumber the Type mark of Light fixture or Fire Alarm Smoke detector in a particular sequence. I got the dynamo file from the web for the Car parking renumbering. So I try to modify it as per my requirement. In that file they are using the spline for the renumbering order. They are using the Bounding box points of Car Park and spline curve points to find the elements. In my case the bounding box of Detector doesn’t intersect the spline because by default spline lie on the floor. Herewith I have attached the snapshot. Is there any way to modify?
