I have a precast beam family and have a lot of instances of this family in the project for a viaduct I am modelling.
I need to populate a table of XYZ coordinates relating to the start and end point of each beam.
The problem I am having is that the main insertion point for the beam is based on a reference line located in the middle of the section, whereas I am looking for a point at the start and end at the bottom of the beam in the centre if that makes sense. I thought about getting the XYZ coordinates of the this line and then subtracting the difference from the Z value but as the beams are not necessarily horizontal, that will not give the right point.
I am looking to possibly draw a reference line along the bottom of the beam and get the start point and end point of this line. Is that possible?
Any help would be very much appreciated.
