Determining Trail Value for two wheeler

draucis

Hello, 

I want to measure and plot the value of Trail. By default, there's no expression in Hypergraph which plots trail for the front tire. Is there any way through which it can be made possible? One way I came across was to establish a massless body at the intersection of the steering axis and ground and from that point to the contact patch we can take the trail value, this could work but I don't know how to plot the trail in hypergraph from these custom points and body. 

Regards

An Update on the question asked above.

I was able to create the massless body on the coordinate I need it to be in. Still, I am not sure how to plot the trail value in hypergraph.
