You need to call drawline() from an On Draw trigger.

Attached is your model, modified to draw a line from Queue1 to Queue2 from within Queue1's On Draw trigger.

Here's a start (references a pointer label to 'otherObject'):

drawtomodelscale(current);
int numsides=4;
double diam=0.2;
Object otherObject=current.otherObject;
Vec3 fromLoc=current.getLocation(0,0,0).project(current.up,current);
Vec3 toLoc=otherObject.getLocation(0,0,0).project(otherObject.up,current);
double theta=Math.degrees(Math.atan2(toLoc.y-fromLoc.y,toLoc.x-fromLoc.x));
fglRotate(theta,0,1,0);
Vec3 between=toLoc-fromLoc;
double theta2=Math.degrees(Math.asin(toLoc.z/between.magnitude));
drawcolumn(fromLoc.x,fromLoc.y,fromLoc.z,numsides,diam,diam,between.magnitude,0,90-theta2,0,255,255,100);
 
return 0;

I added a shape to your model whose onDraw trigger draws the line. It isn't currently possible to draw a line once and have that become an object in its own right that automatically drawn. The line needs to be drawn for every frame - hence the use of the onDraw trigger that fire's every time the screen is drawn.
