Why doesn't addVisuals display the mesh on the robot ?

dhparams = [0 0 l1 0;

l2 -pi/2 0 0

l3 0 0 0;

l4 0 0 0];

%creat BodyTree

excavator=robotics.RigidBodyTree('DataFormat','row');

%base

cap = robotics.RigidBody('cap');

swing1=robotics.Joint('swing1','revolute');

setFixedTransform(swing1,dhparams(1,:),'dh');

cap.Joint=swing1;

%boom

boom = robotics.RigidBody('boom');

jnt2=robotics.Joint('jnt2','revolute');

setFixedTransform(jnt2,dhparams(2,:),'dh');

boom.Joint=jnt2;

%stick

stick = robotics.RigidBody('stick');

jnt3=robotics.Joint('jnt3','revolute');

setFixedTransform(jnt3,dhparams(3,:),'dh');

stick.Joint=jnt3;

%bucket

bucket = robotics.RigidBody('bucket');

jnt4=robotics.Joint('jnt4','revolute');

setFixedTransform(jnt4,dhparams(4,:),'dh');

bucket.Joint=jnt4;

%Specify Dynamics Properties to Rigid Body Tree

Hi,

Can you attach the complete code. The values of variables are missing.

Kindly make sure that the biggest dimension is smaller than unity.
