Pose and orientation of my robot is incorrect in Gazebo and RViz

Pose and orientation of my robot is incorrect in Gazebo and RViz . I have exported the URDF from Solidworks using solidworks to URDF plugin. I didn't modify any option in dialogues opened during export. Then i created an URDF package in ROS workspace and spawned the robot model into the world which resulted in inverted pose of the robot as shown in picture.  my xacro file : https://www.dropbox.com/sh/d4wjdjie1s9nkja/AADpXvAZ2cvj3Kb44aI5bz9ua?dl=0
