I think my axis settings should be correct, that's why the animator can be run, now I open the huddled robot here and find that the model has completely disappeared, I'm confused, if you can, allow me to you send the step file

Hello, thank you for your reply, can I show you my step file by some means, I imported this file through cad importer, the coordinate information of his axis should be very similar to the abb robot in the demo, so I dragged all the parts in my robotic arm to the AXIS in the abb robot. After the dragging was completed, the animator that was originally in the demo and mounted on the abb robot ran very normally after running. But after I import robot ik and robot path and run it again, the robot shrinks into a ball. I tried to build it several times, and finally this happens. I am very distressed, it wastes a lot of my time, the picture below is The situation of my axis, if possible I would like to send you my robot step file, then you can try it。
