solidworks to simulink 3d

hello,

I converted solidworks assembly to VRML file and deleted spaces from .wrl file. Then i open the file with v-realm builder and added transforms as shown in the webinar. But when i open the file with simulink and try to rotate objects, each object rotate about the first axis so i couldnt obtain a relative motion. How can i rotate bodies relative to others?

note: i pasted objects under the children block in v-realm. Is there any other condition to have relative frames?
