Regarding the Motionview result display issue

① In Motionview, I used mechanical tools to generate two bearings and solved them in Python format. In Hyperview, I can see the two bearings, but the models of my other objects are not displayed. However, if I submit on the Motionview interface, I can see the models of my other objects. How can I solve this problem?
② I have some pre made Motionview files that need to be sent to others to open. I sent them in MDL format, but the other party only had some Joint files to open. How can I save them so that others can open them perfectly on other computers?
③ Does the extension of mechanical tools in Motionview seem to not support objects within Rigidgroup for the internal and external reference bodies of bearings? I used a bearing and selected an object from the Rigidgroup as the reference body, but the solution would give an error saying that the reference body is not a part. What is the reason for this?

Hi @Jin1 ,

For your first question. Can you confirm if you are running the model via live animation or offline mode?

I did a few tests and I could not replicate your first issue. In addition, which MotionView version (2024,2025.0,2025.1) and Machinery Tools (1 or 2) are you using? Maybe if you could generate a quick representative model that shows this behavior, that would be helpful.

For your third question. I have also observed the same behavior. I will make a ticket with the developers to fix this. I have a workaround for this. Ungroup the rigid groups and only group the components that won't be the inner and outer bodies of the bearings. Then attach the inner and outer bodies to their respected group by a fix joint.

Best,

Christopher Fadanelli

Hello @Jin1,

1) What do you mean by submitting in the MotionView Interface? Do you mean Live animation? Are the results there visualized properly? Could you maybe share your model?

2) MotionView models may contain entities that are referencing other files like CAD graphics, curves etc. To properly share a model you need to go to File→ Export→ Model and check the archive and zip options. Then share the zip file.

3) When selecting body entities for any body selection i.e. joint, spring, force etc. then a body should always be selected. Rigid Groups are used instead of fix joints making it easier for users to organize assemblies.

Hope this helps!

Best regards,
Orestes

① That's right, it refers to submitting tasks in Motionview where geometry can be displayed. However, when exporting a py file and submitting it in Motionview, only the bearing model created by the mechanical tool can be displayed. Unfortunately, the model cannot be uploaded;
② I have already solved the second one using a relative path
③ You may not understand what I mean. I have two rigid body groups now, and I used Motionview's mechanical tool to create bearings between them. However, when creating bearings, I need to select the inner and outer Body models to be installed. I found that as long as the inner and outer Bodies exist in either rigid body group, solving them will result in an error

The first question is: Here is the screenshot you took. I submitted it offline in Motionview and then viewed the results of H3D in Hyperview, but there were no other geometric shapes of mine. But if I don't submit offline in Motionview, I can see normal motion and other geometries are also normal.
The third question: Thank you, that's how I solved it now.

I just tried other models but couldn't reproduce this issue. I'm very sorry, but this problem has appeared in my large model
