Hi,

I'm trying to edit the code from the arm26 OpenSim model. What I'm trying to do is to replace the humerus for one created by us. The problem presented is that the system recognizes the bone but it doesn´t display the new humerus, I've already tried to show it (right clic>display>show), review the code searching for the old bone and replace the name. I know that it is recognizing the new humerus because the system hasn't crashed yet, it shows the body name at the navigator panel and at the view panel it shows something at the joints of elbow and shoulder where the new humerus is placed.
I also scaled the new humerus for fiting the place left for it
I'll attach some pictures and may be you can tell me what is happening or may be who else can help me.

Thanks

Hi Alejandro,

Where did you place your new geometry file and what is its extension?

File formats (.vtp, .obj and .stl) are supported, and the files need to be located under either of:
- Same folder as model
- Geometry folder under folder containing model
- Geometry folder under installation directory (e.g. C:/OpenSim3.2/Geometry).
- You can modify the search paths using the GUI/Edit->Preferences/GometryPath
If the file is in the right place and has the right format but doesn't display it's possible that there's a problem with the contents of the file. I believe .vtp files has to have ASCII encoding, you can check that by opening the file in Paraview a third party free application and saving it in the correct format.

Hope this helps,

Hi Ayman,

Thanks for your help, but I still have problems displaying the new bone. I did what you told me: save the .stl file in the same folder as model, saving the .stl file as .vtp with ASCII encodinig and it isn't displayed yet. I also changed the .stl extension to .vtp as I started using the other file.

It's still showing the same shapes at the shoulder and elbow joints when I go through the navigator panel: body>file name (humeroLilianaEscalado)>right cilc>display>show.

I hope you can help me, any advice will help me.

Hi Alejandro,

Can you post the problem vtp file so we can troubleshoot? Apparently you can see other vtp files on your machine already.

Thanks,

Alejandro-

are you changing the geometry name in your model to match the new geometry file you created?

Hi,

Yes James, I did changed the geometry nam in the model.

I'm trying to attach the vtp file but for some reason the page crashes and reloads the information.
How else can I show the vtp file in the forum?

Thanks

Alejandro,

You can open a bug report and attach the file (Help -> Report Bug from the application GUI).

- Geometry folder under installation directory (e.g. C:/OpenSim3.2/Geometry).
