scaling shoulder model, display geometry vanishes, shifted body parts

[Jeremy Genter]

Hello Team,

I am having trouble to use the Scale tool. I am using a shoulder model and try to scale it to a patient.
I have an experimental marker set and computed virtuel marker for the glenohumeral joint centre and for the ellbow joint centre. For all these markers I generated model markers. However, when I use the scale tool some display geometries vanish, the spine is shifted way too much superiorly and the humerus is rotated almost 180. Can you give me some hint where the problem could lie? I have attached a picture to show the problem.

Hi Jeremy,

The issue has been reported and discussed earlier (link below)

A fix will be available in the next version. However if you'd like to continue working with version 3.3 you can use the suggestions on the thread above.

Please let us know how it goes,

Hi Ayman,

thanks alot for your help. It worked .

I am still curious (if you have time to answer), why were some of the geometry shifted and turned?


thanks,
Jeremy

Jeremy,

There are mesh files in the custom geometry folder used by this model that have the same name but different mesh/offset from those under the OpenSim distribution. If the program picks the wrong folder/files the mesh will show with wrong mesh/offset or orientation.

Hope this explains,

It does thanks.
