Two problems with .stl files

Post by Matteo Musso » Thu Dec 20, 2018 9:07 am

Hello everyone, I attached a body on the arm arm26 and I imported a .stl file created with Solidworks to specify the geometry.
The measurements of the body created in Solidwork have a diameter of 0.05 m and a length of 0.5 m, but when importing the file in Opensim I have to use a scale factor of 0.0005 to obtain reasonable dimensions; why? Isn't Arm26 in meter?
The second thing I don't understand is why I get the message 'Mesh Exo2.STL not connected to model..ignoring' in the Matlab Command Window, but in Opensim I see the geomtry of my body; I get this error only in Opensim 4.0 when I used the beta version I did not get it.

Thanks in advance for your answers!

It is possible that the geometry defined in solidworks is not centered, thus the scaling transformation is not applied correctly.

Hi,

Did you find a solution to the error message?
Mesh Exo2.STL not connected to model..ignoring
Cheers,
