Hello, CAD models as much as OpenSim models contain not just the geometry/meshes that you see visually, they also contain other info: Joint definitions, Constraints, possibly forces, controllers, .... As such there's no universal format to transfer arbitrary CAD models into OpenSim or into any other...

Hi Lee, Can you do the scaling without placing markers? At least this will help us identify the problem area. From there it's an IK problem utilizing some fixed/anatomical markers followed by moving the non-fixed markers. Note that to solve the IK problem the model needs to be able to move/adjust co...

Hello, My recollection is that this was an issue with visualization rather than scaling due to the fact that the model uses custom geometry/mesh files that the scaled model can't find. If you save the scaled model in the same folder as the original/pre-scale model and reopen it, it will display corr...

Hello, 1. Can you explain specifically what does not work and how? Generally when mixing or loading libraries/dlls from one system into another you need to know the specific compiler version/settings/runtime. Do you need to run OpenSim live in the loop or can you interact with it through command lin...

Hello, Can you step back a second and explain why you're trying to convert timeseries data (as represented by c3d file) into an XML file that contains fixed marker locations? What is your planned workflow? Typically the markers live on different segments/frames of the model while the c3d data is all...

Thanks for reporting, Lukas.

Much appreciated.

Hello, Motion files contain the time history of coordinates. If you want a motion file to represent bone fracture reduction then you should introduce a joint into the model between the two broken bones with corresponding coordinate(s) such that you produce the motion by changing coordinate values, p...

Hello,

Can you specify what platform are you on, and if this issue is model specific? If so, please provide the model or a pointer/link to it.

Thank you,

Hi, Please try the 4.5 Beta release on the downloads page and let us know how it goes, as it has this built into it. Likely since the bindings you copied from 4.4 are inconsistent with the rest of the build from source, the first dll attempt fails to load but other things could go wrong in the proce...

Hello, A motion file is just a text file on a tabular format (similar to csv but space separated) with a time column and corresponding coordinate values, an example can be found in the distribution, linked below from Tutorial 1: https://github.com/opensim-org/opensim-models/blob/master/Tutorials/Int...
