I'm trying to import a CAD Modell exported via sim mechanics link out of Autodesk Inventor 2015 into Matlab 2014b.

No matter which kind of model I'm using I get different kind of errors and exceptions by using smimport(). I even tried to export and import the robot.iam used in the examples at http://de.mathworks.com/help/physmod/sm/ug/import-robot-arm-model.html

>> smimport('robot.xml')
Caught "std::exception" Exception message is:
bad lexical cast: source type value could not be interpreted as target

If I try to import the already in the setup included export files (sm_robot.xml) it works fine.

I compared the two xml files but did not see any markable differences (they are not identically since the original file seems to be generated via a solidworks export, but I can't see any problems in the file)

Any Ideas what I'm doing wrong??

"It seems that is a bug in SimMechanics Link caused by decimal issue ( "." vs. "," ). As an workaround, try to replace the commas with full stops (".") in the XML file." Thanks to @Emanuel Dogaru. I have fixed the problem with this easy Way.

If you change this Regional Settings, all xml-fils will run in the future.

It seems that is a bug in SimMechanics Link caused by decimal issue ( "." vs. "," ). As an workaround, try to replace the commas with full stops (".") in the XML file.

  Muchas gracias, increible la solución tan simple. Llevaba varias horas intentando arreglar ese error.

That is the solution... replace "," to "." its ridiculous a softWare that costs a lot of money doing this with us. I spent 4 ours of my day searching the solution, ridiculous.
