SimMechanics Link with Inventor error

Hi
I'm trying to import inventor assembly to SimMechanics with smimport command. I keep getting this error: "Caught "std::exception" Exception message is: bad lexical cast: source type value could not be interpreted as target" I have tried different assemblies including robot.iam from SimMechanics Link. Inventor exports second generation .xml and .stl without errors. I'm using Inventor 2014, Matlab r2014a and SimMechanics link 4.4.
Edit: I succeed to import en example file from here: http://www.mathworks.se/products/simmechanics/download_smxmlschema.html so there is a problem with Inventor export? Also all my programs and windows are 64bit.
Also 1st generation export/import seems to work fine..
Edit2: Problem solved. I updated Inventor to 2015. I hope that this post will help someone in the future..

Hey, i have nearly the same problem. I can export successfully my CAD assembly from Inventor 2015 in second generation. but when i want to import it in matlab 2014b with the command: smimport('Hexapod.xml') i get this error: Caught "std::exception" Exception message is: bad lexical cast: source type value could not be interpreted as target.
Can someone help me??

Hi,
I have the same problem and didn't find any solution so far. I use Inventor Professional 2015 and I want to open my exported Second Generation model with Matlab 2015a. I get the same error message as written above:
Caught "std::exception" Exception message is: bad lexical cast: source type value could not be interpreted as target
First generation model import works fine, but second generation does not.
Did anyone find a solution?
Edit: It works now for me. It seems as if the problems were related to some subasseblies, which I used to build the main assembly. Especially subassemblies of imported parts (e.g. download parts), which I used more than one time in my assembly, made problems. I solved these problems by using dummy parts instead of these assemblies or by creating derived parts of these assemblies.

As noted in the comments above:
- Use the latest version of Inventor
- Check your subassemblies to see if they are unique instances or reused instances.

Hi,
if you replace the commas with full stops (".") in the XML file, you should fix the problem.
For more information, please have a look at the following MATLAB Answer:
