bad lexical cast: source type value could not be interpreted as target

Hello,

I am currently trying to simulate a robot dog that I have created on Autodesk Inventor. I would like to do a physical simulation on Simscape Multibody. I have downloaded the plug-in to convert the model, it works. However, when I import the model from Matlab to Simulink via the "smimport('file_name')" command, it does not work. Matlab indicates "bad lexical cast: source type value could not be interpreted as target". I have already changed the region parameters from "," to "." and it worked the first time for a test 3D model. Now that I want to import larger files (like the leg I've attached), Matlab shows this error message again. So I tried again with the region settings but it didn't work. Can anyone answer my problem?

I had the same problem. Open the .xml file with an editor and change all ',' with '.' Here is an example from my .xml file.

Change for example:

<Rotation>1 0 0 0 -2,2204460492503131e-16 -1,0000000000000002 0 1,0000000000000002 -2,2204460492503131e-16</Rotation>

to:

<Rotation>1 0 0 0 -2.2204460492503131e-16 -1.0000000000000002 0 1.0000000000000002 -2.2204460492503131e-16</Rotation>

If you use Ctrl+F in the editor and use the replace command you can debug your file within seconds.

Thanks! It worked for me!

Is there a solution to the issue? I'm also experiencing the same issue even though the formatting for the numerical value is correctly set.

Hi Thibault,

This is a bug caused by a decimal issue as a MathWorks staff mentioned here:

The workaround is to replace all "," with "." in the XML file.

Thank you
