    Error CAD converter failed

    Hey there!


    I am currently working with Thingworx Studio and I have come across the following problem:


    I wanted to upload a .stp file (STEP) which should be supported by thingworx Studio. But when I want to add it, it fails.

    I have already tried to add it with the Run CAD Optimizer Option ticked, but I got the sam error as well.

    The size of the 3D shouldnt be the problem as I have already tested it with a smaller one and that failed as well.


    Any suggestions?


    P.s.: If you want to see the log files, you will have to tell me where to get them because I have no clue where to find them. Thank you so much

    in advance

        The logs are accessible from the ThingWorx Studio application window. You will find 'View Logs' link on the bottom-right of the window.

            I tested also the issue with Thingworx - version:

            Created a simple file form Creo Parametric model and exported it to step

            And added to resources in Thingworx 'Studio. I selected the option optimize. So the results is that it created pvz models with high low and medium .


            So I believe may be you need to check the step file if it is ok and could be retrieved in any other tools - for example in PTC Creo Prametric. I used for the test Creo Parametric 4.0 M010

            Hej Theresa,


            are you able to share that step-file?

              Is it a new installation or things used to work before?

              Can you successfully upload a .pvz with "Run Optimizer" checkbox ticked, or seeing similar "CAD Optimization failed" error?


              I have seen similar issue on a PC with missing / broken Visual C++ Redistributable. Just got it from the link below and installed - the issue was gone in 5 min. Download Visual C++ Redistributable für Visual Studio 2015 from Official Microsoft Download Center
