    Why isn't my part fully defined with tolerances using DimXpert

    Allan Bowers

      I have a turned model barrel which I want to send out for manufacture using paperless eDrawing and so concluded that DimXpert was ideal. As the part is predominantly round I was not sure how to pick ideal datums for the Auto dimension tool. Here is what I chose and the resulting dimensions which as seen only partially define (Yellow) the part. I am not sure if there is sufficient info for a machinist to complete the job.

      I have tried manually adding location and size dims but it keeps over defining the part and I can't get any of the Yellow parts to Green or fully defined.

       

      If the part had flat x, y and z surfaces on three features it would be easy to fully define. That is where I think it is having difficulties.

       

      I could do a drawing and publish it to PDF but that rather defeated the purpose of trying to use MBD as it is intended.

       

      As I am 12000 miles from where the part will be made, it makes sense to me to do it this way.
