Question

NEW API for Mathcad Prime 3.1

Can someone point me to the user guide to use the NEW API in Mathcad prime 3.1

The help system mentions that the user guide is available but does not give a link to it, does not give an online help to it. Also, it seems to implt that you have to pay for teh API!!!!

If so this is ridiculous. 3.1 is advertised as having an API as part of its features!!!

Can someone shed some light on this?

Thanks

    Steve,

    The API is part of Mathcad Prime 3.1 install. Look for MathcadPrimeAutomation.tlb and MathcadPrimeAutomation.dll.

    Load the TLB into the Object Browser of MS Visual Studio (or Visual Studio Express ..free) and there are the API's, their

    methods, properties, enums and data types.

    What's for sale is the Mathcad Prime 3.1 SDK which is a package of documentation and source code examples

    including source to the Solidworks- Mathcad Prime integration.

    So to be clear .. API is free, SDK is for sale. BTW SDK is $9000 USD per company.

    Seriously? You are asking $9000 for the documentation for the API? That is what I would call a gross rip-off! In fact, I think it's the biggest rip-off I have ever heard of. You are basically asking $9k for a book!

      No, not $9000 per company for documentation.

      $9000 per company for the entire SDK, which is mostly source code

      examples.

      Once more, open the TLB in Visual Studio. There is everything. If you like, print to PDF.

      This is how to get started with C#

      Add a reference to the Ptc.MathcadPrime.Automation.dll

      add a using statement

      public partial class MainWindow : Window

      {

         ApplicationCreator app;

         public MainWindow()

        {

         var appCreate = new ApplicationCreatorClass();

        app = (ApplicationCreator)appCreate;

         }



         private void Button_Click(object sender, RoutedEventArgs e)

        {

         var ws = app.Open("PATH TO YOUR FILE");

         var inputs = ws.Inputs;

         ----------------------------- 

            Work with your file

           ---------------------------------

       

        app.Quit(SaveOption.spSaveChanges);

           }

      }

      I hope this is to some help.

        Interesting coincidence that I happened to be working on connecting to Mathcad Prime with VBA today.  After some playing around I have some working code.

        First some notes:

        - I am currently only interested in obtaining results from Mathcad (looking at outputs only, not inputs).  However, I assume similar code can be used to set values.

        - In the Mathcad document, you must assign your inputs/outputs under the "Input/Output" tab, in the "Integration" section.  Using the "Show as List" button, you can see the assigned Inputs/Outputs and view and/or modify their "Alias".

        - The following code will run through all the assigned Outputs and list their alias, real value, and unit (in the "Immediate" window):

        Sub MathcadPrimeGetValues()

          Dim MC As Ptc_MathcadPrime_Automation.Application

          Dim WS As Ptc_MathcadPrime_Automation.Worksheet

          Dim MCOuts As Ptc_MathcadPrime_Automation.Outputs

          Dim MCAlias As String

          Dim MCResult As Ptc_MathcadPrime_Automation.GetValueResult

          Dim FilePath As String

          Dim i As Long

         

          FilePath = "Mathcad File Path"

         

          Set MC = New Ptc_MathcadPrime_Automation.Application

          Set WS = MC.Open(FilePath)

          Set MCOuts = WS.Outputs

          For i = 0 To MCOuts.Count - 1

            MCAlias = MCOuts.GetAliasByIndex(i)

            Set MCResult = WS.OutputGetValue(MCAlias)

            Debug.Print MCAlias; MCResult.RealResult; MCResult.Units

          Next i

         

          WS.Close (SaveOption_spDiscardChanges)

          MC.Quit (SaveOption_spDiscardChanges)

          Set MCResult = Nothing

          Set MCOuts = Nothing

          Set WS = Nothing

          Set MC = Nothing

        End Sub

          In the following (and attached) Mathcad file, you can see that I've defined two variables and assigned their results as outputs.  By default, Mathcad gives the outputs the aliases "out", "out_0", and so on.  These can be changed manually to something more useful (if anyone knows how to do this programmatically, that would save me a lot of work - please share).  When I run the script above, I get the following:

          out    0.0762    m

          out_0    0.127    m

            So, I have made some headway but it is not possible to access the contents of an output value result that is a matrix composed only of strung values. It only works for numbers, great. Amy idea when this bug will be fixed?

            There are no bugs in Prime. Just missing features. A lot of missing features, but no bugs

              ‌and they want to change 9k for an sdk that doesn't even fully expose all of the objects in output values? What's the use of a matrix if you can only work with numbers?
