Hypermesh External API

Altair Forum User

How to open external instance of HM using Visual Studio? I'm trying examples provided in the documentation of HM Ext API but not getting success ? Can somebody help me in writing a sample program to start the session, import the model and end the session. ?

 

Thanks!!!

What do you mean 'not getting success'?

 

You should find out the cause first instead of searching a new one.

 

I did that example and it works!

Check your VS version, it must be compatible with the one built HM

Can you please share the demo code which worked for you and the process to link the library files?

I'm getting  the following Error:  'module machine type 'x86' conflicts with target machine type 'x64' ' . I tried to get Visual studio 64-bit, but didn't get, so how you did? Whether you had tried with 32-bit hypermesh?

Demo code is in hm folder

Everything targets to x64.

I did in the same way you suggested, but now there's another issue, debugging is taking a lot of time.

That means you did something wrong.

I'll share the below code:

 

#include <stdio.h>
#include <stdlib.h>

#include 'hm_extapi.h'
#include 'hm_extapi_error.h'

HM_ExtAPI*  xAPI = NULL;

void open_api();
void close_api();

int main()
{
    open_api();

    bool model = false;
    model = xAPI->ImportModel(HM_ExtAPI::AUTO, 'D:\veer\HM Files\HSG.stp', true);
    printf('model value is %B\n',model);
    close_api();
    scanf('Enter something to continue');
    return 0;
}

void open_api()
{
    int err_code;

    printf('Opening API...\n');

    xAPI = Open_HM_ExtAPI(&err_code);

    if (err_code != ERR_XAPI_SUCCESS)
    {

        printf('Error \n');

    }

    printf('API ready.\n');
}

void close_api()
{
    if (xAPI)
    {
        printf('Closing API...\n');
        Close_HM_ExtAPI(xAPI, true);
        printf('API closed.\n');
    }
}

 

 

I have linked the required library and header files, and trying to run simple code to import the model, 

Can you please briefly share the whole process?

Thanks!!!

Hey Tinh,

I was able to create session of hypermesh. Can I get the Id's of components , surfaces only using external api functions?

Thanks!!

tinh

Yes, you can do it. I don't remember the functions, search it in samples
