Toolkit Programming for relations

[Gary1705]

Hello,

I am trying to write a C++ code into Creotoolkit  to import relations from .txt format file and then regenerate the model. Can anybody guide me how can this be achieved?

TIA

Below is a chunk of code Ive done a few years ago.   I was adding a line to the end of the relations of parts.  Looking at the code here its not too difficult.   Creo treats relations as an array of text lines.  Its been a while since Ive worked with relations, but this worked for me in Creo 7. 

ProMdlToModelitem(mdl, &modelitem);

status = ProArrayAlloc(0, sizeof(ProWstring), 1, (ProArray*)&w_array);

status = ProModelitemToRelset(&modelitem, &relset);

if (status == PRO_TK_NO_ERROR)

{

status = ProRelsetRelationsGet(&relset, &w_array);

}

else

{

status = ProRelsetCreate(&modelitem, &relset);

}

w_ptr = w_line;    //  My text string

status = ProArrayObjectAdd((ProArray*)&w_array, PRO_VALUE_UNUSED, 1,

&w_ptr);

status = ProArraySizeGet((ProArray)w_array, &n_lines);

status = ProRelsetRelationsSet(&relset, w_array, n_lines);

if (status == PRO_TK_NO_ERROR)

//ProUtilMsgPrint((char*)"gen", (char*)"TEST %0s", (char*)"Relation added successfully");

status = ProArrayFree((ProArray*)&w_array);

sprintf(Message, "%s   %s", PartName, RelLine);

ProMessageDisplay(msgfile, "USER %0s", Message);

}

Depending on what you need you might be able to use ProInputFileRead with the PRO_RELATION_FILE option. The relations.txt file would be in the working directory, but you can give a full path or most of the toolkit API's support using $ENVIRONMENT_VARIABLE.

//Use append_relations = 1 to append the relations and != 1 (ex: append_relations = 0) to replace the existing relations.
int append_relations = 1;
status = ProInputFileRead(mdl, L"relations.txt", PRO_RELATION_FILE, NULL, NULL, &append_relations, NULL);
status = ProSolidRegenerate((ProSolid)mdl, PRO_REGEN_NO_FLAGS);

If that doesn't meet your needs (example: needing to edit the post regeneration relations), you can read the text file line by line using something like wifstream to read each line from the text file and put it into an array of text lines. Then you can use ProArrayObjectAdd and ProRelsetRelationsSet like the example code from @msteffke.
