Pro/ToolKit reading assembly data

Pro/ToolKit reading assembly data

Could you please help me with the following problem.

I get geomtry (thesselation) of the part using the following code:

ProError Convert_Part(ProMdl Mdl, ProMatrix Matr)

{

  ProError status = PRO_TK_NO_ERROR;

  ProName WName;

  ProCharName Name;

  ProSurfaceTessellationData data;

  ProSurfaceTessellationData *Output;

  ProVector Vect, CoM;

  ProMassProperty mass;

  Pro_surf_props prop;

  ProMatrix PrevMatrix, IM, _IM;

  int n_obj, i, j, k, clr;

  char *lVerts = (char *)calloc(100000000, sizeof(char));

  char *lFacets = (char *)calloc(100000000, sizeof(char));

  char tmpVert[100];

  char tmpFacet[100];

  int offset = 1;

  status = ProMdlNameGet(Mdl, WName);

  for (i = 0; i < 4; i++)

  for (j = 0; j < 4; j++)

  PrevMatrix[i][j] = AsmMatrix[i][j];

  status = ProSolidMassPropertyGet((ProSolid)Mdl, NULL, &mass);

  fprintf(UcfFile, "  material = %s;\n", GetPartColor().c_str());

  Output = (ProSurfaceTessellationData *)calloc(10, sizeof(ProSurfaceTessellationData));

  status = ProPartTessellate((ProPart)Mdl, 0.01, 0.1, PRO_B_TRUE, &Output);

  status = ProArraySizeGet(Output, &n_obj);

  for (i = 0; i < n_obj; i++)

  {

       data = (Output[i]);

       for (j = 0; j < data.n_vertices; j++)

       {

            sprintf(tmpVert, "  %lf, %lf, %lf;\n", data.vertices[j][0], data.vertices[j][1], data.vertices[j][2]);

            strcat(lVerts, tmpVert);

       }

      

     for (j = 0; j < data.n_facets; j++)

     {

            sprintf(tmpFacet, "  %d, %d, %d;\n", data.facets[j][0] + offset, data.facets[j][1] + offset, data.facets[j][2] + offset);

            strcat(lFacets, tmpFacet);

     }

     offset += data.n_vertices;

  }

  fprintf(UcfFile, "Vertices = {\n%0s  };\n", lVerts);

  fprintf(UcfFile, "Faces = {\n%0s  };\n", lFacets);

  free(lVerts);

  free(lFacets);

  status = ProPartTessellationFree(&Output);

  return status;

}


I works correct. My next step is to get the same data for all parts in

the assembly. For that I use the following code:

ProError Convert_Assembly(ProMdl Mdl, ProMatrix Matr)

{

  ProError status;

  ProMatrix Prev;

  int i, j;

  status = ProSolidFeatVisit((ProSolid)Mdl, VisitFeat, NULL, NULL);

}

ProError VisitFeat(ProFeature *feat, ProError status, /**ProMatrix/*/ProAppData/**/ AppData)

{

  ProFeattype FeatType = 0;

  ProAsmcomp *AsmComp;

  ProMdl Mdl;

  ProMdlType MdlType;

  ProMatrix Matr;

  ProMatrix PrevM;

  ProMatrix EndM;

  int i, j, k;

  for (i = 0; i < 4; i++)

  for (j = 0; j < 4; j++)

       PrevM[i][j] = AsmMatrix[i][j];

  status = ProFeatureTypeGet(feat, &FeatType);

  if (FeatType == PRO_FEAT_COMPONENT)

  {

       AsmComp = feat;

       status = ProAsmcompMdlGet(AsmComp, &Mdl);

       status = ProMdlTypeGet(Mdl, &MdlType);

       status = ProAsmcompPositionGet(AsmComp, Matr);

       for (i = 0; i < 4; i++)

       {

            for (j = 0; j < 4; j++)

            {

                 EndM[i][j] = 0;

                 for (k = 0; k < 4; k++)

                      EndM[i][j] += Matr[i][k] * PrevM[k][j];

            }

       }

       if (MdlType == PRO_MDL_PART)

       {

            Convert_Part(Mdl, EndM);

       }

      else

       if (MdlType == PRO_MDL_ASSEMBLY)

       {

            Convert_Assembly(Mdl, EndM);

       }

  }

  return PRO_TK_NO_ERROR;

}

When I try to process the assembly from the samples [PROE_PATH\vbapi\vbapi_examples\models\drill_chuck.asm] the

program give me data for two parts of three and Pro/E / Creo closes.

It closes without any errors or warnings. It simply silently closes.

At the same time if works correct again when I create new assembly and

add there same parts from mentioned sample model if I add parts to

assembly from the assembly's folder.

Could you please give me a hint what might lead to such abnormal

program behaviour? Any suggestions and comments would be highly

appreciated.

Hi all,

Vladimir,

You should question the validity of this statement:

for (i = 0; i < n_obj; i++)

{

       data = (Output[i]);

       for (j = 0; j < data.n_vertices; j++)

...

HIH.
