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.
