So I think to get the edges of a dimension here means that you want to get the geometrical references of the dimensions.
- so for example when you select an dimension you can get via ProSelectionModelitemGet the model item and when it is a PRO_DIMENSION then you can use the API ProDimensionAttachmentsGet() to get the references. So it could be some code like this below:
/*==================================================================*\
FUNCTION : TestAnnotDimAttachmentWrite()
PURPOSE : Writes Dimensions Attachment to a file.
\*==================================================================*/
ProError TestAnnotDimAttachmentWrite (ProDimension* dimension)
{
char var [PRO_FILE_NAME_SIZE];
char line [500];
ProError status1;
ProAnnotationPlane ap_get;
ProDimAttachment *pro_array_dim_attachment_get;
ProDimSense *pro_array_dim_sense_get;
ProDimOrient orient_hint_get;
ProDimensiontype dim_type_get;
int i,j,k;
ProModelitem p_mdl_item;
int dim_sense_array_size,dim_sense_array_size_low,counter,counter_low,dim_attach_array_size;
int arr_size;
status = ProDimensionTypeGet (dimension,&dim_type_get);
MY_ERR_CHECK("ProDimensionTypeGet()", status, status != PRO_TK_NO_ERROR);
status = ProDimensionAttachmentsGet (dimension,
&ap_get,
&pro_array_dim_attachment_get,
&senses_arr,
&orient_hint_get);
MY_ERR_CHECK("ProDimensionAttachmentsGet()", status, status != PRO_TK_NO_ERROR);
if(status == PRO_TK_NO_ERROR)
{
/*------------------------------------------------------------------------
Info of ProDimAttachment : DIMENSION ATTACHMENTS .
-----------------------------------------------------------------------*/
if(pro_array_dim_attachment_get != NULL)
{
status = ProArraySizeGet ((ProArray*)pro_array_dim_attachment_get ,
&dim_attach_array_size);
MY_ERR_CHECK_SUCC("ProArraySizeGet()");
if(status == PRO_TK_NO_ERROR)
{
sprintf (line,
" + Dimension Attachments (%d found):",
dim_attach_array_size);
printf (line);
/* Traverse through 'dim_attach_array_size' number of 'ProDimAttachment' objects */
for(i = 0 ; i < dim_attach_array_size ; i++)
{
/* Each 'ProDimAttachment' contains 2 ProSelection Handles
Traversing through these handles and writing their info */
for(j = 0 ; j < 2 ; j++)
{
sprintf (line, " - Dimension attachment [%d][%d]",
i+1, j+1);
my_line_printf (line);
if(pro_array_dim_attachment_get[i][j] != NULL)
{
do_something_with_particular_attachment (pro_array_dim_attachment_get[i][j]);
}
else
{
my_line_printf(" > NULL \n");
}
}
}
}/* if(status == PRO_TK_NO_ERROR)*/
ProDimattachmentarrayFree (pro_array_dim_attachment_get);
} /* if(pro_array_dim_attachment_get != NULL) */
}/* if(status1 == PRO_TK_NO_ERROR) */
return PRO_TK_NO_ERROR;
}
- If you what to access the dimension elements - in this case we need to use the funciton ProDimensionLocationGet. Returns a structure containing the location of elements making up a solid model/drawing dimension or reference dimension. NOTE: In a solid model, dimension location values will always be extracted by this function with respect to the indicated model orientation. The locations and values will be different for the same dimension when that model has a different orientation and scaling factor applied. This does not apply for drawings.
- So here an example where I used ProDimensionLocationGet API
