UF_CSYS_create_matrix第一个参数传递无效？？

sunmz_wjxy

base_face是为指定的一个面,下面的这个错误我怀疑是不是指定的这个面本身就有问题？？？？
这个问题很急，希望高手帮忙！！


error = UF_MODL_ask_face_uv_minmax( base_face,uvs );   // 得到指定面的U和V
/*printf("Error from Asking uv minmax = %i\n",error);*/

      {

//UF_get_fail_message ( error,message );
        sprintf( box_message,"Error Asking UV Parameters for Steel %s - steel skipped",object_name );
        uc1601( box_message,1 );
        goto donewithsteel;
      }


      params[0] = ( uvs[0] + uvs[1] ) / 2;                    /* Set params to find face midpoint */
      params[1] = ( uvs[2] + uvs[3] ) / 2;
