extern int UF_MODL_create_isocurve (
tag_t face_id,
int uv_flag,
double parameter,
double dist_tol,
tag_t ** isocurve_id,
int * isocurve_cnt );
| tag_t | face_id | Input | The face identifier. |
| int | uv_flag | Input | 1 = create curve along u isoparameter. 2 = create curve along v isoparameter. |
| double | parameter | Input | Parameter at which to create the curve. |
| double | dist_tol | Input | Tolerance value. The tolerance is only used when the input face is foreign or an offset of a non analytic face. |
| tag_t ** | isocurve_id | Output to be freed | Array of isoparametric curve identifiers. You may get multiple curves if the face is trimmed. The allocated arrays must be freed with UF_free(). |
| int * | isocurve_cnt | Output | Number of curves created.
