Isoparam

Any isoparametric curve of a surface (in the U- or V-dimension) may be obtained by using this command. To do this, only one surface will be selected. Then, tip “u” or “v” to change the parametric dimension where the curve will be extracted and insert the parametric value of the desired coordinate (pick mouse functions make easier this operation).
