Week 2 Challenge : Surface meshing on a Pressure valve

here given out of 3 target length the 5 mm is been applied on the body,for the column 3 mm is applied we could have did it with the 5 mm also but 3 mm is giving a accurate mesh type for the following and a refined version of the model and at last the valve and spring is been applied as 1 mm for the better mesh quality in the model so as to cover the edge to edge quality for analysis

herefore,the 1 mm is best for the better mesh quality as there is no missing edges in the cornes while meshing.
