This is introductory tutorial of Birail tool. Birail tool is used for creating NURBs surfaces and their editing. This tool is included in Maya in advanced version of Maya and other 3D software. Many new problems are increasing day by day in place of old ones. The people are getting skill to meet these problems. In Maya surface menu, there are many powerful tools for creating new surface with CV curves in Maya. These surfaces are used in Maya at larger scale. Birail Tool makes a surface by extensive edges by a series of profile curves along two path curves. The consequential surface can support durability with other surfaces. The Birail Tool has options for sweeping 1, 2, or 3 or more cross partial curves along the two path called rail curves. The important surface is interpolated through the profile curves. Options put the pressure the profile curves have on the middle profiles of the shaped surface. A value of 1.0 means the primary selected profile curve has a greater pressure than the second profile curve. A value of 0 has the differing effect. By default, both selected profiles have an identical pressure value of 0.5. This option is obtainable only for a surface shaped with the Birail 2 Tool. That’s it for now, for more detail about this concept watch this video tutorial right now.
