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.

NURBs are the Non-Uniform Rational Basic Spline. NURBs 3d modeling is a term of 3d modeling, in NURBs 3d modeling curved faces and edge and vertex are formed using NURBs modeling tools and commands in Maya and other 3d computer graphics software applications. In this 3d modeling there is two way to start 3d modeling of any object. One is using the NURBs primitives i.e. starting with NURBs cube, NURBs sphere, NURBs cylinder etc. and other one method is NURBs 3d modeling using the CV (control vertex) curve tool and EP (Edit Point) curve tool. NURBs are Non Uniform Rational Basics Splines, and spline means a flexible curve that can be shaped without breaking it at any place. That curves are called NURBs curves or CV Curves. We have a CV curve tool in create menu of Maya. We always draw a NURBs or CV curve on some 2-dimensional surface such as a paper or canvas or sheet or something else like that. Editing NURBs curves means that we can have a lot of tools in Maya’s surfaces menu set that allows us to edit a curve before converting it into some 3 dimensional shapes which will be a surface definitely.

CV curves are frequently used for making a profile. It’s in most cases a profile curve. We create a profile curve for our model which have in our mind and then on our paper or perhaps on any type of 2 dimensional surface. We draw a profile curve with CV tool on our drawing and when we are satisfied with our profile curve we convert it into surface. This way we get a 3 Dimensional NURBS surface from Curves. Editing a curve means enhancing its shape before converting it into some 3 dimensional shapes. Maya give us a lot of tools for modifying and editing our curves.

This Video Tutorial will teach you the use of animation deformers for modeling purpose. Deformation of a 3d object is easily used for the modeling tasks if your creative sense is working at least.

The following text and image tutorial is very simple and the same which you can watch in above Movies.

Learn here in this NURBs 3D modeling tutorial series for the beginners about some specific concept of NURBs modeling. This site is providing you a valuable content and data about 3d modeling and animation. The modeling is performed in two ways, either with Polygon or NURBs. This definite tutorial is presented here just about NURBs tools and commands. As many of you know about NURBs modeling and it works with curved shapes. There are many types of modeling and these are created either with polygonal primitives or NURBs primitives. It is advantage of polygonal modeling that many of models are created with this way easily whereas the NURBs modeling are mostly used when you are going to create any curved shape object. The NURBs modeling is initially started with CV curve, afterward, the curve is modified according to desired shape by using extrude, bevel and revolve commands. So you have to visit our previous tutorial at first to learn about basics of NURBs modeling. There you will find complete guide of NURBs modeling. Once a curve is created, then you can create another one by generating duplicate using mirror command.

In the following tutorial of 3d modeling with NURBs, you are using extend tool to modify the shape of the curve along with required shape. Once you have done this work, then you can create the duplicate surface for right place. Sometimes the duplicate curve is created just for the thickness of the model. Watch this video about NURBs modeling and you will also find some other useful commands for 3d modeling of NURBs. The video link is given at the end and you can get access to it by just clicking on this link.

The free tutorial is explaining about how to model the ship in Maya. In this tutorial we shall especially teach you how to use modeling with NURBs in Maya. The modeling using here is belonging to mechanical modeling with NURBs in Maya and also capturing the process of base of ship. Modeling provides you such facility that you can perform real look of object in 3D modeling in Maya. There are several methods for modeling and all of them are used at specific time with certain condition. If you are going to create any kind of modeling about machinery then NURBs modeling is the best option for you to perform such job. It will apply upon the project from starting point to final stage. As you know that in NURBs we take start from CV curve and then apply bevel and extrude commands for the structure of real image. The starting curve is also called profile curve and it is frequently used by engineering projects. There are three parts of sea ship and here we are in very first part of it where we are just telling you about some important techniques in it. The next two parts will inform you about working stage with gradually. These two tutorials are also available on same site here, this tutorial is especially describing about boundary tools for mechanical modeling and with all three parts we shall go through from NURBs editing tools.

This tutorial allows you to learn how to use extrude command in NURBs modeling. The method to describe the tutorial is quite easy that you will perform it yourself after learning this concept here. In NURBs modeling, the extrude command is used to create 3D modeling with modern techniques. The Extrusion is used in Maya, 3d s max and AutoCAD at the same technique of modeling. The modeling is actually resulting of basic primitives of polygons and NURBs. These primitives are available in their relevant command or you can get access to them by choosing them from shelf menu bar. In NURBs modeling, the method is little bit different from polygonal modeling.IN NURBs modeling the object is first created with CV curve and then it is rounded by applying revolve commands. At this stage, it is completed but with rough look, therefore we can modify its shape more by applying bevel and extrude commands on its faces. When we are required to create NURBs modeling applying extrude command, then first of all we create CV curve there where we want modeling. The similarity in curve shape doesn’t matter. Now select the curve and apply extrude command, and you see that proper result is in front of you. So that’s all about description on extruding command in NURBs modeling whereas the video tutorial is linked in the bottom of tutorial. Click on this video link and watch the concept thoroughly.

This tutorial will show you about extrude command in Maya using CV curve in to make a NURBs surface. The extrusion is common command in Maya, 3d s max and AutoCAD for 2D and 3D software. The concept of extrusion is likely similar in both Maya and 3Ds max. The extrude command is applied in modeling either in polygon or NURBs. In polygonal modeling, we extrude the polygonal faces to give the model required shape. It change the look of your model completely, when you pick the polygonal primitives, they are in rough and simple shape. We can modify their shape by applying extrude and bevel command on it. In this part we are going to teach you about extrusion about curve, the curves are mostly used in NURBs modeling. In NURBs modeling, first of all the object structure is created with CV curve and then it is applied by extrude and bevel command. These commands are applied on face and edges respectively. If you want to create vehicle modeling, then NURBs modeling method will be proved very helpful in this matter. It will provide you good control vertices to control your vehicle modeling. This tutorial is just introduction of this concept of NURBs curve extrude in Maya.

In this tutorial of Maya modeling, we shall introduce you about NURBs primitives. The polygon and NURBs primitives are two main features of modeling which are both used at same rate of modeling. The 3d modeling doesn’t matter either with NURBs or polygon modeling. The method for their component level helps us to find detail. There are proper main menus of polygons and NURBs. The NURBs are actually olden name of surface, and now a day in latest version of Maya, there is surface menu with multiple commands. The component level tells us about detail of object. If you want to find component level of object then just right click on the object and choose editable poly. There are three component level of the object known as vertices, face and edge.
This method is for polygonal object in 3d modeling. At this stage, we shall know about vertices, edge and face of polygonal object. The vertices are assumed as just like boundary line of the object and edge is defined as connecting point. The vertices come into existence with the combination of edge and vertices. When we are required to construct the object, we make the shape of the object by the adjustment of their component level. There are also other primitives of the NURBS in create Menu these are CV (control vertex) curve tool, EP (edit point) curve tool and point curve tool using this tool you have to give two or three point for creating a curve between these points. The following video link shows you about basic concept of NURBs, so watch this video and learns more about NURBs primitives.

This tutorial will explain about how to use trim tool in Maya. This tool was first launched for working in Corel DRAW and later on it has been using in AutoCAD for several year. The trim tools are used for trimming of some part in the model. Later on, it was brought into Autodesk Maya where it is using in place of NURBS. The NURBS are actually similar name for surface and it is changed now in latest version as surface. The surface is now added into main menu set and when you choose surface as main menu, the rest of setting also changes along with main menu. The trim tools lie in Edit NURBS menu which helps us for trimming something. Usually we use trim tool for cutting the doors, windows, panes, sockets, exhaust holes, and much more. But it is just an idea. Trim tool gives you a very wide experience to do something different. You can model a multi storey building with trim tool by using it again and again on particular area and in this way you may get a much summarized shape for your multi story tower or building.

If we talk about video tutorial, here you can see that it is required to draw a curve. The curve is drawn with CV curve only in this condition if the object is in grid mode. So convert the object into grid mode using magnet tools. Go to create panel and choose CV curve and draw a line. If you look upon that curve, you will come to know that the curve has two manipulating handles which tell us that the curve is two dimensional. Go back to magnet tool and bring the model to back position. Now we trim the curve by using command from Edit NURBS menu. In this case you should first click the curve then with shift selected click on surface. We have created newly projected surface. Moreover video will guide you in case of any problem.

This tutorial is concerning with NURBS,which is computer graphical application for creating curves and surface for representing in free hand modeling with elasticity. NURBS are mathematical modeling application which helps one to study and analysis the surface of the object. Either it is its interior side or exterior. For example the designers use this application mostly because they care of every side and surface of the object. The NURBS are modified with respect to its components. There are much difference between NURBS and polygonal components. The channel box is used for changing values of components. The NURBS is in fact short form of Non-Uniform Rational Based Splines. NURBS were used in CAD and other construction purpose software because it is thought suitable for designing and mapping function. But later on it was brought in use in other graphics purposes. The connecting point of control polygon is called control point. Here you can also understand the concept of polygonal components. The sides of polygon are called edges, the connection of edges are called vertices whereas the centre of all vertices are called face. The same are defined in NURBS modeling. The experts want an easy and quick modeling within real time; therefore they use NURBS in their modeling. Even you can create human modeling using NURBS with accuracy. The major difference between poly model and NURBS model that polygon is drawn in straight line whereas the NURBS are curved in shape. The NURBS modeling is drawn with CV curve.
