Si elegimos Caras, las seleccionamos y OK. Fundamentalmente es utilizada para cuerpos laminares. Si deseamos extraer una cara tendremos que seleccionar el icono Cara: Nota: Cuando extraemos Caras podemos hacer que los huecos o agujeros de una superficie sean borrados.
Tambien podemos seleccionar las caras de un objeto que tengan un nombre concreto. Los tipos de Superficies resultantes, son maneras diferentes de calcular el cuerpo laminar. Con esta orden crearemos puntos en diferentes cuerpo como curvas, splines, caras,…creados con anterioridad. El porcentaje inicial y final es para acotar en tanto por ciento desde donde a donde va a colocar los puntos. Tolerancia cordal. Estos nodos son los puntos que ligan los segmentos de la spline. Si deseamos no seguir haciendo curvas seleccionaremos Romper cadena o hacer clic en MB2.
Permite un mejor control de la curva para evitar ondulaciones indeseadas. Primero elegimos el tipo. Lo que conseguimos con esto es una curva que une otras dos como si de un puente se tratase.
Le podemos indicar la asociatividad entre nuestro cuerpo original y la que obtenemos. Si una vez envuelta la queremos desenvolver seleccionaremos No envolvente. Los segmentos los podemos dividir de diferentes maneras. Conseguiremos dividir una spline por sus nudos. Siempre se trabaja en el croquis activo. Lo que nos crea son curvas de Sketch de color ciano, las curvas normales de modeling son verdes por defecto.
Para editar el valor de la cota, tenemos dos maneras: Se seleccionan las restricciones a borrar y seguidamente Remove Highlighted Contraints. Para renombrar un croquis modificamos su nombre dentro de la ventana de la barra de tares de Croquis.
Para borrar un croquis: Editar — Borrar, en el Navegador de operaciones del Modelo. No es necesario que el croquis este asociado a la cara para posicionarlo sobre esta. De todas formas, de la misma manera que no es imprescindible restringir tampoco lo es posicionar. Hay dos maneras de arrastrar una cota. Seleccionar el icono de acotar. En esta ventana podremos modificar el valor con una barra desplazable.
Existen ciertas variables que afectan a las acciones e informaciones del croquis. Elegimos el que deseamos borrar y OK. Si queremos mantener alguna de las vistas, primero hemos de moverlas a otro plano.
Con esta orden podemos copiar a otros planos o reposicionar vistas de una en una o varias al mismo tiempo. Estas vistas se han de crear con la vista expandida.

Opening NX NX 7. To start NX, use the NX 7. It may take a minute or so for NX to start the first time. Once opened, you will be presented with the window shown in Figure 1. Figure 1 - NX 7. NX part files use the extension. In this tutorial, a single part file will be used with one component. To create a new part, click the New button to open the New dialog Figure 2. For now, stay in the Model tab. Select Model from the Templates list the default and set the Folder to a location on your S: drive or desktop.
The default location may be stored locally on the lab computer you are using and might not be in your roaming profile it might not be accessible on a different computer. Once a folder has been selected, set the name of the part file. Click OK to start modeling. Like most modern PLM tools, the interface for NX contains numerous icons, lists, text prompts and other features that can be incredibly overwhelming. For now, we will focus on the sketching tools, part navigator, viewer and menu.
Figure 3 - NX 7. That means you build up a component from a set of features that are added in sequence. This sequence, and the details of each feature, can be edited later if the design needs to be changed. Features can be removed, inserted or modified to create almost any solid part imaginable.
This allows a precise and highly editable method for describing solid components and differs from the 3D free- form modeling approach freeform modeling is used in computer graphics applications such as making models for video games.
The features you add to a part will appear in the Part Navigator under Model History. For a new part, the only thing appearing in the model history should be a Datum Coordinate System. This is the 3D Cartesian coordinate system used in the part and includes an origin location and coordinate axes.
These are shown with the coordinate system indicator at the center of the Viewer. The general workflow for creating a part in NX is to create a sketch, extrude or revolve the sketch and then add features to the resulting solid part.
Sketches are 2D mostly drawings that are used to define a cross section of the part. This cross section can be extruded pushed into or pulled out of the plane of the sketch and rotated wrapped around a axis to form a 3D solid part. To create a Sketch. Click the Sketch button in the sketching toolbar Figure 4. This will open a new dialog Figure 5 for defining the sketch. The first step in defining the Sketch is to set the sketching plane. This is the 2D plane that the sketch will be drawn onto.
This plane can be derived from the existing Datum Coordinate System or can be based on geometry from an existing part you can sketch on the surface of a part. For now, start the sketch on the XY plane. To select the XY plane, move the cursor to the skewed lines connecting the x and y axis lines on the coordinate system indicator Figure 6.
You can select the YZ and XZ plane the same way. Click once to set the plane. The red asterisk next to Select Planar Face or Plane in the Sketch dialog will change to a green check indicating that you have completed a necessary step. For now, no other information is required. Simply click OK on the Sketch dialog to start the sketch. A blue sketch plane will appear on the selected plane Figure 7. Figure 7 - Sketch Plane You can now draw on the plane, but without re-orientating the view it might be hard to see what you are doing.
To align the view with the plane of the sketch, right-click in an empty space in the viewer and select Orient View to Sketch in the pop-up Figure 8. The view will rotate to match the plane of the sketch. For example, a box is made of four line segments with their endpoints constrained to connect to each other at the corners of the box and to be perpendicular to each other Figure 9. Figure 9 - A Sketch As you add elements to a sketch, NX attempts to fully constrain the sketch automatically.
A fully constrained sketch is completely defined by a set of parameters and object constraints. To see this process in action, draw the box shown in Figure 9. To do this, click the Line button in the sketching toolbar Figure Figure 10 - Line Tool The cursor will become a set of crosshairs with a small dialog attached. This dialog allows you to precisely define the location of the start and end point of the line based on the coordinate system of the sketch.
NX defaults to XY form for the x and y coordinates of the point. You can switch back to XY by selecting Coordinate Mode from the same dialog. This can be done two different ways. The first is to simply move the cursor close to the origin of the sketch coordinate system until the cursor dialog reads XC 0 and YC 0. Alternatively, you can type in the coordinates manually. First type in the x-value then hit the Tab key to enter the y-value.
Hit the Enter key to set the point. You can set the end point of the line in a similar manner Figure For now, set the point at 50,0. If case you are wondering about the dimensions used here, NX defaults to Metric mm for distance.
