Necessary preparations, assemble the first part and save it

The first lesson starts with necessary preparations.
After the start of NX your user interface can differ from the course screen. To make your screen show the same command set as the course screen, we will have to apply changes to the user interface once.

Correcting sketch, set and relax relations, trimming in the sketch

On the one hand, it does not always work as well as in a training video, i.e. one or the other end point in the sketch is not exactly on the target position, or in the desired orientation. On the other hand, during the development phase of a part, sketches have to be changed again and again. But position and alignment can be corrected with a few mouse clicks.

Arcs in the sketch, the extrude command and fine thread

The exercise has the following main points: The outer contour, like the long hole, consists of degrees and arcs that can be created with the Profile command … and yes, the part is not round, but flat!
For this purpose, the Extrude command is started for the first time, that has an astonishingly large number of possibilities, which will be used step by step in the exercises to follow. Finally, a fine thread is created as a location hole for a sensor.

Position sketch, combine bodies in extrude, mirror in sketch

Until now, all bodies were created in a single step. But this exercise requires the body to be created over multiple steps. That is, for the first time, the part is created by combining solids, which are added or subtracted. The Extrude command has appropriate options to add or subtract the generated profile. These options are called Boolean operations. And according to the symmetrical structure of the part, a new option is shown to position sketches. In addition, the part gets a symmetrical T-slot. In the sketch, only half is sketched, and then mirrored. And this groove should completely penetrate the body, even if the length of the base body is increased.

Exactly, but Datum planes are very variable and allow so many settings that a separate video is necessary. A simple cube placed on top serves as an exercise to illustrate the different options. One more thing: The creation of the new parts is no longer discussed. The videos start directly with the newly created part.

Trim body, mirror feature, working with the timestamp

The exercise part is divided into three construction stages: B1P-9-1, -2, and -3. As in production, the part is first roughly prefabricated and then, in the two following courses, further detailed step by step. After that, an additional course is available under B1P-9-A, as well as the first expert exercise under B1P-9-E. But first you will learn to cut a body using a plane, to mirror working steps, i.e. features and to work with the time stamp in part navigator.

Thread, sketch blocks, extrude with offset.

In this second building stage, you will create the thread, and thus get to know the extensive setting options of the command of the same name. With sketch blocks from the reuse library, you can quickly add frequently used contours to the sketch. And with the Offset option in the Extrude command, you save yourself the otherwise necessary generation of offset curves in the sketch.

Edge blend, create relations immediately, combining sketches and edges

In the third construction stage, only small things are actually missing. For example, the edge blend at the base of the socket. But the distance between the slot and the socket is smaller than the radius of the edge blend. In addition, the small wrench flat is created. The chosen method of working shows, on the one hand, how relations are created directly during the construction of lines and arcs, and on the other hand, that sketches and edges can be combined.

Fillet in sketch, reposition sketches, copy with copy paste

What is more constant than change? And such constant change makes the design of components a very dynamic process. Changing requirements always demand adjustments to the existing design. This usually includes the repositioning of sketches.
If these sketches are appropriately prepared for such a change, the adjustment is completed with just a few clicks. Work steps based on this are also moved to the target position. Prepared in this way, simple copying via copy paste is also quickly done.

Draft in extrude, ribs, methodology

In order to be able to remove castings and plastic parts from the molds more easily, draft angles are required on the vertical surfaces. Usually only one to two degrees of draft, and the parts relax easily from the molds. The versatile Extrude command also allows you to enter a draft. In this way, the vertical surfaces of ribs and outer contours can be given a draft. And the little geometric nasties that crop up in the course can be easily solved with the right methodology.

In the second part of the course, the feature is trimmed to the YZ plane, mirrored and the halves are joined. The remaining work, such as the creation of the tenons, the tapered hole, the edge blends are always done on the original half.

This additional course is once again about ribs, no, actually about the possibility of creating a ridge from a simple line, if necessary with a draft. Again, lines are trimmed, dimensioned and relations are created. And the mirror, on the bottom of the clamping plate, can also be created quickly with the Offset option in the Extrude command. As always in additional courses, nothing new, but practice makes perfect...

Extrude with internal sketches, naming features and objects

What works for holes must also work for the Extrude command: This refers to internal sketches with which the Hole command works. However, these can also be created and edited directly from the command in the case of the Revolve and Extrude commands. The part navigator no longer shows the internal sketches, but they can be made visible again at any time as an external sketch. And this brings us to the next keyword. In order not to lose the overview in complex parts, features and also objects can be named.

Pattern of features, circular and linear

Often areas of a construction repeat. In a terminal strip the mounting holes or in a turbine the blades. In most cases, these are simple rules that control the distribution of the copies, and this is how the patterns that gave this command its name are created. But complex rules can also be stored or tables or a completely individual distribution of the copies. This course starts with the complex topic of patterns of features, which will be deepened in the next courses.

Pattern of features by spreadsheet

If the distribution of copies of one or more features does not correspond to a simple pattern, the target positions can also be controlled by a spreadsheet. In addition, parameters of the features can be changed at the respective target positions. In the course, a custom hole is copied using a spreadsheet, positions are changed or deleted and the hole diameter is changed.

Welcome to the next "Test yourself"! In this additional course several previous courses are summarized once again. Here, the slot represents a typical problem for positioning features on curved surfaces. For the circular pattern, the count and span option is a real good choice. And as in practice, the part still has to be adapted to two customer requirements.

Pattern with points, pattern with references, composite and offset curves

This expert course deepens the knowledge of patterning features. On the one hand, the course shows how points from a sketch can be used to define positions for copies of features. On the other hand, external references can also cause the copy to change its shape at the respective target position. In addition, the part is to be designed variably. Length and width are changeable, according to the presented rule. Exactly here lies the core competence of associative constructions: They are not a snapshot, but they represent rules, rules according to which the geometries are defined.

Pattern methods in comparison, pattern with boundary, pattern face

How to create many copies quickly? This expert course deepens the knowledge of pattern. The central topic is the creation of a large number of copies using the example of a perforated plate. The previous courses showed the amount of information that can be passed to the copies. This is because no rigid objects are patterned, but rather features whose parameters or relations can be changed at the respective target positions. This allows each copy to be individualised, but also generates large amounts of data. For the creation of a large number of copies that do not need to be individually controlled, a different setting should therefore be chosen in the pattern command. In addition, the course shows how an array of copies can be defined via a boundary, for example a sketch.

Feature groups, positioning coordinate systems, general patterning

Complex constructions can contain several hundred features and should be structured. Using feature groups, such structures can be created and the construction becomes clear and comprehensible. Feature groups combine features as a group and can be patterned, changed, added to or coloured together. The patterning of the feature groups is done in this course via coordinate systems that allow individual orientation for each copy.

Sketching with reference curves (auxiliary geometries), create arcs in the sketch, position coordinate systems

Sometimes, auxiliary geometries are needed to create the required dimensioning or relation. NX calls such curves reference curves. After clicking on a normal sketch curve, it can be converted into a reference curve and vice versa. Dimensions can also be converted into reference dimensions in the same way and are then only used for information, not for controlling the sketch. In addition, the course shows the circular arc command in the sketch, which is used to create the grooves in the clamping disk. The position of the thread is positioned associatively, via measurements and references, centrally on the shell surface with the help of a coordinate system.

Welcome to the next “Test yourself”! With the knowledge from the last course, positioning the angular hole on the cylindrical surface is no problem in this additional course. This is because work steps can be aligned as desired using a coordinate system. And so that the position associatively adapts to the diameter, a measurement is generated again.

The aim of this video is to show the operating concept of this function using typical measurement tasks. In order to also be able to measure the weight of the body, the density is entered as a value in the first example and defined via the Material command in the second example. The control of the inputs is done via the info window.

Unite with regions, working with coordinate systems

Complex parts are created in several separate areas. The resulting solids are then combined using the external Subtract or Unite command. These external commands offer additional possibilities (work with regions) and are therefore recommended for more complex modeling. However, the order of selection is important for a stable model. It is also advisable to separate the position of an add-on element from the size and shape for more complex modelling. The position is defined via a CSYS and the size and shape as usual via sketches and subsequent commands such as extrude or revolve.

You only need two options for this edge rounding. Option “Stop short of corner” to only partially round the edges and option “Corner setback” to soften the corners. The task: the necessary edge blends are to be modelled at the tip of a deep drawing mandrel. To avoid unnecessary processing, only the tip is rounded. To avoid cracking at the case corners of the sheet metal part, softer edge blends are created.

Using the Variable Radius option, the value of the radius can be changed at defined positions. In the course, based on a practical example, the inlet radius in the corners of a drawing die is to be given a larger radius than the radius at the longest edges. The positions of the transitions are defined with points in this example.

How to generate expressions, comment expressions, group expressions

… and display expressions in the parts navigator and so on. In the previous courses, expressions have already been used sporadically, such as wall thickness or draft. They give the user the possibility to use expressions multiple times and thus to control the value centrally. But this is only the beginning. Such expressions, or parameters, could be in some relationship to other parameters, could form sums, could be calculated, in general terms. In this tutorial, we start by creating expressions (and their rules), annotating the expressions, and grouping them together. See also the next video.

In this expert course, you will learn to incorporate more and more design requirements from the specifications directly into the modeling. In this way, you free yourself from a constructive snapshot, to self-changing parts, according to the conditions. On the basis of the last exercise part, further possibilities of the expression editor are to be shown for this. Depending on the major diameter, the number of bolt holes should change. Depending on the thickness, the hole type should change. And in dependence of the thickness also the hole diameter is to change. In addition it is to be ensured that the inputs for the thickness lie between defined limit values, thus a check is generated.

With the help of commands from the Synchronous Modeling group, surfaces can be modified. It does not matter at all if the surfaces were created in NX or if they are surfaces from another CAD system. Even non-parametric surfaces of a neutral data format such as step data can be changed. Sounds tempting? It is! With parametric models, synchronous modeling can be used to adapt or modify existing surfaces. However, overwriting of existing parameters should be avoided.

Layers are numbered containers for objects. Each object is assigned to a layer. The different layers can be made visible or invisible. NX has 256 layers. The number cannot be changed. Each object can be moved on one of the 256 layers. So much for the facts. But what are layers for? What advantages do they offer in everyday modeling? Is working with layers absolutely necessary? This video answers that and also shows how easy it is to create a small macro and integrate it into the user interface.
