Back to course overview « Lesson 5 Lesson 7 » NX7.5 NX7.5 – Drafting Tags: Drafting, detail view, font size, tolerances In this lesson, we’re going to have a closer look at drafting in NX. We’ll see how you can add an enhanced view of a detail, also known as Detailed View. In addition to this, we will se how we can change font sizes and how to add tolerances. It is recommended that you repeat lesson 11 in Modeling 1 if you need to refresh the basics of drafting in NX. For NTNU students: Download the drafting templates below: A4 template A3 template After this lesson, do the exercises below. Exercise 16-17 16 17 Make a machine drawing of the model below. Try to uncheck Smooth Lines for your final result. You can download the file if you desire, but try modeling it yourself. Make a machine drawing of the model below. This is the same model which you made in exercise 6. Use the template provided. ...

Back to course overview « Lesson 4 Lesson 6 » NX7.5 NX7.5 – Surface modeling Tags: Surface modeling, ruled, bounded plane, through curves mesh, offset surface, trimmed surface, face blend, thicken In lesson 5, we will introduce surface modeling. We are not going to go deep into the functionality of the tools, since we have a separate course for that. A surface in NX CAD is defined as a model without any mass. In other words: An infinitely thin surface. The following tools are introduced in this lesson: Ruled Bounded Plane Through Curves Through Curves Mesh Offset Surface Trimmed Surface Face Blend Thicken After this lesson, do the exercises below. The suggested solutions provided with these exercises may provide you additional tools that we don’t present in the lesson. Exercise 13 Model the shape below using surface modeling tools. Thickness for the surface walls are not necessary. Suggested Solution for exercise 13 Exercise 14 Model this racket using surface modeling tools. This is a tricky exercise, so we recommend looking at the suggested solution if you are stuck. Suggested Solution for exercise 14 Exercise 15 Model this surface model. You can add a thickness of 1mm using Thicken when you are done with the shape. Suggested Solution for exercise...

Back to course overview « Lesson 3 Lesson 5 » NX7.5 Lesson drawing NX7.5 – Assemblies Tags: Assembly, bottom-up, exploded view, component array In this lesson, we shall put together some parts that eventually will become the radial engine as in the picture above. For this assembly, we will use the bottom-up method, which is more common to use compared with the top-down. We are also going to introduce the constraint Angle. In addition to this, we will introduce Exploded view of an assembly. This is a way to separate the parts from each other, to see how the components are put together. Finally, we will take a look at Component Array, which allows you to add components in a linear or circular pattern. Click the link below to download the parts for this lesson, or try to draw them yourself by navigating using the tabs above (arrows on tablet/phone). After this lesson, do the exercises below. Downloads Radial Engine.zip Exercise 11 Model the parts and put them together into an assembly file. Remember to put all part files in the same folder. You can download the parts here if you don’t want to model them yourself. Suggested Solution for exercise 11 Exercise 12 Make an exploded view of the assembly as shown on the first picture below. You can download the parts here if you don’t want to model them yourself. Suggested Solution for exercise...

Back to course overview « Lesson 2 Lesson 4 » NX7.5 Lesson drawing NX7.5 – Assemblies Tags: Assembly, top-down, constraints, concentric, touch align, distance, perpendicular, sub-assembly We shall, for this and the next lesson, go more in depth of assemblies. There is mainly two ways to handle an assembly, top-down and bottom-up. In this lesson, we will focus on top-down. There will also be an introduction to several assembly constraints: concentric, touch alighn, distance and perpendicular. There will also be an introduction to what a sub assembly is. You may try model the piston rod depicted above by clicking on the attached lesson drawing in the tab above (scroll if you are on tablet/phone). If you just want to assemble the model, download the parts below. After this lesson you can do the exercise below. Downloads Piston Rod.zip Exercise 10 Model and assemble the figure below using the top-down method. Suggested Solution for exercise...

Back to course overview « Lesson 1 Lesson 3 » NX7.5 Lesson drawing NX7.5 – Patterns Tags: Pattern, bisector datum plane, pipe connecting tips In this lesson, we’re going to introduce an important tool: Pattern Feature. It is perhaps unneccessary to explain that this is a tool that allows you to copy features or bodies in various geometrical patterns. For instance, we’re going to take a look at how you can copy bodies along a customized curve, like on a roller chain(the parts for the roller chain can be downloaded below). In addition, we’re going to take a look at bisector placed datum plane, and how this is utilized. You can make the model in the poster image above by following the drawings attached in the tab above. After this lesson you can do the exercises below. Downloads Rollerchain.zip Exercise 8-9 8 9 Model the figure below. Use Pattern feature (Instance feature in NX7.5) to place the holes. Note that because of the asymmetrical feature, it is not possible to use a bisector placed datum plane to mirror one of the discs in this exercise. Suggested Solution Model the figure below. Hint: Use Draft in the Extrude dialogue box for the angled hole in the center of the model. Suggested...
