How to make a drawing from a part NX

Using the NX Drafting tool, you may generate a 2D sketch from a 3D model. In this simple example, we will utilize the 3D model shown in Figure 1.

First, we must launch the Drafting application. Navigate to File > Drafting while the 3D model is open in NX. This turns off the Modelling programme and launches the Drafting application.

When you run the Drafting application, the Sheet dialogue window (figure 3) will display. Here, you may select from pre-defined templates for the document or build a new one.

The Populate Title Block dialogue window (figure 4) will display once you pick the sheet. Here, in the lower-right corner of the page, you may define some sketching primary identifying fields.

Figure 3 shows the Sheet Dialogue window.

The 2D drawing can be added after the paper has been properly specified. The View Creation Wizard button (figure 5) can be used to add a desired view to the drawing paper.

Figure 5 shows how to add the desired view.

The tab Portion (figure 6) allows you to pick the part for which you want a 2D depiction. In this instance, the full assembly will be chosen.

The draw scale ratio, as well as various variables for lines and preview style, may be selected via the Options tab (figure 7).

Over the Orientation tab (figure 8), you may choose the view you want to create, including three-dimensional views like Isometric.

Over the Layout tab (figure 9), you can choose the placement technique and whether or not to add any extra views to the drawing.

Figure 9 shows the Layout tab.

Figure 10 depicts the outcome of the view development process.

Section views can also be added to further detail the model. This is accomplished by using the Section View button, as illustrated in Figure 11.

Figure 11 shows the Section View tool.

The placed view should be selected once the Section View dialogue windows appear. As a result, a hinge line (shown in orange in figure 12) defining the cross section to be projected should be set at the required location above the placed view. The black arrows at the ends of the hinge line require special attention. They indicate the direction in which you should be gazing at the projected segment. The direction can be switched if required by utilizing the Hinge Line option in the Section View dialogue windows.

After selecting the segment, position it over the paper sheet as illustrated in figure 13. Repeat this method until all of the model's essential portions are represented.

The fundamentals of sketching in NX

1. Make sure the part file is the active component in NX.
2. To launch the drawing application, select Drafting.
3. Choose NTNU as the drawing template.
4. Fill out the title block information. It is also possible to postpone and update later.
5. Make a basic view.
6. Create projected views, detail views, and section views.
7. Dimensions should be included.
8. Check the drawing and update the title block information.
9. Save the drawing as a PDF.

Modeling is divided into two ways. One is to set your geometry to 0,0,0 for all components that will be placed in parent assemblies. The alternative is to be in X-coordinate space, where X is the controlling coordinate of the parent. For example, consider aircraft or vehicle coordinate space. Let's start with where you should begin your portion!

• The first or major feature should be associated with the Datum Coordinate system at 0,0,0.

This is often true for any item that may be utilized in many locations or assemblies, independent of the coordinate space in which you are working.

• If you're working on a one-of-a-kind part in coordinate space, the major feature will almost certainly be a Datum Coordinate system at a different location and orientation dependent on its placement in the parent assembly. This is common among aeroplane makers, as well as automobile, shipbuilding, and other major constructions. Because the part is constructed "in-position," you don't have to deal with top-level assembly limitations.
• NX is a history-based modelling tool that values the sequence of creation. In general, the overall form should be defined before adding particular features such as threaded and counter-bored holes, blends (fillets & rounds), chamfers, and so on.
