How to Create a Drafting Sheet with Dimensions in Siemens NX 12

Two-dimensional CAD drafting sheets are essential for designers and engineers because they allow them to visualise their ideas. Engineers and designers use informational and detailed drafting sheets to improve products and parts so that they are fully functional before going into production. It will be explained in detail in the following steps how to create different views of the part and how to measure the part using the dimensioning tool. An organised, professional two-dimensional drawing sheet with dimensions in Siemens NX 12 will be demonstrated in this article, which is suitable for users of any skill level in CAD.

Part 1 Opening a Part File

1. Move the cursor to “Open” on the top left corner of the screen under the gray “Home” tab.

2. When you have located and selected the part file, press the “OK” button. A dialogue box with the label “Open” will appear. Following a click on the part file, a preview of the part will be displayed on the right.

A grey background with a white 3-D coordinate system will appear on the part after it has been opened in the part file.

Part 2 Loading the Part into Drafting

1. Select the gray tab labeled “Application” on the top left side of the screen.

2. Move the cursor to the left and click the “Drafting” icon.

The “Drafting” icon is a yellow caliper with black edges, and an “L” shape rests on top of the caliper.

Part 3 Creating the Size and Title Block

1. Select the most appropriate size for the drafting sheet to be used. On the left-hand side of the screen, under the blue tab labelled “Sheet,” look for and select the option “Use Template.” Make certain that “A – Size” is already selected before clicking “OK.”

In the United States, drawing sheets are available in sizes A, B, C, D, E, and F, each with its own specific dimensions in inches. This example shows the dimensions of a “A” sheet, which are 8.5 by 11 inches in size. Additionally, the “Standard Size” and “Custom Size” sizes for drafting sheets are both available. Please keep in mind that “Standard Size” is E size, which has the following dimensions: 34 by 44 inches.

2. Click on the “Drawn By” text box in the “Populate Title Block” dialogue box. Type your name and hit the “Enter” key. Click “Close”.

Part 4 Using the View Creation Wizard

1. On the left-hand side of the screen, directly below the grey “Home” tab, select “View Creation Wizard” from the drop-down menu. The “View Creation Wizard” dialogue box will appear after the dialogue box has been opened.

2. Select “Next” from the drop-down menu. Immediately to the right of the tabs, there is a green checkmark indicating that the “Select Part” option has been selected. The part has already been selected automatically and is highlighted in blue below the “File Name” field.

3. Select the dashed lines on the diagram. When you have finished making your third selection from the drop-down list under the checked box for “Process Hidden Lines,” press “Next.”

4. To make the part it will turn blue, select the parent (main) view as the “Front” view and then click “Next.”

The front view is the most common and popular main view in CAD drafting sheets because it is the most visible and accessible.

In the “Model Views” list, you have the option of selecting another view to serve as the parent view for the part.

5. Hover your mouse pointer over the yellow box with an L-shaped figure labelled “Parent View.” When you click on the “Top” view, which is directly above the “Parent View,” the “Top” view will turn yellow as well, as will the “Parent View.”

Check the drafting sheet to the right of the “View Creation Wizard” dialogue box; as you select different views of the part, the drafting sheet displays them. The “Top” view will appear above the “Parent View” in the hierarchy.

6. Select the “Isometric” view, which is located to the right of the “Top” view on the navigation bar. Uncheck the box next to the views in the grey box that says “Associative Alignment.” Click on the blue “Finish” button to complete the process.

On the drafting sheet to the right, the isometric view will appear to the right of the top view, and vice versa.

When viewing an object in isometric view, all of the angles are equal to each axis in the 3-D coordinate system, creating a three-dimensional representation of the object.

Part 5 Dimensioning the Part

1. The location of the views of the part on the drafting sheet can be changed by clicking the border surrounding the part and dragging it to a new location on the drawing.

An orange dashed line appears to aid in the alignment of the view with the others. Allow for some white space around the borders for measurements. It is not necessary to move the views; you can leave the configuration as it is.

2. Under the grey “Home” tab, select the “Rapid” tool from the drop-down menu. A dialogue box with the title “Rapid Dimension” will appear to the left of the screen.

The “Rapid” tool displays a lightning bolt with red arrows running across it, indicating the dimensions of the bolt.

3. In order to easily select lines for dimensioning, it is necessary to zoom in on the drawing sheet. To zoom in on a computer, use the wheel of the mouse to scroll down, or spread your fingers apart for a laptop.

4. Choose the first line from which you want to measure the length. This is the point at which your measurement begins. On the drafting sheet, you can choose it in any view other than the isometric view.

If the dimension is a radius, diameter, or the length of the line itself, an orange dimension will be displayed on the screen. If you want this dimension to appear on the drafting sheet, simply move the cursor to the location where you want the dimension to appear and click (it will turn black).

For a neat and organised drafting sheet, make sure that dimensions are placed outside of the borders of the views. Please keep in mind that the isometric view should not have any dimensions.

5. Choose a new first line from which to measure the dimensions.

The line that has been circled in the image above is the first line that has been selected for measurement.

A dialogue box may appear from time to time, requesting that you specify which line you want to use. Select the desired line from the list of available options.

6. Select the second line to which you want to add dimensions. This is the point at which your measurement comes to an end. When you’ve determined where you want to put the dimension, click.

The second line chosen to be dimensioned is the one with a circle around it in the image to the right.

7. Continue this process until there are dimensions on both the “Top” and “Front” views of the drawing.

In a drawing sheet, do not repeat the same dimensions twice because this is considered to be repeated information.

8. Move the placement of the dimension by clicking on it and dragging it to a new location on the drafting sheet in order to keep the drafting sheet organised. Unclick for the dimension to be moved to a new location.

When you hover over a dimension, it will turn red, and when you move it, it will turn orange.

9. If you make a mistake or decide that a dimension is no longer needed, you can delete it by right-clicking on it and selecting the “Delete” option from the drop-down menu.

10. To make the drawing sheet neat and presentable, reposition the dimensions so that there is some white space around the edges of the sheet at the corners.

Part 6 Saving the Drafting Sheet

1. Click the blue button “File” in the upper left corner, “Export”, and “PDF”.

2. Click the yellow folder with the green arrow under “Destination”. Choose where you want to save your PDF file and hit “OK”.
