Lesson 6 Creating Drawings

This lesson consists of creating a detail drawing of a bellcrank.

Objectives

After completing this lesson, you will be able to:

Set the background sheet color.

Apply centerlines.

Apply dimensions.

Create a section view. Create an auxiliary view. Define and use a sketched symbol. Create a projected isometric view.

Populate the title block.

Exercise: Create a Detail Drawing of the BellcrankIn this exercise, you do the following:

Set up the drawing. Create the base and top views.

Dimension the front view. Create the section view. Define a sketched symbol.

Create auxiliary views.

Complete the drawing.

Completed exercise

Set Up the Drawing

1. Open a new ANSI (mm) .idw drawing file.2. Click Format > Active Standard, and select the Sheet tab.3. Click the Sheet Color Swatch. Set the background color to White.4. Click the Sketch tab. Set the Snap Spacing to 100 mm.

Create the Base and Top Views

1. Click the Base View tool.2. Click the Open File button and navigate to Bellcrank.ipt.

3. Click the Change View Orientation button.

4. Orient the part to match the following view.

5. Click the Exit Custom View button.6. Click the sheet to place the view. Click the Projected View tool. Create a

top view.

Dimension the Front View

1. Activate the Drawing Annotation Panel.2. Use the Centerline tool to define centerlines between the holes.3. Turn off the visibility of the horizontal centerlines vertical extension lines

near the large hole.

4. Use the General Dimension tool to apply the dimensions to the front view.

5. Note that the precision has been lowered on several dimensions. Thissetting is available from the right-click shortcut menu.

6. Right-click the 12 mm dimension. Click Edit.7. Enter the abbreviation TYP. in the Text tab.

Note: TYP. implies that the 12 mm dimension is typical. It applies to allthree edges of the bellcrank relief.

8. Apply a hole note to the 10 mm hole. Edit it to indicate that it is a throughhole and occurs in two places.

9. Add and edit a hole note for the large counterbored pivot hole.

10. Dimension and edit the radii on the relief.

11. Dimension the perimeter radii. Since all three are the same, anabbreviation can be used.


7/13


Create the Section View

1. Activate the Drawing Views Panel.2. Click the Section View tool.

3. Click the front view to specify it as the base view.4. Click either side of the diagonal edge to start the creation of the section

line. Draw a line over the diagonal edge. A perpendicular constraintdisplays, indicating the section line is at 90 degrees to the diagonal edge.

5. Place the section view toward the lower right of the front view.6. Apply dimensions to indicate the depth and fillet radius of the relief.

Define a Sketched Symbol

Later in the lesson, you create two auxiliary views. In this sequence, you create aspecial symbol to indicate an auxiliary view.

1. Expand the Drawing Resources folder in the Model browser.2. Right-click Sketched Symbols. Click Define New Symbol.3. Zoom in on any area of the drawing and create the following sketch.

4. Click the Fill/Hatch tool.5. Click in the lower half of the sketch. Under Color Fill, select Enable.

6. Add a 10 mm line to the sketch.

7. Right-click anywhere in the drawing. Click Save Sketched Symbol.8. In the Sketched Symbol dialog box, for Name, enter Aux View Symbol.

Click Save.

The new symbol displays under Drawing Resources > Sketched Symbols.


9/13


You apply this symbol later in the exercise.

Create Auxiliary Views

In this sequence, you create auxiliary views to illustrate the slots milled in thebellcrank for the pushrod and damper connections.

1. Open the Drawing Views Panel.

2. Click the Auxiliary View tool.3. Click on the front view.4. Select the hidden line near the part edge.

The auxiliary view is created perpendicular to the line you selected.

5. Place the auxiliary view to the right of the front view.


10/13


Note: This auxiliary view contains more information than you really need.To keep the drawing concise, the view can be cropped.

6. Use the Crop tool to define the portion of the auxiliary view you want tokeep.

7. Dimension the slots width and radius.8. Right-click the auxiliary view. Click Edit View.9. Click Toggle Label Visibility. Set the View Identifier to C.


11/13


10. Right-click the auxiliary view. Click Alignment > Break.

Note: This step enables the view to be moved off axis in the drawing. Italso causes a large view identifier to be created in the base view. In thenext step, you remove that identifier.

11. Right-click again over the view. Click Edit View.12. In the Display Options tab, clear the Definition in the Base View option.

You still need a way to identify the View C in the front view. You do thiswith the sketched symbol created earlier.

13. Select the Symbols tool on the Drawing Annotation Panel.14. Highlight Aux View Symbol in the list. Clear the Static option. This enables

the symbol to be rotated after insertion.

15. Place the symbol near the dashed line used to create the auxiliary view.16. Click the symbol and drag near its blue dot to rotate it approximately

parallel to the hidden line.17. Use the Text tool to place the letter C adjacent to the symbol.


12/13


Note: The position of the symbol is not critical; however, it should berotated parallel with the line used to define the auxiliary view.

18. Use the same procedure to create View D, an auxiliary view of the other

slot.

Complete the Drawing

1. Click the Projected View tool.2. Select the front view as the base view.3. Click to create the isometric view in the upper right of the drawing sheet.4. Create a centerline and width dimension in the top view.

5. Right-click over Bellcrank.idw in the Model panel. Click Properties.6. Open the Summary tab.7. For Title, enter BELLCRANK.
