Create the Drawing Views 269 the drawing view you decide that the scale needs to be updated, you can change it in the Drawing View PropertyManager. Dimension Type Section The Dimension Type section is an often-overlooked section but can cause major issues with your drawing if the wrong option is selected. Basically, the two options determine how the value of the dimension is derived from the drawing view. In all orthogonal views, such as Top, Right, and Front, the Projected option must be selected since it specifies the dimension as it is projected onto the 2D drawing plane. The True option is used when trying to apply dimensions to nonorthogonal views such as Isometric, Dimetric, and Trimetric views. The True option is used in these views since a projected dimension will often be larger or smaller than the actual dimension for the selected features. You should never need to change these options since SolidWorks will automatically set the appropriate dimension type when the drawing view is created, but if you think the dimensions shown in the drawing do not match the value that should be displayed, make sure the appropri- ate option is selected. Cosmetic Thread Display Section The Cosmetic Thread Display section controls how the threads will be displayed in the drawing. Rarely do we change this option since this option is also controlled in the Detailing section of the Document Properties dialog box. But if you need to change the display option for cosmetic threads, you should know that the High Quality option can have an effect on your overall system performance depending on the threads that are being displayed. Now that you have seen the various options available in the Model View PropertyManager, it is time to create the drawing view by doing the following: 1. In the Orientation section, select the button for the Front view, and select the Preview option, as shown in Figure 7.2. 505434c07.indd 269 1/26/10 2:42:44 PM Chapter 7 • Creating a Simple Assembly Drawing 270 FIGURE 7.2 Specifying the Front view for the new drawing view 2. Ensure that the Auto-Start Projected View option is selected in the Options section. 3. In the Display Style section, ensure that the Hidden Lines Removed button is selected. 4. In the Scale section, ensure that the Use Sheet Scale option is not selected. 5. Move the mouse pointer into the graphics area, and the preview of the drawing view will move with the pointer. When the drawing view is approximately in the middle-left side of the drawing sheet, as shown in Figure 7.3, click and release the left mouse button. FIGURE 7.3 Placement of the washer subassembly drawing view 505434c07.indd 270 1/26/10 2:42:47 PM Create the Drawing Views 271 Now is a good time to save the drawing. If you look at the menu bar at the top of the SolidWorks interface, you will see that the drawing has taken on the same name of the part/assembly when the drawing view was created. Since there is no need to change the name, you will keep the same name in the Save As window, but you will still need to specify the folder location of the file before saving. Section the Washer Subassembly In the previous section, you added the Front view of the washer subassembly, and you can just leave the drawing with the one view and finish the rest of the drawing. But, as you can see from Figure 7.4, it may not be clear to the reader of the drawing where one part ends and the other begins. That is why, in drawings such as this one, we like to add a section view to clear up any confusion there may be as to how the parts are put together. FIGURE 7.4 Front view of the washer subassembly In Chapter 4, we already went through the process of creating a section view, so the following steps should be a quick review of the process: 1. Select Section View in the shortcut bar or on the View Layout tab in the CommandManager. 2. Move the mouse pointer to the middle of the top line of the washer subassembly until the midpoint is highlighted and the mouse pointer changes to include the midpoint relation, as shown in Figure 7.5. FIGURE 7.5 Highlighting the midpoint of a segment in drawing view O It can help to add a section view to eliminate confusion about how parts are put together in an assembly. 505434c07.indd 271 1/26/10 2:42:49 PM Chapter 7 • Creating a Simple Assembly Drawing 272 3. Slowly move the mouse pointer vertically, ensuring that the coinci- dent relation appears next to the mouse pointer while moving. When the mouse pointer is a short distance from the top of the washer sub- assembly, as shown in Figure 7.6, click and release the left mouse but- ton to specify the first end of the section line. FIGURE 7.6 Using the midpoint of a drawing view for section 4. Move the pointer to just below the bottom line of the washer subassembly at approximately the same distance in the previous step, as shown in Figure 7.7. Click and release the left mouse button to create the section line. FIGURE 7.7 Drawing a section line The Section View window, as shown in Figure 7.8, is something you did not encounter when you sectioned the lamp base in Chapter 5 since you sectioned only one part. Now that you are applying a section to more than one compo- nent, you are presented with a couple more options. The first thing that you may notice in the Section View window is the large blue box on the left side of the window. This window lists any parts that you do not want to be sectioned. Since you actually want to section both parts in the drawing view, you will not be adding anything. However, if you were to decide to exclude a compo- nent from the section, you would just select the component in either the graphics area or the FeatureManager design tree. 505434c07.indd 272 1/26/10 2:42:52 PM Create the Drawing Views 273 FIGURE 7.8 The Section View window To the right of the Excluded Components/Rib Features box are additional options that you can apply to the section. The first option, Don’t Cut All Instances, doesn’t become active until components are specified first. If a component is shown in the excluded component list and the Don’t Cut All Instances option is deselected, all the copies of the same component will be sectioned with the line created. If the option is selected, only the instances of the same component that are in the excluded list will be sectioned. The next option in the list, Auto Hatching, is used to specify how SolidWorks will apply section lines to components that are made of the same material and are next to each other in the section view. As you may know, each material type has a different hatch pattern to help identify the material. But since many users do not specify materials for their parts in SolidWorks, all the parts in the sec- tion will have the same hatch pattern. Selecting the Auto Hatching option will automatically adjust the hatch pattern by changing the angle and/or scale of the pattern to allow the reader to easily identify the components in the assembly. The Exclude Fasteners option, when enabled, will prevent standard compo- nents that were added to the assembly via the Toolbox from being sectioned. If the Exclude Fasteners option is selected, the Show Excluded Fasteners option will be available and will provide a preview of the fasteners that will not be sectioned. The last option, Flip Direction, will toggle the direction of the cutting plane when the section is made. This option is also available in the Section PropertyManager. To complete the section, do the following: 1. Select the Auto Hatching option, and click OK to close the Section View window. 2. Move the section to the right of the Front view, and click and release the left mouse button to place the view. The New section will be O The Section View window appears when you apply a section to more than one component. 505434c07.indd 273 1/26/10 2:42:53 PM Chapter 7 • Creating a Simple Assembly Drawing 274 labeled Section A-A, and the section line on the Front view will be drawn as well. 3. Since there are no other options that you need to worry about at this point, close the Section PropertyManager by clicking the green check mark. Figure 7.9 shows what the drawing views should look like. FIGURE 7.9 Drawing views created in assembly drawing 4. Before moving on to the next section, notice that the section view that was created does not have a centerline going through the center of the parts. This is a minor thing, but it always good practice to add centerlines to revolved parts in a drawing. Select Centerline in the Annotations flyout on the shortcut bar. 5. Select one of the lines that makes up the inner diameter of the washer, as shown in Figure 7.10. FIGURE 7.10 Selecting the first edge for adding centerline to drawing view 6. Select the second line of the inner diameter of the washer. The cen- terline will now be added to the view. Hit Esc or click the green check mark in the Section PropertyManager to exit the command. After the centerline was added to the view, you may notice that the centerline is a little shorter at the top of the section view, and it crosses over the section label at the bottom of the view. It is always good to take care of some simple housecleaning as the need arises rather than waiting until the end. So, at this time, you will need to 505434c07.indd 274 1/26/10 2:42:56 PM Create the Drawing Views 275 extend the centerline a little more beyond the top of the view and also move the section label down until the centerline is no longer running into it. 7. Zoom in close to the section view by spinning the scroll wheel down with the mouse pointer over the approximate center of the section view. Or if you prefer, you can click the Zoom To Area button in the Heads-up View toolbar and drag a window around the section view. 8. Move the mouse pointer directly on top of the section label, and click and hold the left mouse button. 9. While still holding the left mouse button, move the label to just below where the centerline ends, giving a short gap between the label and the centerline. 10. Move the mouse pointer to the centerline itself, and select it by click- ing and releasing the left mouse button. The centerline will be high- lighted, and drag handles will appear at both ends of the line. 11. Move the mouse pointer to the top drag handle, and click and hold the left mouse button. 12. Drag the end of the centerline until it extends approximately the same distance from the top of the section as from the bottom. Once the desired length is achieved, you can click anywhere on the draw- ing or hit Esc to deselect the centerline, after which the section view should look something like the one shown in Figure 7.11.

Although every com- pany has their own standards in what information in the BOM is displayed, they all have the same minimum information such as the item number, part number, description, and quantity of each component in the assembly. Additional entries such as Vendor Name, Material Type, Next Assemblies, and Used On can also be found on some BOMs. SolidWorks comes preinstalled with a set of BOM tables that will fill the needs of many organizations, but often it is necessary to update the templates to meet special needs. At this point, we will not be covering the process of how to create your own BOM template. This will be covered in detail later in the book, so for now you can download the BOM template that will be used in this chapter from the companion site. After downloading the BOM, save it in the same folder that you have been saving the rest of the templates to make it easier to find when the time comes. With the BOM template downloaded and added to the folder that contains the rest of your templates, it is time to add it to the assembly drawing you have been working on. To add a BOM to the assembly drawing, do the following: 1. Select the Tables flyout on the shortcut bar. 2. In the Tables flyout, click the Bill Of Materials button. 3. Before you can insert the BOM into the drawing, a message in the Bill Of Materials PropertyManager tells you that you must first select a view in the drawing that will be used to populate the list. You would at this point select any view that displays the components that you want to be shown in the table. Since you only have two views in this drawing, you can select either one of them.  You can nd the requirements for BOMs or part lists in ASME Y14.34-1996. 505434c07.indd 276 1/26/10 2:42:58 PM Add a Bill of Materials 277 Explore the Bill of Materials PropertyManager After selecting the view that will be used to populate the BOM, you will be pre- sented with many options for creating the BOM in the PropertyManager. It may seem like a lot of information to take in, but if you break it down into sections, it is easier to understand. Some of the sections shown in the PropertyManager at this time are available only when inserting a BOM, and the others will remain available when the BOM is already inserted. Table Template Section The Table Template section is available only when inserting a BOM. This sec- tion allows you to specify a standard or custom BOM table that will be inserted in the drawing. Since this section is available only when inserting a BOM, once you insert a BOM, you must delete it to change the template being used. Next to the name of the template selected for insertion is a button named Open Table Template For Bill Of Materials, which will launch the browse window to locate the desired template. Table Position Section The Table Position section contains the option to attach the inserted BOM to an anchor point on the drawing sheet. Each table type in SolidWorks, including the BOM, has its own anchor point in the drawing sheet that is used to attach the table to prevent it from being moved. The major advantage to using an anchor point for tables is that the position of the tables will be consistent in all drawings. BOM Type Section The options in the BOM Type section are used to determine which components will be shown in the BOM that is created. The first option, Top-level Only, is probably the most common. This option shows only the top-level parts and sub- assemblies of the current assembly. If the assembly being depicted in the draw- ing has subassemblies, then only the subassembly will be shown and not the components that make up the subassembly. If the Parts Only option is selected, all of the parts, including those in the subassemblies, will be shown, but the subassemblies themselves will not be listed in the BOM. Lastly, the Indented 505434c07.indd 277 1/26/10 2:42:58 PM Chapter 7 • Creating a Simple Assembly Drawing 278 option allows you to show an indented parts list that shows the top-level parts and subassemblies. Then the parts that make up the subassemblies will be shown in an indented manner on the BOM. Configurations Section Sometimes configurations are used in assemblies to create different versions of assemblies that contain different components and quantities to eliminate the need for multiple drawings. The Configurations section allows you to select the configurations that will be used to populate the BOM. The next section will then be used to specify how the different configurations are displayed in the BOM. Part Configuration Grouping Section If more than one configuration is selected in the Configurations section, the Part Configuration Grouping section is used to determine how the parts are grouped in the BOM. Each configuration will have its own QTY column in the BOM with the name of the configuration included. Since you will not be using this option in this book, we will not be spending any more time covering this option, but you may need to read up on these options in the SolidWorks help file if your organization plans to incorporate this approach to assembly drawings. Item Numbers Section In the Item Numbers section, you can specify how the numbering of the items in the BOM is handled. In most cases, you will not need to change these set- tings. The first option allows you to specify where the numbering starts, and in 505434c07.indd 278 1/26/10 2:43:00 PM [...]... approximately 1.25 inches long Click and release the left mouse button to create the first line Transition Between Lines and Arcs in Sketches When most SolidWorks users need to create arcs in sketches, the Arc tools are often their first thought But as with many things in SolidWorks, there is more than one way to create an arc in a sketch While still in the Line tool when sketching, you can quickly and easily... you make a change to the custom properties of the components, the fields are updated automatically In the past, you were not able to update the BOM without breaking the link to the part model, but in SolidWorks 2008 the BOM became bidirectional This means that as long as the link is maintained, the properties of the components will be updated when the cells of the BOM are updated Since you did not...
