3-D Solid Part Models and Multiview Documentation from Technical SketchesThe technical sketches in Figures 10.160 through 10.168 are designed to be used to construct fully constrained 3-D solid part models. Any available parametric solid mod-eling software may be used. Refer to Chapter 9 Three-Dimensional Modeling as needed for a review of con-struction or datum plane set up, profi les, and part bodies using standard extrusion, revolution, or lofting methods. Use appropriate geometric and dimensional constraints to fully constrain each part. Apply 3-D features, such as holes, fi llets, chamfers, ribs, and thin wall operations (as required) to create a logical, easy to edit history tree.

Use the fi nished part model to generate associated multiview drawings containing appropriate drawing views to fully describe the part (ie; front, top, right side, isomet-ric views). As an option, make parametric changes to key dimensions and features in the part model and use these revisions to the model to update the associated multiview drawing.

Problems designated FOR 3-D ASSEMBLY MODEL are designed to be used as parts within 3-D Assembly Models contained at the end of chapter prob-lems for Chapter 20 Working Drawings.

3-D Solid Part Models and Auxiliary View from Technical SketchesThe technical sketches in Figures 13.47 through 13.53 con-tain inclined and oblique surfaces and features that may re-quire auxiliary views, to show true sizes and shapes. Con-struct accurate, fully constrained 3-D solid part models for each. Any available parametric solid modeling software may be used. As required with your solid modeling soft-ware, determine the appropriate method to creating, rotat-ing, and positioning compound angle datum/construction planes needed to correctly model inclined and oblique sur-faces and features. Refer to Chapter 9 Three-Dimensional Modeling as needed for a review of construction or datum plane set up, profi les, and part bodies using standard ex-trusion, revolution, or lofting methods. Use appropriate

geometric and dimensional constraints to fully constrain each part. Apply 3-D features, such as holes, fi llets, cham-fers, ribs, and thin wall operations (as required) to create a logical, easy to edit history tree.

Use the fi nished part model to generate associated multiview drawings containing appropriate drawing views to fully describe the part, i.e., front, top, right side, and required auxiliary views. As an option, make para-metric changes to key dimensions and features in the part model and use these revisions to the model to update the associated multiview drawing.

Problems designated FOR ASSEMBLY are de-signed to be used as parts within 3-D Assembly Models contained at the end of chapter problems for Chapter 20 Working Drawings.

810 PART 4 Standard Technical Graphics Practices

3D Solid Part Models and Auxiliary View from Technical Sketches

The technical sketches in Figures 16.82 through 16.93 contain a variety of section views required to show com-plex interior details and features. Sample illustrations are included with each sketch to help in visualizing the part. Construct accurate, fully constrained 3-D solid part mod-els for each. Any available parametric solid modeling soft-ware may be used. As required with your solid modeling software, determine the appropriate method to creating, rotating, and positioning compound angle datum/con-struction planes needed to correctly model inclined and oblique surfaces and features. Refer to Chapter 9 Three-Dimensional Modeling as needed for a review of construc-tion or datum plane set up, profi les, and part bodies using standard extrusion, revolution, or lofting methods. Use ap-propriate geometric and dimensional constraints to fully

constrain each part. Apply 3-D features, such as holes, fi l-lets, chamfers, ribs, and thin wall operations (as required) to create a logical, easy to edit history tree.

Use the fi nished part model to generate associated multiview and pictorial drawings containing appropriate views to fully describe the part, ie; front, top, right side, and sectional cutaway views. As an option, make para-metric changes to key dimensions and features in the part model and use these revisions to the model to update the associated multiview drawing fi le.

Problems designated FOR 3-D ASSEMBLY MODEL are designed to be used as parts within 3-D Assembly Models contained at the end of chapter prob-lems for Chapter 20 Working Drawings.

CHAPTER 20 Working Drawings 1035

The following classic problems were taken from Engi-neering Drawing & Graphic Technology, 14th Edition, by Thomas E. French, Charles J. Vierck, and Robert Foster.

1. Make an assembly drawing in section. The bracket is cast iron, the wheel is cast steel, the bushing is bronze, and the pin and taper pin are steel. Scale: full size.

1a. Make a drawing of the bracket with one view in section. Material is cast iron. Scale: full size.

1b. Make a drawing of the wheel with one view in sec-tion. Material is cast steel. Scale: full size.

2. Make an assembly drawing in section. The assem-bly comprises two cast-iron brackets, two bronze bushings, steel shaft, cast-steel roller, and cast-iron base. The bushings are pressed into the roller, and the shaft is drilled for lubrication. Scale: full size.

2a. Make a drawing of the roller and bushing assembly that gives one view in section. See Problem 2 for materials. Scale: full size.

The problems that are given in this group have been arranged as complete exercises in making a set of work-ing drawings. Remember that the dimensions given on the pictorial views are to be used only to obtain distances of information needed. In some cases the data needed for a particular part may have to be obtained from the mating part. The detail drawings should be made with each part on a separate sheet. Drawings of cast or forged parts may be made in the single-drawing or the multiple-drawing system. The assembly drawing should include any necessary dimensions, such as number, size, and spacing of mount-ing holes that might be required by a purchaser or needed for checking with the machine on which a subassembly is used.

3. Make a complete set of working drawings for the antivibration mount.

4. Make a complete set of drawings for pivot hanger, including detail drawings, assembly drawing, and

parts list. All parts are steel. This assembly consists of a yoke, base, collar, and standard parts.

5. Make a complete set of drawings for pump valve. The valve seat, stem, and spring are brass; the disk is hard-rubber composition. In operation, pressure of a fl uid upward against the disk raises it and al-lows fl ow. Pressure downward forces the disk tighter against the seat and prevents fl ow.

1038 PART 4 Standard Technical Graphics Practices

3-D Solid Models for Assembly, Working Drawings and Design Veri cation

ObjectiveThe multiview and pictorial assembly sketches and models in this section are intended to be used to construct fully constrained 3-D solid part mod-els and product assemblies. Rendered models, photos, and parts lists are included with sketches to help in visualizing and planning product modeling and as-sembly. Selected solid modeling problems from Chap-ters 10, 13, and 16 designated FOR ASSEMBLY are included in some of the following 3-D assembly model assignments.

Nominal DimensionsAssembly and part sketches typi-cally are dimensioned by nominal size only. To achieve manufacturing realism, calculation of appropriate tol-erances, fi ts, and clearances will be required. Chapters in this text on general dimensioning, geometric dimen-sioning and tolerances, as well as appropriate appendi-ces are recommended for reference.

Use of AppendicesWhere noted on sketches, refer to the Appendix section of this text to verify thread spec-ifi cations, standard fasteners, as well as other stan-dardized part information.

Your Solid Modeling SoftwareAny available para-metric solid modeling software may be used for these problems. For assembly of existing parts, determine

the key base part and use appropriate assembly con-straints when creating 3-D assemblies. For bottom-up part modeling of individual parts, apply construction or datum plane set up as assigned to create part bodies using standard extrusion, revolution, or lofting meth-ods. For top-down modeling, plan your datum plane layout in assembly mode for part building. Apply 3-D features, such as holes, fi llets, chamfers, ribs, thin wall operations as required to create a logical, easy to edit history tree. Use the fi nished part and assembly model to generate associated multiview documentation con-taining appropriate drawing views (i.e., front, top, right side, isometric). If assigned, make parametric changes to part model fi les and use these changes to update the associated multiview documentation.

On-Line Manufacturers PartsFor standard parts, such as threaded screws, bolts, washers, spacers, bush-ings, and O-rings, many manufacturers furnish 3-D CAD models of their products online. Where possible, identify and download standard parts in order to save modeling time. Use online searches to investigate the availability of manufacturers 3-D part models. Deter-mine whether they are available in a format that is com-patible with your solid modeling software.
