My Architects Cad Drawings Review
Software is very difficult to review. Every piece of software is designed to do something completely different. Even if two pieces of software are designed for the same purpose, every piece of software will do it differently.
The interface is user friendly with its intuitive layout. Also, the addition of the prompt, with expert advice sets it apart from all the other similar programs. The Architects Cad Drawings installation process is clean and without any unpleasant surprises like hidden toolbars, adds or anything like that. However, the installation process takes a bit longer than expected and you actually have to go through ten steps before the installation is complete, but that can hardly be considered a downside though.
However, Architects Cad Drawings is a fairly good program considering the standard and depth of the material it provides. In addition to being effective and its great ease of use, this software makes worth every penny of its price.

Sheet metalwork application
The design of components to be manufactured from folded sheet metal is a field in which CAD systems can offer great assistance. In the case of the bracket shown in Fig. 3.3 it would first be necessary to establish the overall dimensions of the part. The second step would be to imagine that the bracket is folded back gradually as indicated in Fig. 3.4 into the flat sheet form. This shape would then be stamped from metal strip in a power press. The dimensions of the flat pattern have to make...

Engineering drawing
The first step a manufacturer must take when he wishes to make en article is to produce e drawing. First e designer will make a preliminary sketch and then a draughtsman will make a detailed drewing of the design. Since neither the designer nor the draughtsman will actually make the article, the drawings must be capable of being interpreted by the men in their workshops. These workshops may be sited a long way from the drawing office, even overseas, and so the drawings produced must be...

Douglas Dc-4 Drawings
The third Douglas DC-4 was built as an airliner but was delivered to the U. S. Army in war paint as a C-54. THE Douglas DC-4 Sky-master, which was produced for the U.S. Army as the C-54, was the most widely used four-engine transport and cargo plane of World War II, with 953 planes built in seven Army versions. Surprisingly, though, the plane didn't originate as a military airplane. Early in 1936, five U.S. airlines put up 100,000 each to help Douglas develop a new, long-range airliner, the...

Requirements of engineering drawings
Engineering drawings need to communicate information that is legally binding by providing a specification. Engineering drawings therefore need to met the following requirements Engineering drawings should be unambiguous and clear. For any part of a component there must be only one interpretation. If there is more than one interpretation or indeed there is doubt or fuzziness within the one interpretation, the drawing is incomplete because it will not be a true specification. The drawing must be...
Symbology
The ISO standards recommend that abbreviations and symbols are used wherever possible to avoid a link to any particular language. Examples of the use of symbology and English language abbreviations are as follows BS 8888 2000 ' lt ' or 'DIA' or 'D' or'd' diameter 'n' arc 'CL' centre line 'CRS' centres 'CSK' countersunk 'CYL' cylinder 'DRG' drawing 'HEX' hexagonal 'MMC' maximum material condition 'PCD' pitch circle diameter 'R' or 'RAD' radius 'SP' spherical diameter 'SQ' or a small square a...
Typical product requirement
In the example shown in Figs 23.2 and 23.3, the hole axis must lie within the cylindrical tolerance zone fixed Some advantages of using this method are 1 interpretation is easier, since true boxed dimensions fix the exact positions of details 2 there are no cumulative tolerances 3 it permits the use of functional gauges to match the mating part 4 it can ensure interchangeability without resorting to small position tolerances, required by the coordinate tolerancing system 5 the tolerancing of...

Complete cupboard is given. It may be pointed out that the two sections, Figs. 3 and 5, if drawn full size, would constitute a rod or working drawing, all that would be necessary for a joiner to set-out the cupboard by. It must also be explained that although for convenience of reference the examples are to some extent arranged in order of trades they are not constructively grouped, as in the author's works on Practical Carpentry and Joinery. Here they are placed in accord with their...
The application of welding symbols to working drawings
The following notes are meant as a guide to the method of applying the more commonly used welding symbols relating to the simpler types of welded joints on engineering drawings. Where complex joints involve multiple welds it is often easier to detail such constructions on separate drawing sheets. Each type of weld is characterized by a symbol given in Table 26.1 Note that the symbol is representative of the shape of the weld, or the edge preparation, but does not indicate any particular welding...
Surface finish specification in the real world
When it comes to drawing a part to be manufactured for real, it is not necessary to add an SF specification to each and every feature. The vast majority of features do not need them since the common manufacturing processes achieve the SF required and more often than not, the SF is unimportant. It is only in a few instances, where a surface is functionally important, that it is necessary to define a SF. Indeed, specifying a SF is the exception rather than the rule and I have seen many drawings...

The clearance in a 'close-running fit' is smaller than that in a There is no out-of-roundness in a hole drilled by a new sharp drill. The IT5 tolerance range is larger than the IT4 tolerance ranee. One of the values of the 'H' or 'h' tolerance classes is always zero. The tolerance class c 11 is the negative of class C11. The GT symbol for symmetry is an 'equals' sign. A datum must always be given in a GT box....
Analytical Figure Drawing
Now let us introduce some variety into what we are doing and at the same time open up the possibilities. In Part One, the sphere and box were roughly the same size. Start introducing proportion into the drawing in a controlled manner. Proportion is the relationship of various elements in a drawing which include size, tone, textures, quantities and differences that give expression or character to the work. Proportion can be the size of the head to the body or just simply a large form to a small...
Production drawings
The following three typical drawings are included as examples of draughtsmanship, layout, dimensioning, and tolerancing. Figures 31.1 and 31.2 show a pulley and a shaft, and illustrate some aspects of general dimensioning and tolerancing. Figure 31.3 shows a partly dimensioned elevation and plan view of a proposed gear-box cover, with a wide application of theoretically exact boxed dimensioning and the associated positional tolerances. To emphasize this style of dimensioning, other dimensions...
A Complete Drawing Details Of A Precast Concrete Building
Component sub-component and assembly drawings A component may be defined as any item used in a building which emanates from a single source of supply and which arrives on site as a complete and self-contained unit, whose incorporation into the building requires only its fixing to another component or components. Thus, a window is clearly a component, as is a manhole cover, a door, a section of pre-cast concrete coping, a mirror. So, for that matter, is a brick. A brick wall would be an...
Roof Types
The Couple Close Roof Fig. 2, has the feet of the rafters tied together by nailing the ceiling joists to them, which strengthens the roof considerably, thus enabling it to be used for wider spans than the previous form. The Collar Beam. Roof, Fig. 3. shows the fie or collar placed higher up in the roof, to increase the space in the room below. When this type of roof is used it is necessary to have heavier common rafters than in the preceding types. The Collar Bolt and Tie Roof illustrated in...

Chain Dimensioning
The drawing page and into the eye of the reader. The valve dimensions follow the dimensioning convention laid down in the future ISO 129-1 2003 standard. Tolerances have been left off the figure for convenience. In this case there are two datum features. The first is the left-hand annular face of the largest cylindrical diameter, i.e. the face with the 30 chamfer. Horizontal dimensions associated with this datum face use a terminator in the form of a small circle. The other datum feature is the...
Geometric tolerance classes
The table in Figure 5.13 has shown the various classes of geometrical tolerance. These are only a selection of the most commonly used ones. The full set is given in ISO 1101 2002. Row 1 in the table in Figure 5.13 refers to 'GTs of straightness'. The symbol for straightness is a small straight line as is seen in the final column of the table. An example of straightness is seen in Figure At the periphery of the section, run-out is not to exceed 0,15 measured normal to the toleranced surface over...

Boston III The initial British order for 300 DB-7Bs was followed by the transfer of 240 French-ordered DB-73s built by Douglas, and 240 that Douglas sub-contracted to Boeing. Tankage increased from the DB-7A's 240 U.S. gallons to 394 gallons to allow bomber operations over occupied Europe from England. Starting in mid-1941, many Boston Ills were drafted into the U.S. Army Air Forces. Boston M Later DB-7Bs procured for...
Splines and serrations
Splines and serrations are repetitive features comparable to screw threads. Similarly, it is not necessary to give all the details of the splines or serrations, the symbology does it for you. The convention is that one line represents the crests of the serrations or splines and the other the roots. This is shown in the hypothetical drawing in Figure 3.17 where there is a spline at the right-hand end of the gear drive shaft. A note would give details of the spline. The standard ISO 6413 1988...

Slotted nuts and castle nuts
One method of preventing nuts from coming loose is to drill the bolt and use a pin through the assembly. Suitable nuts are shown in Fig. 16.22. Slotted nuts are available for sizes M4 to M39 and have six slots. Castle nuts are also available with six slots between sizes M12 to M39 and eight slots between sizes M42 and Table 16.14 Double coil rectangular section spring washers to BS 4464 Table 16.14 Double coil rectangular section spring washers to BS 4464
Forms And Structures
The hand is not a flat, two-dimensional shape without volume. It is a dynamic, three dimensional body form, energetic and complex, each of its forms and structures interrelated. In this chapter we will look at it from various angles in space and depth, noting its curves and rhythms and examining the bulk, sizes, shapes, and masses of its individual parts and their relation to the whole. The main masses of the upper and lower ami are good example of the principle of contraposition one form being...

CAD considerations
The addition of status coding is a useful adjunct to the issue of CAD files also, the status reference being added to the layer naming convention reference A practice might also be maintaining multiple copies of a drawing file on different computers, or in different sub-directories on the same computer some may be back-up copies in case of hard disk failure some may represent different stages in the evolution of the design. For internal purposes a practice will need to know more about a drawing...
Functional and nonfunctional dimensions
Although every aspect of a component has to be dimensioned, some dimensions are naturally more important than others. Some dimensions will be critical to the correct functioning of the component and these are termed functional dimensions. Other dimensions will not be critical to correct functioning and these are termed non-functional dimensions. Functional dimensions are obviously the more important of the two and therefore will be more important when making decisions about the dimension value....

Cylindricity
The combination of parallelism, circularity and straightness defines cylindricity when applied to the surface of a cylinder, and is controlled by a tolerance of cylindricity. The tolerance zone is the annular space between two coaxial cylinders, the radial difference being the tolerance value to be specified. It should be mentioned that, due to difficulties in checking the combined effects of parallelism, circularity and straightness, it is recommended that each of these characteristics is...
Theoretically exact dimensions Fig
These dimensions are identified by enclosure in a rectangular box, e.g. and are commonly known as 'Boxed dimensions'. They define the true position of a hole, slot, boss profile, etc. Boxed dimensions are never individually toleranced but are always accompanied by a positional or zone tolerance specified within the tolerance frame referring to the feature. Symbols for geometrical characteristics Symbols for geometrical characteristics A straight line. The edge or axis of a feature. The...

Example of drawing a small hand vice
A common artefact in any workshop is a small vice. Such a small engineering vice is shown in Figure 3.1. The main body of the vice is a stubby 'U' shape in which a movable jaw is positioned between the two uprights. The movable jaw is actuated by a screw which is rotated by a small bar. Although the drawing is 'busy', the different lines help to make the artefact jump out from the page. This has been done by the use of different types of line thicknesses thick and thin and different types of...
Tapers
In Fig. 14.18 the difference in magnitude between dimensions X and Y whether diameters or widths divided by the length between them defines a ratio known as a taper. Taper X Y 2 tan length 2 For example, the conical taper in Fig. 14.19 and may be expressed as rate of taper 0.25 1 on diameter. The ISO recommended symbol for taper is and this symbol can be shown on drawings accompanying the rate of taper, i.e. 0.25 1 The arrow indicates the direction of taper. When a taper is required as a datum,...
Third angle projection
The difference between first and third angle projection is in the arrangement of views and, with reference to the illustration in Fig. 4.4, views are now positioned as follows View B from the left is placed on the left, View C from the right is placed on the right, View D from above is placed above, View E from below is placed underneath. Study the rearrangement shown below in Fig. 4.4 and remember the above rules because it is vital that the principles of first and third angle projection are...
Draughting conventions associated with threads
Threads are so regularly used on engineering drawings that recognizable conventions are required to save draughting time. Figure 15.12 shows the convention for a male thread. The thread runout along the shank of the stud is indicated by a line drawn at 30 to the thread axis. The minor diameter of the thread is shown by parallel lines and in the end elevation the projected circle is not continuous. The break in the inside circle distinguishes the end elevation of a male thread from a female...
Lettering symbols and abbreviations
Many drawings are microfilmed and this causes a problem of legibility when drawings are blown up again to their original size. Thus, it is recommended that the distance between adjacent lines or the spacing between letters or numerals should be at least twice the line thickness. There are six ISO standards would you believe it on lettering alone they are under one standard. The six parts of ISO 3098 refer to general requirements part 0 , the Latin alphabet part 2 , the Greek alphabet part 3 ,...
True lengths and auxiliary views
An isometric view of a rectangular block is shown in Fig. 11.1. The corners of the block are used to position a line DF in space. Three orthographic views in firstangle projection are given in Fig. 11.2, and it will be apparent that the projected length of the line DF in each of the views will be equal in length to the diagonals across each of the rectangular faces. A cross check with the isometric view will clearly show that the true length of line DF must be greater than any of the diagonals...
