The standard views used in a three-view drawing are the top front and the right. The Engineering Drawing common to all Engineering Trades is one of the book developed by the Core group members as per the NSQF syllabus.
Automotive Design Technical Drawing Mechanical Engineering
For drawing projections of solids one has to frequently draw projections of lines either parallel to the HP or the VP and inclined to the other with an angle that is between 0 to 90Similarly sometimes the projections of plane surfaces Perpendicular to one and inclined to the other are required to be drawn.
. Up to 5 cash back Engineering Drawing 2nd Edition by. ENGINEERING DRAWING GRAPHICS PROJECTION OF POINTS AND LINES SECOND FLOOR SULTAN TOWER. This module will cover the non-drawing portions of a print.
Engineering drawing practice for schools 81 colleges bureau ofindianstandards manak bhavan 9 bahadur shah zafar marg new delhi 110002. All units are as indicated Not preferred. ANSI Standard US Engineering Drawing Sizes.
Up to 4 cash back Architectural drawing sizes are based on the ARCH scale while engineering drawing paper sizes are based on the ANSI scale. Ans85-When a straight line is inclined to a plane it will meet that plane produced if necessary. I have received the attached cut sheet from the manufacture.
When I look at this cut sheet it seems like the motor size they have specified is too small. A drawing that contains all information of an object Drawing is important for all branches of engineering. Rotate the line AB about the end A keeping f the inclination of AB with VP constant till it becomes parallel to HP.
1988 first published march 1989 first reprint december 1990 second reprint september 1992 third reprint october 1998 0 bureauof indianstandards. Line AB has its end A 25 mm above HP and 30 mm in front of VP. This rotation of the line will bring the end B to the second new Position B2.
Understanding BHP and HP. Having precise vocabulary is key when working with large quantities of expensive materials or when aiming for exact specifications. Engineering drawing graphic portion The information contained in the drawing itself will be covered in subsequent modules.
AB 2 is the new position of the line AB when it is inclined at f to VP and parallel to HP. It is drawn with reference to XY line. Usually a number of drawings are necessary to completely specify even a simple component.
An engineering drawing is a type of technical drawingthat is used to convey information about an object. D-size paper for architectural plans is 24 x 36 inches or 6096 x 9144 millimeters while D-size paper for engineering plans is 22 x 34 or 5588 x 8636 millimeters. Mark a point a at a height h mm above XY and a at a.
Roll of engineering graphics Visualization. Location of the company or agency. A title block will typically appear in the bottom-right corner of a drawing and contains information related to the drawing including.
So Engineering drawing is a starting point of all engineering branches such as Mechanical Production Civil Electrical Electronics Computer science Chemical etc. While drawing auxiliary projections auxiliary reference lines are used for representing projections. Engineering Drawing Formats Menu.
The first four parts listed above provide important information about the actual drawing. The company or agency that prepared the drawing. I took the BHP 489 and divided it by the motor efficiency 875 to get a HP 56.
When it comes to documentation and standardization there is a specific set of engineering abbreviations that has made communication in the field of engineering uniform. Reference plane is used by engineers to show their projection of objects and the plane on which the projection of objects like points lines planes solids projects called plane of projectionin practice Orthographic projection uses two principal planes ie horizontal plane HP and vertical plane. What are reference planes and what is their use in engineering drawing.
I am in the process of reviewing a shop drawing for an AHU. Get full access to Engineering Drawing 2nd Edition and 60K other titles with free 10-day trial of OReilly. Now the HP is rotated in the clockwise direction for 900 and is obtained in vertical position.
The point in which the line or line produced meets the plane is called its trace. Engineering Drawing Inch Format Sizes. The line of intersection of Horizontal plane HP and Vertical plane VP is the main reference line x-y refer Figure 21.
2 Vertical trace-The point of intersection of the line with. Engineers work internationally to design most of what is around us. Orthographic Projection When the projectors are parallel to each other and also.
Width in Length in Horizontal Zone. Drawing is the standard used in engineering and technology because many times the other three principal views are mirror images and do not add to the knowledge about the object. Engineering ANSI and Architectural drawing format sizes.
Engineering Graphics Universal language for engineers. 1 Horizontal trace-The point of intersection of the line with the HP is called the horizontal trace. 5 Side Views When the observer looks at the object from side ie from his left-hand side or right-hand side the view obtained is called side view SV.
International Organization for Standardization. The ability to understand the information. There are of course other drawing.
Individuals who drew checked and approved the drawing and the date they did so. The Engineering Drawing common to all Engineering Trades as per NSQF 1st Semester is the outcome of the collective efforts of experts from Field Institutes of DGT champion ITIs for each of the Sectors and. Engineering Drawing - Projections of Cone with generator on HPwe are explaining the projections of a cone when one of its generators on HP and that generator.
A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. The lines of intersection of auxiliary planes with principal planes are auxiliary reference lines. Of HP and VP.
The projections will be seen as given in Figii. Rotate the line AB to make it parallel to HP. Engineering drawing is a graphical language of an engineer to convey ones ideas most effectively easily conveniently and with high speed.
The drawings are linked together by a master drawing or a. SV is seen on the PP.
