How can I improve my engineering drawing?
9 Tips for Better Engineering Drawings that Save Time and Money
- Tip #1: Dimension only critical & measurable features.
- Tip #2: Communicate hole tapping needs with thread size and depth.
- Tip #3: Consolidate call-outs when multiples of the same feature exist in a view.
- Tip #4: Communicate assembly intent of critical features.
How can I get good marks in engineering graphics?
Master each type of assembly and dis-assembly drawing, first practicing in free hand but also doing it with tools. Practice and improve your visualization skills as this is an important way to score in the questions for projections. Study in a group; pick a question, have each friend sketch the answer and compare.
What are the four different methods of projections used in engineering drawing?
There are four main types of projection methods used in mechanical drawing in order to convey information such as geometry, dimensions, tolerances, material and finish….Let our resources save you time and money!
- Orthographic Projection.
- Axonometric Projection.
- Oblique Projection.
- Perspective Projection.
How do you take care of technical drawing instruments?
Always cover the surface with cardboard or thick paper. Keep the drawing board in a safe place when not in use….Always keep your tee-square clean.
- Do not use any sharp object such as razor blade or knife on their edges.
- Keep them away from fire.
- Always keep them in a safe place immediately after use to prevent leakage.
What should be on an engineering drawing?
Requirements of engineering drawings
- Engineering drawings should be unambiguous and clear. For any part of a component there must be only one interpretation.
- The drawing must be complete.
- The drawing must be suitable for duplication.
- Drawings must be language-independent.
- Drawings need to conform to standards.
Which of the following is correct for 1st angle projection?
If an object is placed in 1st quadrant such that one of the surfaces of object is coinciding with horizontal plane, what is the correct position of views from the following? Explanation: In the first angle projection the projections of object is taken by placing object in 1st quadrant.
What is difference between first angle and third angle projection?
To get the first angle projection, the object is placed in the first quadrant meaning it’s placed between the plane of projection and the observer. For the third angle projection, the object is placed below and behind the viewing planes meaning the plane of projection is between the observer and the object.
Why do you have to take care of your drawing tools properly and regularly?
Proper care and routine maintenance of your hand tools and power tools makes any home improvement or repair project easier, safer and more successful. Proper tool care also saves you money because the better they’re cared for, the longer they’ll last.
What is the rule of orthographic projection in civil engineering drawing?
According to the rule of orthographic projection. To draw the projection view of a 3D object on a 2D Plane, the horizontal plane is rotated in the clockwise direction. We will implement this rule to draw engineering drawings in 1st angle and 3rd angle projection systems.
What is the left hand side view in engineering drawing?
The left hand side view is drawn on the left hand side of the front view. Similarly, the top view (plan) is drawn at the top of the front view. Engineering drawings, being one of the many forms of technical communication, have to fulfill some accepted standards.
How to identify first angle projection?
If the object is placed in the First Quadrant for viewing the projections, the angle of projection is identified as First angle Projection. In First angle projection the Object is placed in between the Viewer and the Plan. In simple terms if the Order is Viewer – Object – Plan is First Angle Projection.
What are the three stages of engineering drawing?
Usually engineering drawings (of real life objects) are prepared in three stages; sketches, handdrafts and detail drawings. This sequence is not very binding but most workers find it very useful to work in that order. 2.3.1 Sketches
