Over-dimensioning refers to the practice of designing or specifying components, structures, or systems with dimensions or capacities that exceed the actual requirements for their intended use. This can lead to increased costs, unnecessary weight, and inefficient use of materials. While it may enhance safety or durability, over-dimensioning can result in waste and may not be the most effective approach in terms of resource management. Balancing safety and functionality is crucial to avoid over-dimensioning.
What else can I help you with?
How is geometric analysis used in dimensioning?
I did your mom.... a favor by making you.... a sandwich:))
What is a masonry modular dimensioning?
Masonry modular dimensioning is a system used in construction that standardizes dimensions for masonry units, such as bricks and blocks, to streamline the design and building process. It involves using a consistent module, typically based on the size of the masonry units plus mortar joint thickness, to facilitate accurate layout and reduce waste. This approach enhances efficiency in construction, ensuring elements fit together seamlessly while allowing for easier planning and execution of masonry structures.
What are lines that cross over each other called?
Just because they cross over each other doesn't mean they aren't still called lines.
Why would it be innapropriate to dimension to a feature on a surface that is not perpendicular to the line of sight?
couple of reasons.... if you are drawing and dimensioning with a computer program the dimension will be inaccurate... If it is mechanical drawing then the fabricator would not have enough information to accurately measure the component. ie a circle turned a few degrees away from perp. would appear to be an ellipse. and may actually dimension that way
What does 4 and 12 mean in regards to a roof pitch -------run and ------- rise?
rise over run. That would be a 4" rise for every 12" run. In other words, 4" vertically over 12" horizontally
What does OA mean when relating to dimensioning?
18" o.a.
What is meant over dimensioning a sketch?
For putting to many dimension on top of the dimension!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
4 What types of numeric constraints may be applied to sketches?
Things like General Dimensioning and Auto Dimensioning
Which dimensioning method permits the accumulation of errors?
Tabular dimensioning
What is chain dimensioning?
It show dimension of given dig. Ex. length meter etc. > chain dimensioning as opposed to datum dimensioning. chain dimensioning: 4 holes in line on a drawing, first hole position dimensioned from the edge, remainder dimensioned from the centre of the previous hole. datum dimensioning: all holes dimensioned from the edge. the cumulative tolerance build up on the chain dimensioning allows for greater overall tolerance build up.

What is over-dimensioning?
Over-dimensioning refers to the practice of designing or specifying components, systems, or structures with dimensions or capacities that exceed the actual requirements for their intended use. This can lead to increased costs, material wastage, and inefficiencies, as larger or more robust solutions are often more expensive and may not provide additional benefits. While it can enhance safety margins, excessive over-dimensioning may detract from optimal performance and sustainability. Balancing adequate safety with cost-effectiveness is crucial in engineering and design.
What are methods of dimensioning?
Methods of dimensioning include linear dimensioning, which specifies the size and location of features using straight measurements; angular dimensioning, which indicates angles between lines or surfaces; and radial dimensioning, which is used for circular features, providing the radius or diameter. Additionally, leaders and notes can be employed to clarify specific details. These methods ensure clear communication of sizes and relationships in technical drawings.
What is baseline dimensioning?
Baseline dimensioning is a method of dimensioning in technical drawings where all dimensions are referenced from a single baseline, reducing the chance of errors due to accumulation of tolerances. It helps to maintain clarity and consistency in the layout of dimensions on a drawing.
How are dimensioning standards used?
they are used by showing where it is
3. What is the difference between chain dimensioning and datum dimensioning?
Chain dimensioning involves placing dimensions in a linear sequence, where each dimension is referenced from the previous one, which can lead to cumulative tolerances and potential inaccuracies. In contrast, datum dimensioning establishes a reference point or surface (datum) from which all other dimensions are measured, ensuring consistency and precision across the entire part. This method reduces the accumulation of tolerances and enhances the reliability of the dimensions. Overall, datum dimensioning is generally preferred for critical applications where accuracy is paramount.
What is contour dimensioning?
Contour dimensioning is a method of dimensioning a part by specifying the lengths of its contours or outlines. It provides an overall description of the part's shape and size without specifying the individual dimensions of every feature. This method is often used for parts with complex shapes where detailing every dimension would be impractical.
