What does it mean to hold a dimension?
In architecture and some other disciplines, you can also add “HOLD TO” to the dimension, to indicate that other dimensions may have to be adjusted slightly to make this dimension correct.
What does dimension in a drawing mean?
• A dimension is for size and position (of the designed/modeled shape). • A DIMENSION is a numerical value expressed in appropriate units of measurement and used to define the size, location, orientation, form or other geometric characteristics of a part.
What does hold mean engineering?
While dealing with day to day engineering activities It is required to issue many engineering drawings or documents by placing a “HOLD” in the drawing or document. So initial revision of documents is issued by placing “HOLD” for items that are not yet designed as final or vendor confirmation is not yet received.
What is short break line?
Short break lines are thick, wavy solid lines that are drawn freehand. When either of these break lines is used to shorten an object, you can assume that the section removed from the part is identical to the portions shown on either side of the break. (thin and long with a zigzag) (thick and short, wavy freehand)
What is a true dimension?
True Dimension-: True dimension is the measurement, which is required after the machining. This is the value that ought to be accomplished after the machining. ISO- Constraints-: When degrees of freedom of geometry have been taking up by a predictable combination of measurements and fixed geometry.
What does a circled dimension mean on a drawing?
This notation indicates that the dimension should be used for inspection purposes. This practice is normally used in the ISO standards.
What hold means?
HOLD. Honest Open Logical Decisions (mathematics education; New York, NY)
What held down?
Definition of hold down (Entry 2 of 2) transitive verb. 1 : to keep within limits hold the noise down. 2 : to assume or have responsibility for holding down two jobs.
Is there such a thing as a hold dimension?
Hello, I’ve come across some drawings for cylindrical parts where some of the diameters are called out as Ø.345 HOLD. I’ve never heard of a hold dimension. Is that like, ‘do your best to keep the diameter at .345’ or what? Thanks! : “Hold” dimension?? I’ve seen those too.
What is the science of dimensioning and tolerancing?
Geometrics is the science of specifying and tolerancing the shapes and locations of features on objects. Once the shape of a part is defined with an orthographic drawings, the size information is added also in the form of dimensions. Dimensioning a drawing also identifies the tolerance (or accuracy) required for each dimension.
What are the components of a standard drawing?
A standard componentin this drawing standard is an unaltered component for which no detail drawing is included because the part is to be procured from a source which fabricates that component to that source’s specifications. The three components of a set of working drawings are: 1. Detail drawings of each part to be fabricated 2.
Why do you need to include an assembly drawing in a drawing?
An assembly drawing shows how a collection of parts, standard components, and subassemblies fit together into a finished product. Every set of working drawings should include at least one assembly drawing. If the product includes multiple entities which are not connected together, then an assembly drawing for each entity should be included.
