Rationales for drawing changes that are noted in the rev block often use these abbreviations for brevity (e.g., "DIM 14.00 was 12.50; added default TOL info to T/B; added leader lines to F/D; added alternate hardware IDs to P/L; added alternate alloy to L/M"). FIM: full indicator movement: See also TIR. FL: flag note, flagnote
When part definition is defined mathematically via a solid model, the assertion that one cannot interrogate the model—the direct analog of "scaling the drawing"—becomes ridiculous; because when part definition is defined this way, it is not possible for a drawing or model to be "not to scale". A 2D pencil drawing can be inaccurately ...
A fabrication is made up of many different parts. A fabrication drawing has a list of parts that make up the fabrication. In the list, parts are identified (balloons and leader lines) and complex details are included: welding details, material standards, codes, and tolerances, and details about heat/stress treatments. and also [2]
The toleranced feature is the real surface (orange line segment) corresponding to the plane indicated by the leader line of the specification on the nominal drawing. Specified datum: The red line illustrates the associated datum plane which is the minmax plane with external material constraints as defined in ISO 5459:2011.
A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...
Leader, in distributed computing, the process selected after a leader election; Leader, an appliance sub-brand of Haier; SR Leader class, an experimental British steam locomotive; In engineering drawing, a leader or leader line is a thin line connecting a label or dimension with the part to which it applies
