TYPICAL or TYP notation on drawings 4 - Eng-Tips ANSI Y14 5 used to dictate the use of X instead of TYP, but ASME Y14 5-1994 now states that X "may" be used, which seems like TYP is allowed once more It is still poor practice in my opinion, as specifying the number of places removes ambiguity As for symmetrical parts, any qty question is answered by the symmetry mark on the centerline
ANSI Y14. 5M 1982 and use of TYP - Eng-Tips I often use "TYP" for weld symbols (although the external and internal drafting standards where I work are all but non-existant) I think with weld symbols, it is a lot cleaner Also, I would argue that in some applications, it makes more sense to use "TYP" without the number of places specified
TYPICAL or TYP notation on drawings 4 - Eng-Tips As I understand it The "TYP" statement was and perhaps still is an architecture standard and not a mechanical standard The "TYP" callout was often used in wall sections to reference typical or common elements of a section In mechanical engineering, you often see this callout on hole dimension and the like
What does TYP (Typical) mean on a drawing? - Eng-Tips Using TYP is an old habit that is still hard to quit The dimension and applied tolerances for this feature are the same for all other features of the same size and shape [green]"I think there is a world market for maybe five computers "[ green] Thomas Watson, chairman of IBM, 1943 Have you read faq731-376 to make the best use of Eng-Tips Forums?
use of typ. on a drawing 3 - Eng-Tips You may even use TYP 5 PLACES as a local note (make sure you call out the number of PL)as long as it is clear It is a good practice to have seperate drawings for L H R H to document say tooling changes on one that may not be needed on both drawings ,(tool hole etc )it just gives you better control of Drawings
Text Lisp - Autodesk: AutoCAD | Eng-Tips Save it somewhere as "CT lsp" In Autocad at the command line type (load"ct") and press enter Still at the command line, type CT and press enter Have some text in the drawing At the CT prompt, select the text you want to change, then type the text you want to replace then type the new text For instance, replace "a" with "a typ" ; "CT
Multiple Hole Pattern Defintion - Eng-Tips So, per a previous post of mine, we've discussed that fact that TYP is a nonstandard way of indicating multiple instances of a dimension and a preferred method is to actually state how many times the dimension is applied (e g 24X R 125) So I'm working on a fixture drawing that holds 4 164 pin connectors
THRU, THRU ALL and Continuous Feature 1 - Eng-Tips THRU - I'd say necessary when it's not otherwise obivious that the cut hole goes thru the entire part I'm perhaps a bit generous in my use but having been the idiot searching a drawing for the hole depth only to finally realize it was a thru hole I use it a lot
Drafting Standards, GD T Tolerance Analysis - Eng-Tips Typ is not the approved (ASME Y14 38-2019) abbreviation for Typical It should be 'TYP' Also, TYP has been suggested to not be used for repetitive callouts but rather a value with an X; ie 24X "Wildfires are dangerous, hard to control, and economically catastrophic " Ben Loosli
FULL R vs R - Drafting Standards, GD T Tolerance Analysis mkcski, I see your point I wonder how he "2X R" symbology for a slot or any feature on which it is applied should be interpreted in terms of inspection Given that what controls the radius is the as produced width, as stated in the Genium Manual and as presented here by CH, and if the slot geometry is toleranced with +-, does that mean that uniformity of the
