Thanks for the input and yes it is the symmetry symbol. This should give me enough information to explain should someone question why I removed it.

I have a drawing (drawn 1988 interpreted per MIL-STD-100)using feature control frames. The symbol used is symmetry and after the value the word "TOTAL" is used. The drawing is being redrawn to dimension & tol standards ASME Y14.5-2009. I cannot find a reference to the word being used and...
Patrick,
They went with the XPS and although I tried, was not able to provide any input. Now that the XPS is not working out and after a visit from our SW VAR they are looking to upgrade to a laptop workstation machine. They seem a little more amenable to input from the users this time and...
All,
My work computer is being upgraded and listed below is what I am being offered. I have been asked for input (immediately) and am wondering if anyone sees something here that either would be a good fit or if something can be approved upon. At this point we are running SW 2014 SP5 and are...
Hope this is the correct thread for this question.
I have a welded sheet metal part. The part has two features at the bottom that will have a vent disc welded into place basically making this an inseparable assembly. Incoming QA cannot check the dimensions of the slots after the disc has been...
We have a printed circuit board assembly being developed that has space rated components and specific notes for processing and testing a space rated board. We want to make a test board using commercial available parts (cheaper and less lead time).
Space board would be XX54321 (no dash number...
I have a sheet metal part with a flange on each side. On the opposing outside faces of each flange are a series of countersunk holes, 6 on each side (using hole wizard). Each series of holes are thier own feature in the feature tree.
When I dimension thses holes in the drawing using the hole...
Is the total overall reference dimension for repetitive features required to be on the drawing? Example 4 X .250 (=1.000) or 4 X .250. I recall reading somewhere that the reference dimension is either no longer used or optional. Cannot remember where I read it. Any help would be appreciated.
Thanks
The 2 versions of ASME Y14.5 1994 and 2009 read the same in 2.3.2 and the referenced paragragh 1.6.1. 2.3.2 deals with displaying the tolerances of a certain distinct feature. Thinking about it (should have done that in the first place), a common C'bore hole has 3 distinct features; thru dia...
Is it permissable to use a mix of 2 and 3 place decimal dimensions units (inch)in the same callout example 3 place decimal for thru hole tolerance and 2 place decimal for c'bore diameter and 2 place decimal for c'bore depth. ASME Y14.5 2009 states that in using bilateral tolerances all units...
I have been asked if it is acceptable to take a group of note numbers (in sequence) on a drawing and put them on one line "4-11 DELETED", instead of the customary listing each note number individually on it's own line, with the term deleted after the number. (we use term deleted, not removed)...
Thanks,
I do not have ASME Y14.4m either, but it got me thinking, and that might be dangerous.
I do have the Genum "Modern Drafting & Standards Manual" and in there it defines pictorial drawings as either isometric, trimetric or oblique drawn views.
It includes a paragraph referencing "photo...
On a few occasions I have been asked to insert/embed a jpeg file onto a drawings sheet and with the exception of one time have told engineering that this is a practice I would like to stay away from for the following reasons:
1. Clarity, graphics files typically do not have the best resolution...
