Nice comeback Kenat - he kinda had that coming. I liked your sketch and didn't think it needed that kind of critique, either.
Keep up the good work, 'far from least...'

That's a good question about the word 'drill'. I have always used the term "DRILL POINT" to describe the deepest part of the tap drill hole. The second method used if it's important to control the drill point depth is to use a cross section and in the hole callout just state "TO DEPTH SHOWN IN...
Thanks for your support, bTrueblood. Dimensioning bolt circles IS a different animal, no? I don't have a good answer for vc66 but I know that adding the 360 dimension to a round thing is not required. Yet, it IS assumed which make's it overconstrained in the linear world, but done often in the...
All right - one last time - please pay attention. This is why we dimension ALL of the spaces in a hole pattern:
If you have five 72 degree increments and they are all controlled by the same general tolerance they CAN'T accumulate! Get it? Somewhere at least one of them would have to be out of...
vc66 - that was just so lame - I bet you make faces at people behind their backs, too. Do you consider change just for the sake of change a good thing. I bet I can name quite a few things that YOU do the same way as you always did that should NOT be changed.
mint julep - Have you ever played the shell game?
ALL dimensions must be met simultaneously. You state that the angle between 4 and 5 is not conforming...that's a show-stopper right there. It does not matter if some of the dimensions are conforming some of the time - ALL dimensions must conform...
If you want to control threads accurately, you don't do it by telling the machinist what drill to use - you insoect with a thread gage. Period. Drawings should not be confused with process sheets. Telling someone which drill to use does not ensure the thread form. Do you want to measure a drill...
KENAT,ewh,
Remember, you are measuring a part as it exists in it's final configuration, NOT writing an operation sheet for a machinist. The 5th dimension exists even if the machinist does not have to make the move. 4 x 72 allows accumulation where as 5 x 72 actually limits the fifth space as...
I have to respond to MechEng2005 especially on this: You don't count the MOVES that it takes to create a 5-hole pattern; you coubt the SPACES. There are 5 spaces between 5 holes and they ALL matter in your dimensioning. That's how you keep accumulation limited. If all of the 5 spaces have a...
Good Morning,
Does anyone out there have a list of settings that minimizes the work that the video card has to do? I have a sun station that is good in every way except that when zooming in and out or spinning a big model, the task manager shows 100%. I have made the changes that I thought would...
We are having some hot debates here pertaining to detailing piping drawings. When you show a pipe that slopes into or out of the paper, you can only show the 'flat' dimension on the drawing (east-west, let's say). This does not show the 'true length' because you still have to trig this out by...
