Sketch Angle Issue

OK, class, we are going to draw a cone (revolve feature). Now, follow
closely to these instructions. This cone is going to be 7" long. Make
the big end radius a dimension of .18". Make the small end radius a
dimension of .12".
Sometimes, we want to know what the angle will be (not included - just
on the side). Go ahead and throw that angle dimension on there? What
did you get? If you make the cone less than 7" long, you will probably
get an angle dimension. If the cone is longer than 7", the dimension
will probably not be an angle.

Is it just me or this a serious issue? Of course, there is a
work-around. Make the cone 6" and then put the angle on there and then
make the length grow accordingly. If we are not careful, this could
bite someone!

Arlan,

I can't wait until we can post to a newsgroup in our own voice instead
of typing. Anyway I can't reproduce your issue. I have to be screwing
up the steps. Are you leaving the profile open before you dimension or
are you fully enclosing the revolve? Are you using a centerline like
the old days or not using a centerline? When you say you don't really
want the angle dim does that mean you want it there but just to be
driven?

Arlan,

I got 0.51310298deg.

Everything works as it supposed to be. I think it's you, not a SW
ussue.

 

Yes, I am leaving the profile open. I am using a centerline just like
the good ol' days. Yes, I want the angle dim to be driven. How I
found this issue is because I needed to figure the taper on a piece
that was 40.5" long. I have explained this 3 different ways so far and
I just can't seem to do the explanation correctly! OK, picture this:
A plate that is 10" long and you mic one end and it is .12" thick. Mic
the other end and it is .18" thick. It has a taper (obviously!), but
we want to know the angle. Lay the part flat on the granite, and the
angle we want to know is from the granite (square to the world).
I ended up getting the angle I wanted (.08488257°) by shortening the
part and I found that the 7" length was the 'break over' point.

I don't know if using a centerline was the proper way to start this,
but it is the way I draw...

Of course, it's me! What else could it be?

I was able to bounce this off of a friend in another state and he was
able to reproduce my issue. He said bob z. should get at it on the
newsgroup, but bob z. is LAZY.

I am probably leaving off the most important information:

swx2006
sp4.1
dell 8400
pentium 4 - 3ghz
1gb ram
ATI VIDEO CARD <------yeah, baby!!!!
logitech mouse
dell keyboard
samsung 19" CRT

 

If I put the angle in the sketch, between the angled line (the one that
makes the tapered face on the cone) and the centerline, I have no
problems at all (2006, sp 4.0).

I figured that maybe I didn't understand where you were trying to put
that angle dim (in the sketch, in a drawing, or what?)
I did learn that if I show the sketch after the feature has been made
and put a reference dim between the same line and centerline but in the
model mode, I can still dim the angle, but not the inside angle - it
comes out as 179.8 no matter what I do. However, that has nothing to
do with the 7" cutoff - it happens if I make the cone 2" long.

I didn't have your problem on SW06 SP0 or SP4.1.

well, good ol' bob z. begs to differ with you. you probably ride a
harley...

is this what you guys are drawing? bob z. got it the first try.
here is a screenshot:

I too attempted to duplicate this problem and found the same results
that you did. I then looked at the tools/ options/ document
Properties/ units and found the default degrees was set to 0 places.
When I increased the number of decimal places the dimension tool then
produced the desired results. What could make this even more
confussing is that this variable can be set with the drawing template
so that one time it could look like the results are fairly inconsistent
between seats.
