How do I dimension a small angle nicely? |
|
|
Hello,
I have a problem with angle dimensioning. When I try to
dimension a small angle, <0.5°, ProE usually gives me
lengt dimension instead. I very carefully select two lines,
not line+vertex or vertext+vertex, but I still get a lengt
dimension.
If I have a 0.2° angle I could dimension it 89.8° or
90.2° but I don't want that.
Can anyone explain to me howto do this, if possible?
regards
Bjorn

Let me try:
Start out with the angle larger, even 45 degrees, then drag one leg to the desired
dimension or modify the dimension value to make it exactly what you want.
I'm not sure if it could effect the ability to create small, fractional angled
features, but if the above fails, change the default ANGLE_TOL to a small, several
decimal place number. |

You need to zoom up on it, probably as much as possible, then pick the two
lines as you normally would.

You can do this by changing the config.pro option minimum_angle_dimension
controls the minimum tolerance under which Pro/ENGINEER assumes colinearity
for driven dimensions. Setting the option below the angle in question fixed
this for me..

Thank you for the answers |
Just zooming in didn't work for me, although I only zoomed
so far that everything went black (background color) and
then some more.
I found a parameter that could be added to the config.pro,
minimum_angle_dimension , and set it to 0.01.
That seems to do the trick. I don't know what the default
value is.

Can't you just exaggerate the size of the angle in your sketch - add the
dimension (if it
really is important) - and then modify it to the desired value ....
I hyperexaggerate most sketches.

I do the same thing to stay away from snapping references in sketcher. Both
methods ~ turning off intent manager and exaggerated dimensions ~ address this.
But there's a third way, as well. When trying to produce a small angle close to a
snapping reference, right click to disable 'point on entity' constraint, or any
other constraint that prevents creating a small angle. This is like turning off
intent manager, but does it selectively. If you'd like a disabled constraint
reenabled, right click when it appears again.
There's also something you can do if you find that end points of lines or centers
of arcs are jumping to a sketcher reference from what seems like an inch away and
'stick' hard to the reference: you can turn down the snap strength with the option
SKETCHER_REL_ACCURACY, another misleadingly named option. I think the relevant
values are between 1 and zero, .5 being like 50%. With .1, you have to be almost
on top of a snapping reference before the snap takes place and it 'sticks' only
weakly to the reference. This sensitivity setting can save a lot of frustration
with erratic snapping in sketcher. This option may have been around for a while
but undocumented and I only discovered it in the last year. Given a lot of
people's frustration with intent manager working poorly, I'd like to popularize
playing with this option's values to see if it makes it more useful for people.

Not sure whether you are doing this in sketcher or drawing mode
(others seem to have assumed sketcher but I couldn't find a specific
reference to it in your message). FWIW, I find with my setup in
drawing mode, that I have trouble double-selecting circles to
dimension a diameter. (it seems to insist on selecting the centre).
Bit of a nuisance really and a collegue with virtually the same setup
doesn't have the problem at all. We even swapped various config/setup
files but the problem stayed with me.
Zooming in is a way around this but I find I have to zoom in close
then back out a little way for it to work. Just zooming in doesn't do
it. I thought perhaps that technique might work for you.

Hmm. I've had similar problems; it just tells me it can't place the
dimension. I've sorta got an idea it's related to the pick / highlight /
pick sequence. Seems if the picks are quick; almost a dbl clk, it will
fuss, but if I pick, move the cursor away from the arc segment then come
back in to pre-highlight and pick it works (though it could just be my
imagination; it's an ever now and then thing). Could be graphics card
related (?). |

Interesting .... I doubt the graphics card issue in my case because my
colleague had the identical machine including graphics card (they were
bought as a pair). I also ran for a while on a different machine with
different card but the same problem. I've tried slow picking but it
didn't help in my case.
Even the first pick will pick up the centre instead of the arc ....
it's almost like the pick box is too big, but it would have to be
pretty enormous and I don't seem to have trouble with other picks.

Don't know for sure, but I think I've tried picking very deliberately
(slowly) and still got the error (it's kind of random and I'm not sure if I
see or just imagine a "pattern" to it). I *think* it might hinge on moving
away from the arc segment so it's not pre-highlighted and then coming back
in. I could be confused, though. 8~) |
