[Summary]Assembly Constaint Quick Keys

Original Question:

A little irritation has driven me to ask a simple little question. When I
assemble a part using mate or align plane to plane or flat surface to flat
surface I am usually give a request for the offset which I usually enter
with a bogus value, then I redefine that last constraint by clicking in the
offset distance box and changing the offset to a orientation or coincident
constraint. Is there anyway to set these to orientation or coincident
constraints when I am initially asked for the bogus offset? This has
bugged me for years but I have been to lazy to ask. I have tried typing in
c or ctrl - c for coincident and o or ctrl - o but nothing I have tried
works. Any suggestion from you assembly gurus out there? Oh by the way yes
I am still on 2001.



Sincerely,

Conclusion:

There hasn't been an acceptable answer yet. I am too anal to use zero for
the coincident option and obviously that doesn't work for orientation. And
as far as using the snap to I would rather zoom and pan in and out on parts
than switch back and forth between the move and place tabs in assembly
constraint dialogue box.

Thank for the responses, it sounds like the majority of use just deal with
it and push on.

Good afternoon Ryan,



Try CTRL+ALT+MMB to spin and CTRL+ALT+RMB to pan will allow you to
dynamically position the new component relative to the main assembly. This
is invaluable to locating these components correctly. You may still be
prompted for offset distance. However, if you get the new component's
surface "close" to the assembly surface, Pro/E will mate or align them.
"Close" will depend on the size of both the new component and the existing
assembly. This method is often easier than typing in the offsets or 0.



The Pro/Help topic is: About Freeform Mouse-Driven Component Manipulation



Good Luck,

Mark

There is a config that when set is supposed(it hasn't worked for me) to

produce the following, When in the "component placement dialog box" move

the component as close as possible to desired placement (the config that

you set is a ratio) if the component is within the ratio(distance) it

will not ask you for an offset-I think this config is supposed to be

used in conjuntion with another one-sorry that I'm not that specific.

Also if you have AAX you can drag specified pre constained components,

bolts etc to a hole and it will snap in place-no need to manually

constrain,

P.SSmiley Frustratedorry here are the configs



comp_snap_dist_tolerance "put your numeric value here"

auto_constr_offset_tolerance put your numeric value here"



If you just hit return, you'll get an offset of zero, which gives the same
results as a coincident constraint. I have no idea what Pro uses to
determine whether it thinks a mate or align constraint should be coincident
or offset; seems it usually picks the opposite of what I want, just as when
I use an orient constraint, it usually makes the wrong choice between mate
and align. However, if you leave your offset of zero, and find later that
you actually do need an offset, you can easily do it with modify instead of
having to do a redefine... for whatever it's worth.

Re: [Summary]Assembly Constaint Quick Keys

Cormac's mention of config settings prompted me to look for others. I
found one that seems to do the trick:

auto_constr_always_use_offset never

I'm using Wildfire 1.0, M140... don't know if 2001 has this option.
