First assy componet origin

[Anonymous]

When the first componet is placed into an assy, it doesn't
automatically put part 0,0 with assy 0,0. It seems to put part
centroid with assy 0,0. Is there a switch to make part 0,0 the
default? I know I can move it, but why? Who would ever think to not
insert at the origin?

I agree. I think IV should at least have a DEFAULT placement so that the
origins are automatically aligned.

I think there may be method in Autodesk's madness.

A while ago there was a discussion arising from tapped holes showing
improperly in that the thread pattern showed outside of the solid block.

The problem arose because the part was WAY off the origin. By
constraining it to be closer to the origin, the display problems went away.

I would expect this is why IV re centres the parts.

Having said that, I agree that a switch that permits matching part
origins to the assembly origin, and truly (as in the move and rotate
command don't override it) grounding would be a nice feature.

I always unground it and do 3 flush constraints from the origin folder of
the part to the origin folder of the assembly, one for each basic plane, YZ,
XZ, and XY.

I also always move the part to 0,0,0 but by a easier (maybe a little quicker
too). I do it by RMB on the part in the assembly browser, chose Properties,
Occurance tab. Change the values in X,Y and Z offset to 0. Click O.K. and
your done.

I just checked several of my assemblies that I know the first part has
not moved or been constrained by me to the assembly origin. In all
cases the first part's origin is in exact alignment with the assembly
origin. AFAIK IV has always inserted the first part with the assembly
and part origins mating. I have experienced parts that were well off
the assembly origin, but that was because the part was not created
around its origin.

I suppose there are a number of reasons for certain behaviors.
Although I think it would be odd for someone to sketch a part far from
origin.
Also, if the part origin is visible, it's position is included into
the centroid calculation. Draw a part 100' from origin, turn origin
visible and make it the first part into an assy and part will be 50'
away from assy origin.

I just build them as Master sketch parts and they automatically go to the right place in
the assembly. 8^)

The parts created in-placing in an assembly are often far from the origin
and is the reason that when I create a part in-place, I just project the
relevant geometry then go to the ipt constrain it to it's own origin and
finish it there. An option to constrain to origin in assemblies might be
useful, I'd think, since I have to do it manually now.

Or moved off with the move command in the assembly.

Kirk:

Presumably you leave the part grounded.

I guess you're lucky enough not to have accidentally rotated the
grounded part a degree or so and have whacked views in the idw.

If you have opened a new assembly and you use the PLACE PART command to
place a new component into the assembly, Inventor has always grounded the
placed component such that the component's origin is coincident with the
assembly's origin.

If you are following these steps and you are getting a grounded placement at
any other location - please send me the models and the exact steps you are
using.

As noted however, if you create parts in-place - your origins may not be
coincident.

Excellent tip, thanks. I thought maybe I could save the 0,0,0 property
setting in the template. Either part or assy... but no.

That's my problem! I have been dragging parts into the assy from
explorer instead of using "place part" ! I have dual screens and
working from explorer with thumbnails on the second screen has become
a habit. If it had been random, I might have figured it out, but they
come in perfectly centered on a bounding box of the parts extents. I
suppose knowing that might come in handy some day. Thanks Gary, I'm
finding my frustrations being replaced with experience.

Hmm! Interesting.

I must say that my most common technique is to:
1/ Create and save a part
2/ Select the part's name in its browser and Ctrl-C
3/ Start an assembly
4/ Ctrl-V the part

Perhaps this technique, which is clearly not the one you mentioned,
causes the initial part to insert at random locations.

Thanks for the heads up.

I must say, though, it would be really nice to have the option of
automatically grounding the origin planes. Because the 'Grounded'
option permits moving and rotating, it is not quite robust enough and I
go through the routine of ungrounding and adding three constraints to
every assembly I create.

I use the Place Part method but often constrain it anyway. If it gets moved
accidentally sure whacks the idw's ... Re: questions on the NG about
"...can't place dims..." and stuff.

Can it get accidently moved if it is grounded?

Yes if you try to move or rotate it using the toolbar. You will have to
unground it and then constrain it to the origins.

Yes, I see. It can do some big damage. It's a good ideal to constrain
the first piece, and a switch to do that would save about 2 minutes
per assy. Lets see, 150,000 users, 300 assy a year x 2 minutes is 171
years.

I'm glad to see other users agree.

Now if we can come up with a real jazzy way to describe this so that
Autodesk marketers can use this as a selling feature in R9, maybe it
could happen 😉
