Inventor Assemblies - Aligning Model with XYZ Axis and vica-versa.

[PafecDOGS]

Hi, we've discovered quite a complex assembly of ours from a while back isnt aligned with the XYZ axis properly - we think when the first part was inserted it wasnt auto-grounded (as an aside we keep having to re-tick the box "Place and ground first component at origin" in the assembly tab, it does not seem to stay ticked) and somehow got rotated before it was grounded. Now trying to create a drg of this component, although we can set the front face to a flat face to create the ortho views, when we dimension it we get weird dimensions due to the axis mis-alignment. In the past with this kind of thing, what i tend to do is unground the grounded part in the assy and mate the parts origin planes to the assy origin planes, then delete the mates and reground the part, but of course if a drg already exists of that assy, realigning the model makes the drg views go askew. I was wondering if there is anyway to realign the XYZ axis to the model rather than realign the model to the axis ...?

Hi Pacef,

unground the first not aligned component, re-alligned correctly with assembly Origin planes  it would be better.

But if you don't want it, you can procede this way (not reallign the xis, but reallign the views for the drawing).

(Hoping that you have one model face, or workplane to refer orthogonally...)

Hope that it can helps you.

You can align the views like is described in post #2 above.  If you want to align the model to the origin planes..... there is a tool for that.  First "Unground" the first component, then click the Assemble> Ground and Root Component tool (itsunder the "productivity" flyout.

Yes, that is what my supervisor did, but you'll notice, as in your clip, that when you realign the face to the front view, your XYZ axis are misaligned. The drg you created then gave you the required flat orthoganal views, but if you tried to dimension certain parts of those views you created, you'd get some very odd dimensions because of the XYZ issue ...

Hi, that was certainly a tool I didnt know about, that was quite useful thanks, although my question is can you align the XYZ axis to the model and not the other way round which is what the tool does (although much quicker than i did mating the planes etc)

Nope, the origin planes and axis are fixed..... they are not editable.

You can only resize them and rename them, but you cant move them.

You can RC and choose "annotation plane" > use sheet plane.

Note sure I follow you there.  Here is what I see when I RC on an origin plane.

Sorry Kirk!

I refer to other post, about dimensions on the drawing.

It's possible to allign dimension from rotated model right clicking while positioning the distorted dimension

Do it right.. unground/reconstrain the iam/ipt.

Awesome!  I didn't even know you could do that from the assembly view...duh.  Simple and quick...and CORRECT.  Thanks!!!
