drawing - gives incorrect dimensions - am i going crazy???

[Anonymous]

Hello all,

I don't know what I'm missing here, but I do have this problem often. In the drawing file, I want to put an isometric view or some other custom view just so you can get an "overall" view of the object. However, trying to put the dimensions on that causes very strange numbers to come up!

For example, this is a plain isometric view of my object. It has dimensions (long edges) of 20mm by 20 mm. Yet in the drawing it puts these dimensions as 16.33 (which I guess has something to do with sqrt(20)), but why does it do this? I want the real values!

What am I doing wrong?
Thanks in advance for your help.

The drawing sheet represents a 2-dimensional drawing surface. In an
isometric view, you do not get true length dimensions. What I think you are
after is showing 3D dimensions on a 2D sheet. I do not know if Inventor can
do this.

Stephen is correct. We don't support 3D dimensions in an iso view.

You can ovveride the value by:

1) Double-click the dimension on the value
2) In the Dimension Tolerance dialog, check the override value checkbox
3) Enter the desired value and OK

Hope this helped...

Ah, I see. I don't know, I just assumed that would be a useful thing to have for this view. But of course I don't want to put all dimensions on an isometric view, so I can just override the values and enter them manually.
Thanks for your help!

Yep ... can be done I suppose, but sounds like something other then sound
documentation practice to me. Hope I don't ever get to where I think
overriding dims is a good idea.

ok, ok, it's bad practice.
i can put dimensions on proper 2d views and just have little isometric view in the corner (no dimensions) so that people can see what it looks like (not everyone i am working with is always looking at technical drawings).

[Anonymous]

I find that any interaction with the shop is done while focusing on the
isometric view. It has been very beneficial in speeding understanding of
what they're about to build. Some welders know how to weld but have not been
through blueprint reading and for them it is indisposable.

Yes, it's true, people like to see the isometric view, they can instantly grasp what the object is! That's why I wanted to do such a *bad* and *crazy* thing such as putting a few dimensions on that isometric view 😉
Thank you for your kind post!

It's only "bad" and "crazy" when you use a CAD application that is incapable
of placing accurate dimensions on an isometric view. It wouldn't be "bad"
and "crazy" to do this in another application.

Doing so is a negation of an associative, parametric design software. I've
done so under duress, changing the color in the hope that I would never
damage myself by putting out a drawing with an incorrect dimension on it.
It should embarrass Autodesk that it fosters such a shoddy, even by
yesteryear standards, practice. There are so many ways to deal with the
requirment in an adequate (@dXX), if not elegant (show model dim or
annotation), manner. So much for leading edge technology. Roll eyes,
shake head, go for beer.

I'm just puzzled because I thought what I wanted to do seemed reasonable, I was surprised that Inventor doesn't support this.

[Anonymous]

Yes, I too am worried that if I start overriding dimensions then things will get out of control and I'll end up with designs with incorrect dimensions all over them.
Are you saying that Inventor should support this kind of dimension on a 2D view, or that they should not offer overrides?

[Anonymous]

I think they should support dims on 3D views, but I also think there are a
bunch of other enhancements I'd rather see first, like: strikingly
accomplished BOM & SM modules might do for starters.

Oh ... "...they should not offer overrides?" ... I think they should indeed
allow us to be idiots whenever we might feel the need to demonstrate such a
disposition.

Why are you being so critical?
I was not saying that they should not offer them, I was asking for a clarification of your previous post.
And I'm not an idiot, just perhaps not as experienced a user as you.

I'm sorry, it was not your previous post, it was "defaults". I was asking for clarification when s/he said

I apologise for the mistake.

[Anonymous]

No ... didn't mean that ... I mean I should be allowed to be an idiot if I
choose to. It wasn't a personnel attack I think everyone should be allowed
to "have it their own way" (ah ... the freedom to be an idiot ... love it)
and I can only say what I would probably do and don't have any desire
whatsoever to tell anyone else what they should/should not do or disparage
them for doing it. I've probably done every idiotic thing you can imagine,
and being 4 days older'n God probably a bunch you can't imagine. Please
don't take any of my opinions as an attack because I don't ride a tall
enough horse to engage in that sort of nonsense. Sorry for any misunderstand
I'm responsible for.

Yes, I am an idiot sometimes though. I am sure experienced users would shudder in horror at my Inventor designs. But I do like Inventor a lot, and I want to get really good at it. This discussion board is so valuable to me, the help I've got from here is so great! I am the Inventor "expert" at my work, ie. I am alone, and so if I have problems, I have no one at work that can help me. So this discussion board is really great for me.
I am sorry for misunderstanding you too!

[Anonymous]

Unfortunately, "Splatt" is not a witty moniker but instead my real surname 😉
It gets worse, of course my nickname is Flic (common nickname for Felicity), so I'm commonly known as "Flic Splatt"!
