turn off dimension doubling

[mwasson034]

I can't figure out how to turn this off. Each time I go off either the center dot or center line, it doubles. AI tells me to make it linear. Ok.. then why do I have to uncheck linear on each measurement?

Another thing. When I am doing a drawing and start cutting lines.. why does it make me have to make it make up hundreds of dimensions to make it fully constrained? Even if all of the fillets are made at the same time and connected to constrained lines. It wants dimensions are just dumb.

What do you mean by it doubles?

Hi!

If you select a Center line when placing a dimension, Inventor will set that dimension as a diameter instead of a direct dimension (radius)

Try this:

Turn the center line as normal line

Place the dimensions

Set the line as center line again

Check the video:

You can also achieve what is wanted when creating the dimension by RMB then DESLECTING "LINIER DIMENTION" in the popup, this needs to be done for every dimension as and when it is created

Why should I have to do any of these things? That's the problem. Even not going off the center line and going of the center "dot" does the same thing. So I have 200 measurements going off the center and on each one, I have to right click and uncheck linear? I already said this in the original post "Paul Mason" in the photo. Do that 500 times and tell me how fun it is.

I have to make it a "normal" line to get my measurements off which totally throws off everything and then when I'm done.. I change it back? What the heck is the point of a center line then? 

[mwasson034]

You know. You make a line that is 2" long and it says 4 with an arrow pointed two times the distance of 2".  It's in the photo.

Because, by using a centerline in the sketch, you told it you want to do those things.

Why are you using a centerline in the first place if you don't want it to behave like one?  Getting the "linear diameter" effect is one of the two functions that sketch centerlines have in Inventor.  The other is that a sketch centerline will be automatically selected as the axis for a Revolve feature, but only if there is a single centerline in the sketch.  You have two, so that doesn't apply.   If you don't want one of those two effects, then you have no reason to use a centerline in the sketch.

Hi!

The point of having a center line in 3D model is, for example, it's handy to get diametric dimensions for revolve features like shafts, cones, etc, etc... where the diameter is a more important information then the radius:

If you want to use it for other purposes, that's ok, just turn it into a normal line, place your dimensions, and set it to centerline at the end... no big deal.

This is a throw back to the days when we used a Drawing Board and Pencil to do the drawings in good old 2D.We would draw the centre line and one half of a revolved part. and it STILL is the accepted way to dimension a revolved part, and YES I am old enough to remember and have used drawing boards

Then what do you use If you use the dot in the center. It does the same thing. I think I should still be able to turn it off. When I have 50 dimension on one side alone and would rather mirror them than draw them all, I think I should be able to turn it off.

[mwasson034]

I get that, but that just throws me off sometimes. I just wish I could turn it off is all. Can't go off the center dot either.

[mwasson034]

Well at least someone gets what I am sordove talking about. Yes, I did that also. But in this case, it is just to mirror fifty different dimensions instead of drawing it all out on both sides.

I'm also trying to figure out why, it needs dimensions measured out of air (basically to nothing), to get it fully constrained. A dimension I would have never thought of or think anyone in their right mind would need.

[dan_inv09]

What do you mean by "center dot"?

Do you somehow have it treating the origin point on a sketch as if it were a centerline?

(If I do a dimension from a point to a line then I can make it do a linear diameter but the line is the center - how are you doing a (default) linear diameter with the point as the center?)

No it doesn't.  The "doubling" effect you're describing only happens if you use a centerline, and is one of the main points of the centerline function.  You have absolutely no reason in what you are describing to use a centerline at all.  You already answered your own question when you said that turning it back into a normal line prevents the doubling.  That is the answer.  You don't need the functionality of the centerline, and in fact it gets in your way, but you're insisting on using it anyway for some reason.  

[hollypapp65]

Don't dimension to the centerline.

Dimension to the endpoints or center point of the center line.

You don't need center line in model sketch.

You can add center line in drawing if you want.

How you dimension in the model don't need to be the same as how you dimension in drawing.

I started on drawing board too.  Then AutoCAD, MDT, Inventor.  It's not the same.
