Using Intventor 2011 can you use Ordinate Set to dimension diameters?
I am trying to use it on a section view from the center line but the dimensions displayed are only half the size of the actual diamter (this is obvious because I'm dimensioning half the part realistically). Is there a setting I am missing that allows Inventor to recognise it as a diameter?
See attached drawing.
Your IDW file requires all accompanying files, ITP's and IAM's.
If you RMB (Right Mouse Button) when you select the arc for dimensioning, you then have a choice of selecting Diameter from the pop-up dialogue box.
I don't know any way to accomplish what you want with ordinate dimensions. But if you dimension using linear diameter dimensions, you get close. When placing a standard dimension from centerline to radial feature, right click before placement and choose Linear Diameter, as shown in the attached image. A quick look through dimension styles didn't reveal any way to set this up as a style, so you have to change it manually each time you place a dimension.
Hope that helps.
You can change it in the Application options - Drawing tab. It would be easier if it could be altered in the style though.
Don't hold your breath... I'm not aware of any drafting standard that allows this technique, and I think it could be confusing to anyone reading the drawing.
@sbixler: One good reason to use this technique is to provide endpoints geometry for CNC lathes which typically expect diametrical and not radial data. This is very important when communicating such things as an o-ring groove in a face or other small details on a large part. As long as the diameter symbol is shown on an ordinate dimension, it is understood that the origin of the ordinate is the axis of rotation.
And yes, we are all Inventor users and will not hold our breath waiting for Autodesk to provide the same functionallity that has been around in 2D AutoCAD for 20 years. Instead, we will forge ahead with work arounds that will fail when the next release comes out... ;-P
I had similar problem dimensioning something of very big radious. Center of the arcs (8 or 9) was not realy anyware. It was only a theoretical point and ot was far far away form the view.
I was fighting with ordinate dimensionning. finaly I did get somewhare. I will post some jpg in the ewening.
I also Igree with that that such kind of dimension is very usefull. not only for automatic lathes but also for normal lathes.
Whan someone is fabricating what you had designed he schould have given dimensions of things he is able to masure.
In such case it is obwiouse that dimeter is fisicaly masured.
In the meantime I post drawing of something that is currently being made.
I think it was dome in solid edge.
