Ordinate dim to sketch entities

[Anonymous]

We're having a problem with Ordinate dimensions.  When we dimension to a radiused corner, we dim to the "implied intersection" of the two lines, rather than to the center of the radius.  We make a sketch with the two "tick marks", then dim to the intersection of the tick marks.  Ordinate dimensions are not allowing us to pick the intersection:  it wants to put two (or three) dimensions, one to each end of one or the other tick marks (see attached).  We use Ordinate dims about once a year, but I'm sure I remember being able to ordinate dimension to the tick marks.  Anyone know anything about this?  IV R2010, SP0

The ordinate dimension command does not let you select endpoints/midpoints,etc.. during the initial steps..

Just delete the other 2 if you don't want them.

However if you go back and add a member Inventor will let you pick the end/intersection point. Same goes for arcs.

During the 1st step you will get multiple ordinate dimensions.. But if you add a member later you can pick the middle/start/end of an arc.

That the way I do it.. My first round of selection is only features that will create a single ord dim.. Then I go back and add member for any arcs/midpoints,etc...

See my reply to the other thread you started on this topic.  In Inventor 2010, you can place ordinate dimensions directly to an implied intersection of two lines (I just did it a few minutes ago to create the images I posted).  You might want to uncheck the App Options > Drawing > Enable ordinate dimension geometry selection box and see if that makes picking things easier, or at least more intuitive.
