how to reset ordinate dimension to 0

[ken]

I've created a 2d drawing from my 3d sheet metal drawing, and when I try and start an ordinate dimension, the starting point does not start at 0 but instead at some other value like .120.  This only happens for one view (like the back).  I tried creating a new drawing from scratch and interestingly, the one axis I was having trouble with (y axis) now starts at zero, but now the x axis is starting from an offset.  What is going on here, how to fix?

Hi ken,

For each drawing view, the first ordinate dimension you apply sets the 0,0 point for all other ordinate dimensions in that view. In other words that point becomes "zero" for both X and Y directions. You can later identify this by hovering over it, it should show an additional glyph. If you delete all ordinate dimensions on a view and "start over" it should allow you to pick a new 0,0 point. Again, this is on a per-view basis.

Let me know if this is not the behavior you are seeing.

Ah, this makes sense and corresponds to the things I've tried.  The problem I'm now having is I don't know how to put the first point at the location I need to, since the origin area where this needs to happen is a rounded corner, so neither the end of the x or y drawing meet at the imaginary intersection point where 0,0 should be.  How can I do that?

You can try one of two things.

1. Hover over the start of the fillet, then the end of the fillet, then move your cursor out to that imaginary intersection. You should see green dashed lines, and it will "snap" to that intersection. However this requires that the edges leading to your fillet are orthogonal in the drawings sheet.

2. If that doesn't work, you can create a sketch in the modeling workspace and ensure there is a line or intersection at that point. When you update the drawing, you have to turn on the sketch. Once you can see the sketch you can snap to that point. Note that for this to work, the sketch plane needs to be parallel to the view plane, for the view you are using for your ordinate dimensions.

I hope one of these two options works for you.

Perfect!  Suggestion #1 worked and I'm back up and running.  Thank you so much for answering my questions!

Another option is to use the edge extension geometry feature to create the intersection point you need, and then start your ordinate dimensions from there.

Thanks, the snap method above didn't work for me but this seems to be the "right" way to do it!
