Alignment to offset holes?

Stephen McMillan
Hi all. First post. Sorry if it's a rookie question.

I want to do a Plan-Circle-Circle alignment.
The first hole is the x0 y0 origin.
The second hole has some given coordinates, say x8.0, y4.0.

I don't want to have to calculate the angle and use the "Offset angle" in the "Rotate to" field.
I also don't want to use an iterative alignment.

Any ideas?

Thanks,
Steve

  • Both are correct depending on the nominals, basic or open. If the offset value is basic while the other axis is open dimension then your auto nerds are right. The print will define the datums and hence the proper way to build the gage or your alignment.

    Not to belabor a point, but both can't be correct if one method yields a good part but the other says the same part is bad. And the idea that both axes are valid for the construction of the datum since they're both basic I don't agree with - basic dimensions are also used to define exact locations, most notably when defining a gage line.
