Bolt Circle with 1 or 2 Holes

[[Da...]]

I have a couple of parts which have dimensions called out as bolt circles, but there is only 1 or 2 holes on the circle. I currently have it set to report the center to center distance from the center of the part to the center of the hole(s) and then I know I need to take that number times 2. But I am wondering if there is another way to do this?

The print also calls out the position of the bolt circle, but I am instead reporting the position of the individual hole. Not sure if that is accurate?

Hi,

can you please send a sketch? I can not imagine what are you dealing with.

In both images, there are 2 holes which are listed as being on a 4.158 bolt circle. Since they are straight across from each other I am reporting the distance between them.  But on the second image, the two holes which are not right across from each other, but are supposed to be on a 3.120 bolt circle. The first image has a single hole which is called out on a 3.90 bolt circle. So I am reporting the distance from the center of the part and then manually taking it times 2 when I fill out my dimensional report. Is there a way to make a circle with only the two points? Or a way to have it come out on the report as times 2?

The second part I'm wondering about is that there are position callouts for the bolt circles, but since I can't actually create a circle with less than 3 points, I haven't been able to report the position of it. Instead, I am reporting the position of the single holes individually, but I am not sure if this is right. Will welcome any guidance. Thanks in advance!

My head is a little foggy, so deal with me 🤣

You can use "Caliper distance" and "R" value to get polar distance, or "Polar distance" to get almost same value of radius.
For opposing holes you can use any distance measurement to obtain diameter, but it would be better to report two values of radius rather than distance ( it can be offset from center of part )

We don't usually report TED, but on ASME it is different? That value is covered with TP callout - no need for reporting diameters of pitch circles
