Is there a quick and easy way or a website to find the x-y dimensions from 0 center of a bolt hole pattern? Thanks.
Calculating bolt hole circles?

i have a dro that does the calculation for me, works great ... some times i forget and put in numbers IE for 6 holes for 360degrees which actully results in 5 holes ,(0 degrees and 360 is the same hole
ive scored a circle in to the part and sectioned it for 1/4 the of the circle , protractor score the holes i want then with vernier score a grid from a square fixed edge , done well id think the holes would be with in a few thou's

I just wrote a macro for my CAD program that draws them. These drawings took less than a minute each to make. It took me longer to convert them to black on white and JPEG file format for display.
The top shows a 4" bolt hole circle with seven 1/2" diameter holes and the first hole at 270 degrees. I just input the numbers with keyboard or mouse and then click on the center of the circle. A few seconds later it is done. I can use any diameters, any number of bolt holes, and any angle to the first hole. The cross hairs allow dimensions to be snapped to the hole centers: it would take more time to add all the dimensions than it took to draw the bolt hole circle but if I did, it would be spot on to better than tenths.
The bottom half shows some fun I have when I input ridiculous parameters. Hole diameter greater than the circle diameter and severely overlapping holes.
Here is another fun drawing with wild parameters. These two have 100 overlapping circles.

And if you look REAL close at an analog signal,
You will find that it has discrete steps.
