angled hole on angled face

[wirehead]

i have been trying to measure the position of these holes with no luck..i have tried cylinders, circles, and even using pins in the holes for cylinders.. nothing seems to be working..
how can i get the 316.22 dim .. and position

Got CAD?

Autocircles with sample hits on the surface around the hole should do the trick.

The photo is quite grainy, what are the datums defined in the FCF?
I see D is the intersect point of the two hole axii, which makes the 316.22 distance from front plane...
I also see a outer plane or possibly diameter as a datum towards the left of the part, but can't make out the letter...

Too low resolution on the picture to be able to see anything definitive. Is your 316.22 dim the distance from the 'center point' to the cylinder's intersection with the angled plane?

ok, got it, does that work for cylinders too.. i need to create a point a the center of the part to measure the angled length.. i was going to intersect at the center of the part using a cylinder

Sorry for the pic here is another .. The print was updated yesterday, but my problem is still the same [a-b] is the center line of the bores[ATTACH=JSON]n460480[/ATTACH]

Where is it ?

G should be a plane, so Iwould try a pierce point between the cylinder axis and the plane G, then dimension the distance between this point and the upper plane, and repeat it on the other side.

For the position, we need the same kind of picture, with the position .

Is datum G an actual feature, or is that Datum constructed solely from the intersect points of those four cylindrical axis lines?
This is a sectioned view... is this part round? are there other holes spaced about a circular pattern basically along a cone? What does the FCF say for position? it looks like applies to multiple holes...
Although you gave us a better picture of the view, you still have left out critical elements of the drawing. Without more info, we still can't help.
you can even type in the position controls, if uploading another image is too cumbersome.

example:
3x 1/4" - 20 UNC-3A
[Countersink] diameter of 0.300, depth 0.150 with a 0.020"radius
[TP][x.xxx][A(m)][B(m)][C]

-G- is the midplane between -C- and -D- -AB- is the line between the bores -A- and -B-

Could you post the unreadable text which is up to the position ?
I think that there's too much informations on the location, because the boxed 130 is constrained by the horizontal distances and the angle.
With what I can see, I would locate only the circle at the intersection of the cylinder and the plane, but I think I would call the designer...

hey thanks for the help.. i have it working for me now.. sorry for the crappy resolution, but the print is in plotter format and it sucks to print...
