Point at an angle

[[Kr...]]

Good morning. Happy New Year! I'm having trouble measuring the depth of a hole at an angle, point at the bottom. I measured the cylinder without any problems. The mandrel is at the cylinder's angle. How do I measure the length of this cylinder? What point and what strategy should I use? Thank you.

Can you reach to take the touch point in that depth?
If you can and you are having another feature to get beggining of that cylinder, than you can use cartesian distance - Feature1 -> touch point / Feature2 -> ideally plane from begining of cylinder.

If you can provide more information I'm sure we can help.  Got a snapshot of the drawing?  How deep a hole are we talking?  What problems are you seeing?

Given what we do know I'd do exactly as Martin suggests.

If the tolerance range is large enough. You can use a flat ended pin gage that fits freely inside the hole and take point on it. You can then just subtract distance between beginning of cylinder (plane or point) and the point on the pin from the total length of that pin gage ( You will need to tweak this depending on if the pin is sitting above or below the beginning of cylinder). I usually use prompt for operator to input total length of pin gage to allow use of different pin gages for proper fit. 

Things to be careful about: The pin gage should not be chamfered or rounded at the edges.

In order to create the point feature for the point on pin: 

1) Create secondary alignment using the angled cylinder

2) Create new point feature using this alignment and provide appropriate X,Y, Z, i, j, and k values.

3) Use programmable stop to allow operator to put a pin before taking the point (and after as well to remove pin if needed). Add good enough clearance distance to allow clearance to put the pin in.

4) Also, change the search distance before nominal for probing to avoid collisions.
