How to do some subtraction and report it

[d.evans]

Can I take the measured value of one radius and subtract it from the measured value of another radius and report the result in PCDMIS?
If so how do you do that?

[Wes Cisco]

That is a pretty vague and general question. If you can construct a line thru both of them, I would create 2 intersect or pierce points and dimension the distance between them. Beyond that I need a better idea of exactly what you are working with. Can you post a sketch?

ASSIGNMENTS is the way to do it:

ASSIGN/V1=RAD1.R-RAD2.R

[d.evans]

Ive got a radius callout on the inside and a wall thickness instead of an outside radius callout. Basically they want to know the thickness of a curved wall (.100" nominal).

[Wes Cisco]

Matt's method and mine should both work in that case. Or you could use a UT mic (ultrasonic). HTH

[d.evans]

never used assignments

ASSIGNMENTS is the way to do it:

ASSIGN/V1=RAD1.R-RAD2.R

I've got the assignment command in the program, using "ASSIGN/V1 = R10.R-R9.R". This just puts the result in v1, right? If so, how do I report the result? Please be kind to my noobyness.

You need to create a generic feature. type in generic and then for the x y or z of the measured value type in V1 and then dimension this generic feature.

I believe comment/report ,v1 will do that.

[T Miller]

You could use distance and use the subtract radius option

[Underspec]

comment the variable would be easiest.

[d.evans]

not working

I believe comment/report ,v1 will do that.

I did Insert/Report Command/Comment/selectReport/type'V1' in comments.
All it reports is "V1".
Can you be more specific?

[Matthew D. Hoedeman]

You might have to look at an 'executed' report to see an actual number. When using variables in a dimension, it will show you the variable while in the EDIT screen, but then show the result when exectued. This is for editing purposes, if it didn't show the variable, you would think it was showing a 'hard' number that never changed.

d.evans,

If you are using the insert/comment menu it will do that. You have to manually edit that variable. When you manually do this, PCDMIS will ask if you if it's the variable you want to comment.

Like Underspec said. You can't put the reference in the dialog. You need to edit it in command mode. Then take your cursor out of that line and a message box should come up asking if you are referencing that variable, select yes. Then like Matt said go to report mode to see it displayed. You can also mouse hover over it in command mode and it should give a "tool tip" of the variable value.

OK, thanks for the help.

That was a LOT easier than making a generic feature and all that other stuff. I figured it would be pretty straight-forward if a variable was used to hold the value.

question though...where did you learn that comments could be used to show the value of a variable?
Have I not read my 3.7 manual thoroughly enough? curious.
