I have an arc thats giving me a lot of trouble. Please help me!
I am using CAD with an iterative alignement but not CAD=Part. The mojority of the part is completed and dimensioned accurately. The 7.25 Rad that mates with the bobmb surface is also datum -E- and is required for the TP callouts in several areas.
I tried this method that Mike N. posted (thank you Mike) on 06-06-2006.
To measure a partial arc/radius:
1. create a "measured" circle
2. edit (F9) the circle and add additional hits and edit the "best fit math type" to "FIXED Radius", edit the NOMINAL DIAMETER, check box to "regenerate hits", when prompted "equal spacing" answer YES
3. ctrl E the feature to execute it and re-capture the measured hit points
4. dimension the "location only" of the fixed radius circle/arc
5. edit dimension tol's to print
6. create an alignment and set origin on fixed radius circle
7. (if using CAD skip this step) F10/Parameters>Probing> enable polar compensation for the active workplane
8. with joystick measure more individual/separate points on arc radius (if using CAD use "vector point" skipping step #7)
9. dimension individual points using the "PR" polar radius function
10. F10/Parameters>Probing> turn off or disable polar compensation
I changed workplanes and completed number 1. I completed numbers 2 and 3. I did number 4 and 5 but was not sure if it applied to the part I am working on. I don't if I satisfied the requirement. I think number 6 went well, I just inserted alignment and translated x,y, and zto new feature. I didn't do seven because I'm using the CAD. I did 8 and 9, I am assuming tha PR is the sam as PRAD in the location dimension dialogue box. And 10, what does this do for me at the end of all of this. I don't get it.
Sorry for the long post. The part is on the plate and I'd be happy to try anything. See the attached screen shot of the print area I'm working with
