I am working with a forge part with no datum structure. It is calling for a profile of .120 u .09 to itself. (+.09/-.03).
My though is that the simplest way to approach this is with an iterative alignment (machine to part), then go to town with auto feature vector points (or would it best to use measure point and why?). And do a best fit alignment of all and only the profile point then dimension it.
I am working offline. I see the deviations when dimensioning which and should be at zero. So what I am gathering is my alignment needs adjusting?
Q:
- It won’t let me upload a picture it is prompting me this message "Upload failed due to your usergroup's upload quota. This file will require 50.2 KB but you only have 17.1 kb of 1.50 MB remaining". How do fix this so I may upload a snip.
- Will I get arcuate results?
- How would I double check myself?
- What are the cons of using a read-point for an iterative alignment? I love the idea of removing the manual probing completely. But is it and will it be aureate?
