would like that inventor could detect U, V, W and V hole bottoms, so that ISO 15768 requirements on holes notation could be met.
Inventor has currently 2 limitations preventing it to fulfill ISO 15768 requirements. If this idea would be implemented, one of the two limitations would be addressed.
1st limitation: inventor cannot distinguish between U, V, W and V (underlined V) hole bottoms
2nd limitation: inventor cannot document the LH (left hand thread) WITHOUT the Thread Class indication because the two information are collapsed in the <THRC> thread property, thus the notation marked with B is technically not possible to be obtained
If you vote for this idea, please consider to vote also for the other one addressing the other limitation.
Behind this apparently very simple issue there are quite intensive thoughts. Long story made short:
1. the ISO 15768 norm itself is NOT unambiguous, sometimes leading to critical situations: the ambiguity between V holes and V holes on the callout (figure 5 and 7 on page 5 of the ISO_FDIS_15786_draft.pdf*) leads to the critical situation explained in the Note C.
2. even if Inventor is much more capable than what the norm requires on certain aspects, it cannot fulfill ALL basic norm requirements on basic aspects (notation as in the Note B is not possible: the thread tolerance will be anyway visible on the drawing)
1st limitation: critical 2nd limitation: irritating
The issue is known to Autodesk development and is being discussed since more than one year. In this moment the reference developer is Jason Hetu, and for what I understood from him they are "working on another hole project to fix some of the hole note, and thread table information". According to what he wrote THIS idea is already in the backlog. Of course additional votes can only help speeding up the process.
Please, vote up!
* this document is a draft, if anybody has the final document he is welcome to clear the point
@@Dan, do we get in trouble for posting a norm draft in ideas?
