Reference a hole’s internal sketch plane

[gmintenko]

MY QUESTION:
Does anyone knowhow toreference (or use) a hole feature's internal sketch plane to define a new revolved surfaceusing ProE/WF2 FoundationAdv.


BACKGROUND INFO:
I'mmaking my own API style pipe threadUser Defined Feature (UDF)and want minimize the number of user selected references (E.g. keep it to onlydrill a surface and an axis).I have defined the profile of the threadusing a sketched hole with coaxial placementbut would also like to create acosmetic pipe thread (e.g. with a variable diameter). Ihave seen that this cosmetic pipe thread can be created using a revolved surface and I like the result. THE PROBLEM is that tocreate a revolve, I need a sketch planeBUTI don't wantmy UDF to require another reference. If I could reference and usethe initial hole's internal sketch planethe UDF would bevery clean andsimple, very easy to use. Life wouldbe good!

If your hole has an axis, you can create a "sketch plane datum" on the fly when creating your revolved surface.

I can create extra datums but I would like to avoid that if possible because it wouldcausethe UDF to requiremore input references (Ican't create a datum plane about an axis alone, it wants something else before it lets me click 'ok'. I can reference a piece of geometry to complete the planebut thatsometimes causes the modelto have errors depending on where the UDF is placed).


I'm essentially tryingrecreate what is happening in this file:2006-07-28_172607_cosmeticThread.zip.The modelcame from one of the udfs posted by aaroyopr at this thread: [url]http://www.mcadcentral.com/proe/forum/forum_posts.asp?TID=30 432[/url]. Notice how the feature tree is very clean with very few datums. If youeditsketch placementfor the revolved surface you'll see that it uses some internal datum thatcomes from the hole. Can anyone explain to me howthis was done?

btw


how to make a surface to be shown on drawing with yellow edges like a thread


I fetched nptf in udf and there is a revolve cut and this surface as a thread
