Masked Arc's

[Scot]

I am using masked arc when drilling holes. Our parts are converted Iges files from Pro-E drawings. When I window the arcs on the part, most of the time only half of the arcs get picked. Even if I window multiple times in different areas, it still won't grab all the wanted arcs. I analyzed the arcs and they are all full arcs that are the same size. Can anyone give me some input on this drilling method. Greatly appreciated.

Scot,

 

Are all your arcs in the same construction view? Is the construction depth the same for all of them?

You could run drillpt c-hook and create points in center of all the arcs you need than drill your points...

Scot,

 

Try Screen, Next Menu, Combine Views. Then try to mask on arc and see if MC finds them all.

I have found that sometimes in iges files what appear to be arcs, and sometimes straight lines are actually splines. Go to modify-conv to arcs- all-splines-done to convert these to arcs and lines. Hope this helps.

Thad has the right stuff. Anytime an IGES is brought in do 'Screen - next menu - Comb Views'. That will almost always solve the mass picking and chaining problems. I often wonder why the Comb Views command doesn't run automaticly during an IGES translation.

Thanks to BerTau. That was one of my first questions to this board.

I tried using the drill point c-hook nothing happened ?

Are you sure you had arcs on the screen and not splines?

 

Or better yet is it possible your active level was not visible and the drill points went there? Basically with this C-Hook, you call it up, and it does it, no fanfare, nothing to let you know it actually did something.
