end point on a circle

[CH]

while selecting holes for a driling toolpath i have the selection filter set to end point and center. the problem is that when i select a circle i am picking up an endpoint?

i dont think i should i be picking up an endpoint on a circle? should i?

I know that i can un select end point while picking holes but i am trying to reduce mouse clicks.

When picking circle I always set my auto cursor to center.

Change the filter to only pick center would be my guess.

I prefer using the "Entities" method. Works great for circles. Open arcs on the other hand, not so well.

Yes - circles do have end points - 2 of them that are coincident and usually at "3:00".

I perfer Mask On Arcs.

 

Mask On Arcs - Pick the arc you want to match, Then press - All - Arcs - End Selection.

FYI...

A change has been made to Drill Point Selection for MR1.

Now when you use the Entites selection method and tag an Arc - you always get the center point, never the end points of the arc.

Sweet!

Now when I use this method I won't have to use snap to arc center.

 

Nice!!!!

yes I can pick only center in the filter I was just trying to find a way around that option. I would prefer to set my filters for what I need 90% of the time and leave them set. (fewer clicks)

 

dwsz71 , your entities method works real well for selecting my geometry but.... the tool path comes out basically reversed from how I picked it on the screen. This creates less than desirable tool path.

 

Pete , my "endpoints" are showing up at 06:00 270º relative to the top view of my part ?

 

Mike , I tried your method and had no success with it. Being that I am masked on a 5mm hole and the hole goes through the part I end up with 2 hits per hole.

 

Roger , sounds like what I need!

 

thanks! for the replies....

Agreed. I don't care for the re-ordering of my selections either. But it always finds the center of that circle and most of the time I can find a "close enough" sort pattern.

This is a change? Are you sure about that, Roger? It's not that I don't believe you, it's just that......I don't.

 

I always use "Entities" when selecting holes. I use it because I thought it automatically found the center. That way, I can be kinda careless (read quick), and as long as I select the arc, it's gonna find the center. I just find it hard to believe that of all the times I've done it, I've NEVER selected the endpoint of a circle.

I think Roger was referring to this.

Gotcha, Dave. I tried to select the end points of a circle today and I always got the center. As you pointed out, it must only work on arcs, not circles. My bad.

The Mask on Arc function is more flexible than many users are aware of. Instead of selecting "All Arcs" as Mike suggested, Window select only the arcs that you want for comparison from a Front or Side view. This will then eliminate the selection of arcs that are the same size and angle segment but at a different depth in the geometry. HTH
