Create an outer boundary and an inner boundary. Outer boundary should be self explanatory and the inner boundary will be the area that you want to avoid.

It takes some playing with to get your spacing right, but in the Create Letters dialog box, check Top of Chain, then select the bottom arc when prompted.

Our designers use Logopress (plugin/addon, whatever it's called) with SW when designing dies. I'm not sure if figuring overbend is part of what it does, but we use it for designing prog dies.

Here's your problem. Check None instead of Lines.

They are really points. I can highlight them, delete them whatever. It's just a pain when there are lots of them confusing a drawing. 

I have unselected the "display arc center points" box in setting/configuration/CAD settings but they still keep coming back.  See attached screenshot

I certainly understand what a pain that would be. If they are points, which you say they are, then the display arc center points config setting won't do anything for you. Actual points are displayed differently than arc center points. See below. The one on the right is a point. Inside the circle is an arc center point.

You could also use the keyboard to lock the selection ... Only drawback is you have to press the key each time before a selection.

Then it's not locking the selection.

I meant that I don't understand how to lock the autocursor, to any selection type.

In X9, you right click on the autocursor selection.

I use X9 and I don't see this behavior when creating fillets or otherwise. Are you sure they're actual points? Click Screen-->Statistics. Does it list a certain number of points? If not, then they appear to be a graphical glitch. Try Screen-->Regenerate display list and see if that makes them disappear. If it does, then it's possibly a video card/display issue.

I've seen this before myself. Regenerate display list always fixed it. I'm still using X9, so it's probably in the same place as X7 -->Screen-Regenerate display list.

i dont know if its the simplest way but it works .

It doesn't sound like the simplest way to me. Try the method I (with the help of JP) mentioned above. 

Create point position-Autocursor Relative-click your corner- type in your XY position.

Don't forget that Mastercam still supports the Autocad method of inputting X, Y and Z locations. To keep it simple, pick the point tool. Now, just start typing. 0,0,0 will put a point at X0-Y0 and Z0. Typing .5,1.5,2.0 will put a point at that location. Don't forget the commas. This also works for any and every position input.

In this case, he wants to add points a specified distance off of non-zero edges.

hitting space bar after clicking the anchor point maybe

JP called it.

Prior to the X series of MC, there used to be a Relative option. So you could use Create Point Relative, click your corner, then type your incremental XY location. Not sure what happened to that with the interface change.

@kunfuzed  The real question is....do you still have the milk jug?

They thought it would take 20 hours. Just finished up 550 parts in 10.5 hours.    

Thanks again for all of your input.

The helical circle mill would helical bore thru the hole at a smaller diameter then give a finish circle pass to remove the burr.

I'm doing that with an 1/8 coated OSG end mill and it's almost burr free. 

You guys RAWK! 

We're adding the white hole and we're making due with the check fixture as our holding fixture (clamps not shown).

From the front. See the gap below?

That's 6" from the top of the green plate to the surface where the new hole is going.

Need quick turnaroud, no real time to order more tooling, etc. We'll have someone run a chamfer on then on the drill press if we have to. We just need to get them done and out the door.

Would the part flexing during drilling cause a larger burr? There is no support underneath the part. The part is quite rigid (has a strengthening bead) but it does flex a bit under pressure.

Just now, gcode said:

yank should be able to help you with that 

I'll just punch the burr right in the face.

Does anyone have any advice on controlling the burr? The exit burr is quite heavy.

Edited to say that I'm running at 100 SFM and .002 per tooth. (1486 RPM and 3 IPM).

Thanky you all. You guys are great! 

Can anyone offer some speed/feed recommendations for plain old uncoated, 2 flute, solid carbide, Hertel, 118 degree drill? I found a Hertel chart that says 80-300 SFM and .005 per tooth for a material type of "Stainless Steel (soft)." I'm not sure where 316 stainless falls in the Stainless Steel (soft) realm. Any advice is appreciated.

Thank you all for the help. The tooling order has been placed. Certainly not a well planned out situation, but that's how we roll here.

Why isn't 3 flute an option?

MSC carries SGS & they make a very good 3 flute drill.

Got a link? I don't see 3 flute drills there.

Yes. IT is a sheet metal part how tight you need to hold the true position on it? that thin no reason to spot in my mind especially with a 3 flute drill. 

Three flute drill doesn't look an option for us. Also, we're limited to what's offered at MSC.

My concern with whether to spot or not was because of the carbide drill, not the part thickness. Isn't there an issue of blown corners on a carbide drill when spotting the hole first? I'm kinda new to the carbide drill thing and production is not my forte. Oh...and hurry up, Thad.
