Mass edit arc start/end angles

[Thad]

Is there a way to mass edit the arc start and end angles? Certain jobs have a lot of open arcs that I need to machine as if they're closed. "Close arc" does this just fine, but then chaining is a pain becuase I can't click thru them real fast because the start angle is different on each arc. Clicking one area of one arc will climb cut, then clicking the same area on the next arc will conventional cut because of the start angles.

That's a good question Thad. If there's a solution I will surely benefit from it.

In the mean time, I just click the, "R" key and it reverses the chain.

Yeah, me too.

In chaining option > Closed Chains > turn off "Use cursor position" & use CW or CCW, Now you can pick anywhere on a circle.

Thanks Pat. I'll see how it goes, but I'd prefer to use something that won't require turning on and off every time. This method would interfere with my "normal" chaining.

Hi Thad,

 

I bet a VB Script could do this pretty easy. Have it take each open arc and create a new arc with the same diameter and a new start/end point aligned with X 0°, then delete the original arc. Maybe have a prompt that asks if you want to perform this on all arcs, or pick individual arcs from the graphics window...

 

Now you've got me thinking...

 

I could see where this would be super useful.

With X4, It has new chaining feature, It will does what you want

Look at this:

Takashi posted a link for the beta version. I have it installed and it works great and you get an option to do what you want.

 

Hope that helps,

Martin,

 

AI Utility makes it a 2 step process, if I'm following it right. First, make all start angles 0, then make all sweep angles 360. Is that what you're doing?

 

I'm a big fan of AI Utility and I completely overlooked this one.

Thad,

 

Actually, it is done in a one step process. the name of the command is: Edit arc start angle.

 

If you go to setting → customize and you select Ai Solutions in the category, it is the 4th icon from the top.

Martin,

 

It's only a one step process if you already have a closed arc. Closing the arc and getting the start angle at 0 degrees can be done by using the 2 AI Utility features, or by using MC's close arc, then the arc start angle AI Utility feature.

 

When I only have a couple arcs to do, I use Analyze, then change the arc angles there. That closes the arc AND puts the start angle where I want it in one step. That's too much work for a bunch of holes, thus the purpose of this thread.

 

AI Utility makes pretty quick work of it.

Also consider Circle Mill. With it, I do not think that start point is an issue.
