Chains reversing when using chain feature option

Re: X7

Chamfering bores, see example

 

I've never had this problem before. The upper left hand circle shows the arrow in the direction I want to chamfer these holes. Notice the direction of the arrow for the additional chains is in the wrong direction causing the cutter to comp to the wrong side of the chain. I  used chain feature to select the additional circles and no matter what I do outside of reversing each chain individually it won't correct this. Any suggestions? Could it be the model? I did notice my edge curves for these holes are (2) 180 degree arcs but it chains the entire arc as one chain.

I notice you have the solid level open at the same time as the wireframe. Do you have overlapping entities by chance? I would have just my one level on with the chamfer circles and make sure that is the only thing you are working with.

[tiredtoolmaker]

I turned off all but the wireframe and I still get the same thing. When I analyze each circle, it is made up of two arcs, one is 0-180 deg and the other 180-360.

I believe its quicker to reverse each chain than to close all these arcs.

[tiredtoolmaker]

I closed two of the arcs and it chained both in same direction. Not exactly what I'm after though.

not really a big deal just reverse the chain

If I remember correctly, there was a directional chaining issue with the older versions that has since been corrected

For what it's worth,

 

When you have a solid like that, sometimes as you've seen, it will create "weird" geometry.

 

If you are using X9, then try using the "Hole Axis" (under Model Prep). With this "Hole Axis" function, you can create Centerlines for the center of the bore. But, you can also use the function to generate Circles at the Top and/or Bottom of the hole.

 

You can use this function to generate new Circles, and they should generate as a "Clean" Arc. You can choose to do it on Top or Bottom of all the holes, and do it all in one shot.

This is the small plate. On the big plate, I can reverse 175 chains to climb mill or reverse my initial chain and conventional cut all 176. it won't get away from conventional on chain feature.

Using X7

Using X7

 

X7 is an older version

[tiredtoolmaker]

  There might be a better way but I got it. I selected my first circle as conventional milling then selected chain feature. Now all chains show conventional. then I right clicked on the red arrow under chain manager and selected change side and it gave me what I wanted.

 

Is there a way to quick mask chains and reverse all?

 

 

 

  Thanks for the suggestions.

Even better, i saved the model as a step file and it solved my problem. No divided curves anymore.
