Chaining

[sherjatt1]

We use MasterCam 9.1 for our machining. I converted a drawing done in Inventor and when i was chaining the bottom of a filleted pocket i notice it wont let me with a message saying not a close boundry.

i remember in school we have done something to make the chaining work. can someone please help me with that. thank you in advance for helping me.

Welcome to the forum

 

I think theres probably overlapping arcs and lines ..or no trimmed correctly. Try analyze chain or use the chook "findoverlap". the chook will show you where the problem is. If that fails (both) then I would look carefully at the endpoints of all the enties in the chain to make sure there trimmed. That should help

Bottom of the pocket is basically a rectangle with rounded corners. when i tried analyze, it basically said same thing. I know i could chain top of the pocket but its annoying me that i can't do what i really want.

You should try to squash/xform project depending

on whether your using 9 or X.

Did you also trim them all together??

 

 

PEACE

There has to be a break in the chain somewhere for you to get that error so somewhere in that chain there is a break,if you fix the break then you should be able to chain the pocket on the bottom.

The first thing I do when I have a chaining problem is delete all duplicates.

If that doesn't fix it I'll change colors and chain for selection

Then you can tell exactly where the problem is

and fix it.

Since this is imported geometry, it may be silght off on z level. A couple of tenths can screw things up. Tyr anylizing a couple of entites and see if they are on the same Z level.

If not use the "squash" function to fix it.

I don't understand what you mean by this. Maybe you can "undo" it. ???

 

What version are you using?
