chaning in mastercam

[ghostlx]

hello to all
I have a question about chaning contours in mastercam.
I am working on a project in mastercam art to carve a plack for over my fire place.
the problem is 1 of the letters is broken in to ,little segments and will not completly chain how can i join them together ?
ihave tried to translate and join but i am missing some thing
thanks

Have you tried delete duplicate entities. Select all the delete. Some times there are lines over lines that confuse the chain. Also analyze is a good diagnostic tool.

You could also reduce the tolerance in the chaining options if it's for art.

thanks john will have to read up on this I had to erase all double lines and eaven draw some of them over to make it work. ya know its funny in autocad I could convert all the lines to polly lines and eaven close them. but somtimes mastercam will leave them open and broken .
but thank you for the help

I seem to remember that:-
Mastercam does not like polylines, ( at all ), it cam import them but will not give them to you as splines, they come in as automatically segmented lines which are not trimmed, which make it a real b1tch to chain.

The only suggestion could make, is to open the chaining tolerance and offset the contour (round corners = none ), delete the original and offset it back to the correct position.

sounds intersting I will try this on my next project
thanks for the tip

@jeff..How much are your post and what payment method do you accept??

After youve done the Delete Duplicates.

Use Analyze Distance to determine the gap size.

On the chaining dialog, at the bottom, there's an Options button. Find the chaining tolerance (usually .0001). Set it to just over the gap size.

It's not really a substitute for good geometry, but it will get you thru the day.

Thanks mike that by far sounds easer than zooming in and playing connect the dots
thanks

hey mike
would you help me out ?
i'm working on a project for a christmass present for a instructor at work.
I create a art base surface and when i start to chain the object i get segmented lines and its being a real pain tried to use the analise feature that you discussed and i cannot see a gap distance i expanded the chain distance to .025 but that did not help . it just might be a bad drawing also. but could i send you a dfx of what i am doing . and get you to take a look at it and maybe offer a solution as what to do.
thanks for your time

Try this. New Level and New Color.

Now Create - Spline
and pick point on top of what you have.
Dont try to do it all with 1 big spline. End/Create new splines at the sharp intersections.

The turn off your old geometry and just machine the new splines.
