problem with join entities

[cob]

some times when I am trying to do a toolpath like say facing . I pick the chain to go around a square and it does not cain all around.
then I try to join them together with the (join entities) function but it does not let me join them
how else can I join them together.

when you are not able to chain completely what message does mastercam give you? are you getting a message about break points? are you using 2D or 3D chaining? sometimes you have to use partial chain or single chain to get what you want. often I change the type of chaining as i go along depending on the geometry. i do not see why you would need to use join entities. also check out analyze chain which can help you figure out if your geometry has problems.

If you cannot Join 2 entities, you have one of 3 problems: At least one of the entities is a NURBS spline, the two entities do not intersect, the 2 entities are not on the same plane (also not intersecting).

you may also have duplicates, use delete duplicates.

you should be looking at trimming the enitis together instead of join. also are there other enities standing vertical for example at the branch points of the enitis you ae picking?

sorry. branch points not break points. my bad.

Try when doing the chainning to cahnge from 3d cahinning to C-plain this will help if there are standing eneitys in a diffrent plane.

Thanks for the replies got it to work.

I wounder when would someone be concider
Good at mastercam there is way to much
Stuff to learn .

keep working it and do not be afraid to ask more questions.

Lots of seat time. Lots of work around. Lots of trial and error

exactly what type of entities can be joined? two lines? or do they have to be solids/surfaces?

Lines and arcs using the Join option under edit.
