Cant join entities in X

[Thinwater]

I have a part that I drew with Mastercam X. It is a 42mm square with 23.750 mm radiused corners. I drew it by making the box, then overlapping a 47mm circle. I cut away the extra peices and am left with the correct shape. I cant get a tool path because the parts are not joined. The software wont let me join them. I re drew it and tried to join them then they are both still one peice but that wont work either. I am reading my mastercam mill training book now trying to find this.

This shape is to simple to have this much trouble with. I know it is just me not knowing what to do but this should not be that hard. This software should join anything I tell it to join. Its cut/trim features and joining are a pain.

Any ideas?

If you dynamically rotate your geometry on the screen you may find that the entities do not actually intersect in 3-d space. I am imagining you are only using the "top" view but when you dynamically rotate you may be able to see the gaps if they are large enough...

If you can't get it figured out just click on Help, Create Zip to Go....

Then look in your "my Documents" folder for the .z2g file and post it up here and I'll figure it out for you.

Providing that all the entities are in the same Z plane, which you can analyze each entity to make sure.

I am not sure how you drew your radii by your description, but if it's just a corner radius, fillet works best, automatically trimming the entities together.

If by another means, you can trim 2 entities together. By selecting each entity, the line and arc, they will extend together.

Join itself is a different function which join two similar entities to one entity, example, 2 separate lines with the same vector. Join creates one entity out of each.

I think you just want both entities trimmed to form a "Closed" chain.

A couple of reasons why you may not chain is
-duplicate entities
-branches
-chaining method not selected ( read the prompts under your main toolbars )
-gaps

start by deleting duplicate entities, everyone has problems not noticing entities on top of one another

Do what Superman said. If that does not solve the problem try this. Select all the entities then go to the Xform pulldown menu and select Project, this will allow you to project everything flat to a plane (or several other ways of achieving desired results).

DO you relize that you can create a reactangle option and at the same time have it create the fillets at the same time.

Also you wanted to use the option of "Create" "Fillet" "enitites" the default will Trim.

Thanks all, I re-drew it and it worked. I think I had a duplicate line or two.

This is a great site!

I have never noticed that. I am gonna look at that next time I have to draw something up.

Good tip cadcam!
