STL file in wrong location

[Jason B.]

Every time I create an STL file in my CAD software and bring it in to MX3 it is not in the proper position. I had an A-plate that was just a square block with 4 square inserts in it with XYZ zero being in the center of the plate. When I bring it in to Mastercam for use in verify, it always goes to .250 off the far lower left corner for X and Y zero. It is correctly postitioned in my Cad system and 3D is turned on when outputting. Anyone else having this problem or know what might be causing it? I have looked through the options for exporting and importing but don't see anything wrong.

 

Thanks,

I had the same problem. Check in the operations manager then the stock setup. The "Stock View" affects your stl location. Should probably be set to TOP. I believe another member (Colin) wrote up a post on this topic. You might want to search for that.

Thanks Jrygus. I did look for "STL wrong position" or something like that, but didn't come up with anything. I will try your suggestion next.

To give you a point in the right direction.

 

Have a look at your "System Config" under "convertors".

 

There is a section about how exported STL files are handled regarding the origin.

-you can select :- local or World

 

Jrygus suggests going back to TOP, which is the same as having World as the default

you can also use the X-form STL to re-position the part in your mcam file

[gcode]

Depending on which cad system you are using

you can export STL and solid models in any orientation you like. SolidWorks has a feature called Co-ordinante system that is like Mastercam's WCS.. You can create them and aplly them to models when you eport them.

When you bring them into Mastercam they land the way you defined them in SolidWorks

OK. Figured it out. It was indeed my CAD software not Mastercam. It has an option to "transform vertices into the positive quadrant" Which was checked on. I need it to do this for the files that I send to the prototypers and didn't really realize what it was doing to my file until just now.

 

Thanks for the replys and help guys.
