X Y is backwards when importing STL file

Postby xoneeleven » Fri May 06, 2016 12:02 am

Hello All,
We have an STL file created in Autocad 360

The model looks like it should, and it was exported as an STL.

We imported the STL into MeshCam Pro.

The issue is that the x/Y planes are backwards.

The actual model looks right on the screen.

However, when imported in, the dimensions load in as X=4.25in, Y=1in, Z=4.25in
Notice that the Y is what Z should be, and Z is what Y should be.
When we look at the model on the stock, it appears to be perpendicular to the stock, and not in line with it correctly.
When we setup the stock with the "correct" dimensions, the toolpath does not calculate correctly.

Has anyone else seen this type of issue?

Oh yeah. In SolidWorks, X-Y is in the plane of the screen and Z is out of the screen. In other words, X-Z is the horizontal plane. When geometry looks upright in SolidWorks, it comes in sideways in MeshCAM

That sounds exactly like what you are seeing in Autocad 360. The easy thing to do is use MeshCAM's Geometry | Rotate Geometry and click on the schematic cube where the face that should be up is highlighted red.

In SolidWorks I can define an export coordinate system, that lines up with my desired geometry orientation to use when saving the STL. Autocad 360 might have that capability too.

Thanks Randy,
I will make an attempt to follow your instructions.
Hopefully I can fumble through it with success.
