Primary/ref plane order?

Regardless of what they are named, is the first reference plane in the feature tree always the ‘front’ plane and the last the ‘right’ plane? I have found claims that suggest that there are situations where the ref plane order might be different, but I find it hard to believe that SolidWorks wouldn’t enforce a convention and render the feature tree in a consistent matter, regardless of the origin of the 3D geometry.

I renamed them Plane 1/2/3 in our templates. The idea of Front, Right and Top are meaningless for what we design.

Interesting. What are you designing?

In regards to the original question, do you know if the plane normals (x-y, y-z, z-x), regardless of what you would name them, always appear in the feature tree in the same order? It has been suggested that if you bring in a file of an older vintage or import a file from outside SolidWorks, they might have a different order.

Specialty welding equipment that our crews use to perform repairs in nuclear power plants, refineries, chemical plants, pulp and paper mills, etc. Pipes, pressure vessels and such can be horizontal, vertical, angled etc. Some times the equipment is mounted facing one way, some times the other depending on clearances. So front/back, top/bottom, left/right are meaningless.

I’ve been using SOLIDWORKS since 1997 and I do not recall any other order of the primary planes or orientation of the plane normals. I regularly open models created back then with newer SW versions and everything looks the same.
