Assemblies: Look Wrong but Build Right

If you don’t know what I’m talking about, I hope I can prepare you when it happens to you.

When laying out Assemblies sometimes the overall look can wrong, some subassemblies will even include a label “Layout Mode” to let you know that when processed in a corridor will look right.

Assemblies are building blocks to build a corridor, and are NOT intended to be plotted, we have Standard Details Sheets for that. . I’ve notice this behavior in the Generic Link to Marked Point and some Medians.

Looking at a MEDIAN assembly, this one is closing the gap from Left to Right hooking to the MarkedPoint (triangle), with positive grades crowning upward.

When built in the corridor and placed in the cross section, the positive grades.

Now using the same subassembly on the other side of the median, closing the gap from Right to Left. This time we will hooked to the MarkedPoint (triangle) will cause the subassembly to flip.

Because the median subassembly had to flip to connect, the original positive grades are now inverted too.
