Starting with AC 10, we will use 'real' section markers.
When we started with AC 5.1, there were fixed section marker styles. (Like the fixed dimension ticks and arrowheads to this day.) We didn't like the available styles, so we adopted the policy of showing sections in plan with an object, independent of the SE cutting element. The independent object also means we can fudge the placement of the marker, rather than being bound to its actual extent. And we can have that two-headed marker option.
In 8 (I think), they instituted GDL section markers, so we can in principle make markers any way we want. In practice, scripting SE markers is rather quirky, and I decided to punt, waiting to see if it would improve.
In 10, they have
overhauled tweaked the reference method internally. It's mostly good, but the workaround linked above is actually made worse. I can't take it anymore.
And no, the scripting is still weird. In 10, SEs have visible hotspots that aren't detectable. Gimme a break. But on balance the time is now to switch to real sections.
Object Pros: Total scripting control. Flexibility in graphic placement. Cons: Awkward drawing referencing. People think we're weird.
Real SE Pros: Unity. More intuitive, not fighting the program. Automatic referencing. Cons: Less graphic flexibility.
Standards and template updates are below the fold.
