Grid Lines on multiple stories

Here are the notes I wrote to myself when I was last trying to puzzle out how the grid tool works.....

 

Put grid line objects on dedicated “grid” layer

Put them in class “none” (to make sure they’ll appear in all viewport annotations)

Grid line objects can be styled.

Grid line style has design layer grid line instances called “grid line definitions” (drawn on “grid” layer). Each design layer grid line definition has its own letter/number (label)

Each definition has a real-world start and end point. 

Then each of those has multiple instances in viewport annotation spaces

Changing “show bubble at” in a definition doesn’t change already-drawn VP instances

Changing “shoulder length” in a definition does change already-drawn VP instances

Changing start & end points in a definition does change already-drawn VP instances

Changing “bubble scale factor” in a definition does change already-drawn VP instances

To avoid confusion, when drawing grid line definitions in the grid layer, leave shoulder length and bubble scale as per style.

Changing attributes in VP instances only applies to that VP instance.

[for now] attributes of grid line “lines” and “shoulders” set within style and not by class, and take on class of object (none)

A kind of default “Shoulder length at” and “show bubble at” can be set within grid line style, and will apply to any newly drawn definition, but can be overridden in any definition and in any VP instance (in the OIP)

Grid lines should appear in any viewport:

– where GRID layer and none class are visible

- where they are perpendicular to the VP view direction

- where they are within (or intersect with) the VP’s crop

- where, in the grid line definition’s OIP, under “grid line instances”, the relevant viewport has a tick against it. NB therefore grid line visibility in viewports is controlled by the definition’s OIP, not within the viewports’ OIP.

A GL instance’s start & end in a VP are determined by the crop box (unless real world start/ends as drawn on Grid layer are inside the crop box. But can then be overridden manually. Manual adjustment will be remembered if crop box subsequently changed.
