Layer and Surface Standards

For years now, Quantum Land Design has used a standard layer and surface naming convention for all of our machine control models.


We use plain language and simple abbreviations to make our standards easy to understand and use in the field. The picture below spells it all out, click on it to view full screen or scroll down to read the details.

Machine Control Model Standards

Lines (linework, polylines)

2D Lines

Labeled in plain English.

Layers added as necessary per project.

All lines are 2D unless noted.

3D Lines

Always have “-3D” prefix

Examples: "-3D-Storm" or "-3D-Centerline"

Projects with 2D and 3D lines will always have both line types.

Projects with 3D utility model surfaces will always have a corresponding 3D line.

Revisions

Lines changes during revisions will be appended with the date of the revision.

Example : "-3D-Storm-3-8-22"


Surfaces

Standard Abbreviations

FG = Finish Grade

SG = Sub Grade

SAN = Sanitary Sewer

STM = Storm Sewer

WTR = Water Line


Additional 3D surfaces for structural features, underground detention systems, etc… will be named as appropriate.

Revisions

Surfaces changed during revisions will be appended with the date of the revision.

Example: "FG-3-8-22" or "STM-12-14-21"
