Components and Ground Surface Tie-ins
Components are the 2D and 3D model entities that get built, quantified, and paid for. 3D Linework can define limits for {tip title="Surface Templates" content="Given a top terrain, Surface Templates provide depth and volume. For example, if you have terrain that defines the top surface of a parking lot, Applying a Surface Template to can provide the pavement layer, aggregate layer and subbase layers. These are all quantifiable volumes."}Surface Templates{/tip}, which provide spatial components, and can provide the pathways for {tip title="Linear Components" content="Linear Components are 3D components that follow a path. They typically have fixed cross sectional geometry. Extruded curbs and gutters are excellent examples."}Linear Templates{/tip}.
Ground Surface Tie-ins can be as simple as a single cut or fill slope from along a proposed 3D linear element to the ground. Or they can be wildly complex. OpenRoads Templates are not just for corridors. They essentially "extrude" lines and shapes along any 3D element. Additionally, End Condition technology allows complex If-Then logic to model virtually any defined slope treatment standard.

Linear Components, such as curbs, and end treatments can be modeled in separate steps - individual Linear Templates - or at once using a combined Linear Template. Curb islands for vegetation within a parking lot would typically be modeled with a Curb-only Linear Template. Perimeter curbs would typically be run with a Curb-and-sideslope Linear Template.
