APWACurbs

The APWACurbs subassembly inserts links for a standard shape concrete curb-and-gutter with subbase. The curb and gutter dimensions are based on the APWA Standard Plans for Public Works Construction, 2012 edition.

You should verify that the dimensions used match your interpretation of the standard plan.

Attachment

The attachment point is at the flange point of the gutter, the back of the curb, or the face of the curb.

Input Parameters

Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

None.

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

The curb and gutter links are inserted based on the values stored within the subassembly. All dimensions are positive, non-zero values. If a non-zero subbase depth is given, the subbase layer is not inserted. The subbase layer closes to the bottom-back-of-curb.

The subassembly builds the shape for the selected curb, curb and gutter, or surface curb, with the attachment point either at (a) inside edge of the gutter (or lip), or (b) the back of the curb or (c) the flowline (or surface) of the curb or gutter.

Layout Mode Operation

In layout mode, this subassembly displays the curb-and-gutter component based on the input parameters given.
