Base Map Control

Overview

ASE Civil's Base Map Control system is unique to the application. 'BMC' records the horizontal characteristics of the project site layout or 'base file' drawing. ASE takes a 'snapshot' of particular layers of your 2-dimensional linework, such as centerlines, rights-of-way, curbs, sidewalks, etc.

 

'Virtual' Offset Alignments

As a direct result of the 'BMC' subsystem, ASE Civil can easily apply vertical design data through these corridor regions:

  • Knuckles

  • Cul-de-sacs

    • Offset

    • Symmetric

    • Pure curve geometry (no linear connectors between returns and turnaround bulb)

    • With linear connecting geometry (either or both sides)

    • With or without islands

  • Curb widenings

  • Medians

  • Half-streets

  • and more...

 

Since ASE Civil can automatically identify the critical elements of a wide variety of corridor configurations, the is no reason to define any additional offset alignments.

Requirements

The following items are required for creating Base Map Control data:

 

Source Drawing

A project site layout or base map drawing should be available. The source drawing must contain all of the required site layout 'key elements':

  • Property lines

  • Rights-of-Way

  • Centerlines

  • Crowns

  • Curbs

  • Edges of Pavement

  • Boundary

 

Layer Organization

Key elements of the source drawing should be organized and separated onto their individual representative layers. Logical layer naming practices are highly recommended, but are not a functional requirement by ASE.

Geometric Integrity

All 'key elements' must be 2-D geometry.

Source geometry must be unreferenced, existing locally within the source drawing.

The drawing geometry should be tangent and mathematically accurate.

Avoid overlaid / duplicated objects.

ASE Data Folder

An ASE project data folder must exist and the source drawing must be connected to it.

 

Definition

Base Map Control data can be defined directly from the project site layout or 'base file' drawing. ASE records geometric properties of all arcs and lines on the key-layers within the site layout drawing.

 

Procedure

 

  • Open the site layout or source drawing from which the data will be defined

  • Check or set the ASE Project Data Path

  • (Menu) Select: [mgt] → Base Map Ctl → Create...

  • In the definition dialog, verify layer names found for the corresponding "Control Systems"

  • Make any needed adjustments to the interpreted layers [2]

  • Click 'OK' to close the dialog [3]

  • Read the 'Information' dialog and choose to SAVE the drawing with all POLYLINES exploded or EXIT [1]

  • Press 'OK' to close the 'Information' dialog

Notes

[1] Your decision to SAVE or QUIT without saving will have no effect on BMC data that has been created. Data is written immediately after layer verification

[2] If a system will not be used in BMC definition, select an empty layer or a layer that does not contain LINEs, ARCs or POLYLINEs

[3] At this stage, BMC data has now been recorded in the ASE Project Data Folder
