Perform a Mapcheck Analysis by selecting AutoCAD Civil 3D line and curve labels to determine values from label objects based on the precision of the annotation of the label object, or enter mapcheck data manually.
A mapcheck analysis is typically performed for each labeled polygon that represents a parcel, a labeled parcel object, or survey figure to ensure that errors and omissions are minimized. If error is introduced and accumulated, the coordinates of the last segment endpoint will not equal that of the point of beginning (POB) which creates the 'error of closure'.
The report is computed based on the start and end coordinates of each parcel segment, relative to the coordinates of the POB and the previous segment.
In the Survey Command Window you have the option to list mapcheck information that computes the error of closure for a figure based on the precision settings for direction and distance values which you specify in the Survey Database settings For more information, see Listing Mapcheck Information for a Figure.
In the Parcel Properties you can specify Inverse Analysis and Mapcheck Analysis. For more information, see Exporting a Parcel Inverse or Mapcheck Report.
Topics in this section
- Performing a Mapcheck Analysis
Use the Mapcheck Analysis command to perform a mapcheck that is based on the precision of the annotation of the label object.
- Manually Entering Mapcheck Data
Create a mapcheck report by manually entering data.
- Adjusting a Mapcheck Analysis
After creating a mapcheck report by manually entering data and determining that there is a reasonable error of closure, you can adjust the mapcheck to distribute the total error among the sides to precisely match the point of beginning and endpoint coordinates.
- Inserting a Mapcheck Report as Mtext
You can insert a Mapcheck report as an Mtext object in the drawing.
- Mapcheck Command Default Settings
Change the Mapcheck default command settings in the General collection on the Settings tab in Toolspace
