This 26 minute lesson shows how to draft the property lines based on a survey document, either on paper or as a PDF. The use of metes and bounds with survey bearings (degrees, minutes and seconds based on the North orientation) is demonstrated.
A new independent worksheet is created for drafting the property lines. The Options menu > Project Preferences > Working Units command is used so that model distances may be entered and viewed as decimal feet or meters, with angle measurements in surveyor’s units.
Property lines may then be easily entered using the Tracker. Type in the distance first, then hit Tab and enter the bearing angle with “s” or “n” followed by the number of degrees, a “space” to separate, then the number minutes, another space then the number of seconds, and finally an “e” or “w” before hitting Enter to conclude the input.
IMPORTANT NOTE: To work properly with survey bearing angles, make sure that the Options menu > Work Environment > Tracker and Coordinate Input checkboxes for “Use relative angle measures” and “Use angle relative to the active Guide Line” are NOT checked. In ArchiCAD 15, this is automatically turned off by ArchiCAD whenever surveyor’s units are chosen; in ArchiCAD 14 and earlier, this must be done manually by the user.
Follow the sequence of lines around the outside boundary and test that it closes properly. When creating a curved segment, create the chord or straight segment, then curve that line to the proper radius. In earlier versions of ArchiCAD, the Tracker may not give useful feedback for the radius of this curve, so follow the steps outlined in the video to create an arc or circle of proper radius then later move it into position.
When creating dimensions for the property boundary lines, set the Dimension Preferences to give the desired units, and adjust the Scale as needed, then make sure to record these in the View Settings.
A shortcut is shown to create the text representing the bearing angle in survey units: use the Measure tool along the property line, hit “a” to highlight the angle measurement, and copy it. After canceling out of the Measure tool using the Escape key, start to place a text block by double-clicking with the Text tool, then paste in the bearing data that was copied from the Measure tool.
