There are a variety of ways to enter data in AutoCAD. Automated scripts can be written in the language of your choice, or in LISP. You can also utilize Autodesk’s extensions or packages, such as Autodesk Map 3D and Civil 3D. You can also import an XML file or excel data file to AutoCAD’s table database program.
AutoCAD is not unique in that it requires data from third-party and external sources to be added. This is a different approach to the tutorial style. We will use AutoCAD to input survey data and other data that architects and engineers do everyday.
First things first
Understanding the nature of Auto CAD and how it connects its parts is vital in understanding the lesson. AutoCAD as with all computer systems, utilizes coordinates and points. The coordinates can be further expanded through processes and functions. These data are required to display these elements on the canvas. Each sub-topic will explain the impact of this on data entry. One good general rule of thumb is that you should refer to your revit training whenever you are doing this.
Line Segments
Each line segment is composed of the coordinate map. It indicates the distance and angle of incline to the point of origin for humans. The line’s bend will be 90@ (anticlockwise) when it reaches the point at which it crosses the ground. The bend will continue for the distance specified. It is possible to write the revit length and slope of the line segment by using the syntax below:
“@” + length + ” + Northing/Easting coordinates
This example illustrates the meaning of HTML0.
@422.25
Enter this information with the LINE command, and draw a line that is followed by. The LINE command is performed using the coordinates explained above.
Curves
Curves are curved (no pun intended) therefore you need to remember the direction of the curve. It is not required for lines. If needed, you may rotate the line at its source or from another established source.
Non-tangent Curves
If the curved shapes do extend beyond the previous drawn element, you can employ a radial bearing method to start drawing.
To draw lines, utilize the Line command. After that, you can make use of the ends to form an arch. The process of creating the curve by drawing a line. Once you’ve drawn the line, invoke the ARC command. The line’s beginning point will serve as your starting point for your curve. You can decide to set the end point, or any other point as the point of departure for the curve.
Tangent Curves
The difficulty or simplicity of the tangent curvature will be contingent on how it is defined.
Conclusion
Survey data entry is about creating lines. This article will show you how to accomplish this using the LINE / ARC command. These commands are the base of all the additional functions.
