Autocad Lisp For Area

Function Syntax A2F Current Version 1.3 Download View HTML Version Donate Program Description This program allows a user to create an MText object containing a Field Expression referencing the area, or sum of areas, of one or more selected objects. Upon issuing the command syntax A2F at the AutoCAD command-line, the user is prompted to make a selection of objects for which to retrieve the area; if more than one object is selected, the cumulative area for all objects will be displayed by the resultant MText Field. Following object selection, the user is prompted to pick a point at which to create the MText Field.

If the specified point resides within an AutoCAD table cell, the program will populate the table cell with the appropriate Field Expression. The Field will display the sum of the areas of the selected objects, formatted using the Field formatting code specified at the top of the program - this formatting code may be altered to suit the user's requirements and is described in more detail below. • Type FIELD at the AutoCAD command-line and press ENTER to open the Field dialog. • Select Objects from the 'Field Category' drop-down menu. • Select Object from the 'Field Names' section.

The area of the object will appear above command line along with its perimeter or circumference. In a similar way, you can find the area of any closed Polyline geometry with AREA command. Watch this video for a detailed tutorial on Area command and other tools related to finding different geometrical properties of an object in AutoCAD.

• Select an object (with area) from the drawing by clicking the object selection button adjacent to the 'Object Type' box. • Select the Area property from the 'Property' panel. • Configure the formatting options as desired. • Click OK and pick a point in the drawing to create a temporary MText Field.

• Download & load my program. • Type fieldformat to run the program and select the temporary MText Field created earlier. • Following a valid selection, the field formatting code will be printed to the command-line, e.g.

In this article I will explain three different methods of finding areas with AutoCAD, I will use the geometry shown in the image below for explaining this tip. AREA command: In order to find the area of rectangle or circle from the image above type AREA on the command line and press enter. Now command line will show a prompt with many options as shown in the image below. Select Object from this prompt and click on the boundary of Rectangle or Circle for which you want to find the area.

The area of the object will appear above command line along with its perimeter or circumference. In a similar way, you can find the area of any closed Polyline geometry with AREA command. Watch this video for a detailed tutorial on Area command and other tools related to finding different geometrical properties of an object in AutoCAD. Using hatch: You can use hatch command also to find the area of enclosed geometries. In the example drawing shown above area B (indicated by blue color) is enclosed by circle and rectangle and you can make a hatch in that area and find the area of that region using area of the hatch.

Create a hatch in region B of sample drawing, you can use any hatch pattern for this. Now exit hatch command and select hatch created in area B then right click and select properties from the contextual menu. A property palette will appear, scroll down in the palette and locate geometries panel there you will see Area of the hatch. This hatch area will also be the area of enclosed geometry. Using JOIN command: Let’s take the example of figure D from sample drawing shown above. In this case, we have a geometry made up of Spline, Line and Arc. You can’t use AREA command on this geometry because we don’t have a single object here so I will use JOIN command for finding its area.

Type J on the command line and press enter now select complete geometry and press enter again, this will join complete geometry into a single unit. Now select geometry then right-click and go to properties from the contextual menu, scroll down in this menu and here too you will the see area and total boundary length of the closed geometry. Instead of using JOIN command you can also use REGION for combining geometries into a single unit and then find its area from properties palette.
