SECAREA SOFTWARE IN AUTOCAD ENVIRONMENT

THIS IS USER'S MANUAL FOR CADMAX'S SECAREA PROGRAM, WHICH WILL BE
USEFUL FOR PLOTTING LEVELS OF CROSS SECTIONS AND CALCULATING
CUTTING AND FILLING AREAS AND VOLUMES.

DOWNLOAD FROM FOLLOWING LINK
http://www.nirt.in/software/secarea.zip

Installation of AutoCAD 2000 or higher version software had to be preloaded in your computer for loading this SECAREA SOFTWARE with VBA enabled and follow the steps listed below:

STEP.1.
    Unzip the SECAREA SOFTWARE downloaded.
STEP.2.
    Using windows explorer copy all the unzipped files in a folder C:\SECAREA.
STEP.3.
    Now Select all the files in the folder using windows explorer and check for properties of files and if they are read-only files uncheck read only option.
STEP.4.
    Then close the windows explorer.
STEP.5.
    Right-click on the existing AutoCAD icon and then click on the “create shortcut” option to create a new AutoCAD icon.

STEP.6.
    Right-click on the new AutoCAD icon and then click on the “Rename” option to rename the icon as SECAREA icon.

STEP.7.
    Right-click on the new SECAREA icon and then click on the “Properties” option to set the new properties. In the properties dialog box change the Start in folder as “C:\SECAREA” that is where the software is copied and then apply and close the properties dialog box.

STEP.8.
    Double click on the new  SECAREA  icon  to start AutoCAD .

STEP.9.
           Click the Tools menu and then click Customise menus to load the SECAREA.MNC file in the C:\SECAREA folder and insert the CADMAX pop-up menu before Help menu. For AutoCAD 2007 or higher version CADMAX.CUIX file HAS TO BE CREATED FROM CADMAX.MNU FILE AND LOADED IN THE MENU.

Now the SECAREA software is loaded and ready to run through pop-up menu or equivalent commands at the command prompt.

   nil
   (Now you will see the Forlevels at regular intervals)

18.AT THE COMMAND PROMPT GIVE "LVLTYP" COMMAND TO INITIATE/CHANGE
