Portion of a General Plan Data Sheet, showing the Block Data, Co-ordinates and Areas


  The GP Data Sheet CAD Application


This CAD application incorporates specific functions for the creation of GP Data Sheets. The format of the Sheets created conforms with the requirements of the Surveyors General in all provinces of South Africa, in Namibia, Swaziland, Lesotho, Zimbabwe, Malawi and Zambia.

A GP Data Sheet extracts its necessary information from any, or all, of the existing General Plan Sheets, related to the current Co-ordinate File.

Up to 10 Data Sheets may be created for any Co-ordinate File. For large developments, for example, one Data Sheet may be used for the Co-ordinates and another for the Areas.

For small developments, the Data Sheet information may be transferred to a General Plan, so that all plan and tabular data can be displayed on a single sheet.

Once User defined options have been set, the application will automatically generate the tables of Co-ordinates and/or Areas, extracted from the General Plan Sheets.

After generation of the table(s), CAD functions exist for User modification of any displayed Line or Text Items.

A variety of Text related functions may be employed for completing, or modifying the headings, etc.

Using simple mouse or keyboard commands, the on-screen view of a Data Sheet may be :-

Zoomed Up,

Zoomed Down,

Zoomed to a defined window,

Zoomed to the defined Plotting scale,

Zoomed to a User defined scale,

Rotated positively or negatively,
