Arr

Command line: arr

Description: calculate, record and create table for one area

TopoLT toolbar:

Menu: TopoLT » Areas » Calculate and record

Area’s calculation can be done over a polyline or circle. Circle can be determined by three points, two diametrical opposed points or by center point and radius. Polylines can contain arcs too but compulsory must have a point on arc, if not, this will be introduced automatically.

When applying this command, in case one or more points that define object are missing for selected object, new points will be introduced. Numbering new introduced points will be accordingly to the last point graphically introduced.

Selected object, polyline or circle will be corrected by fixing points to decimals, accordingly to decimals’ number allocated in section Points. Therefore, both polyline’s margins and vertex in arc of polyline will be slightly moved to pass through point. This slight move is available for circles too, by slightly changing the radius and center's position.

For calculated areas, you can create table with area’s calculation both in an external file arr.rtf and inside drawing.

To describe area the following data will be necessary: parcel’s number, parcel’s destination, parcel’s type and in case type is number 1, it is considered this is a construction and program will demand levels number and construction characteristics.

For construction type (1, 2, 3…) you can make the association between number and layer that is defined in layers’ file where is allocation ARR. For example, for orderly allocations made in layers’ file ARR - Constructions, ARR - Transport, ARR - Networks, ARR - Free, when you calculate an area of type 2 this area will be passed on layer Transport.

In case you want each calculated parcel to be passed on a layer, it is recommended to introduce new layers allocated for command Arr in layers’ file.

An area’s labels can be inserted or not in drawing, area can be hatched or not. Hatch will be accordingly to the last hatching made in drawing, rotated with 110g.
