Land Survey Workbench Blueprint/it

Questa pagina elenca i requisiti per l'implementazione di un nuovo ambiente di lavoro utilizzabile in Agrimensura.

Rectangle selection
A new mouse mode may be required:
 * left-click on an object selects the object
 * left-click in empty space - begin selection action; click again - end selection action, add to selection set
 * CTRL - exclude from already selected set
 * press and hold middle button to pan
 * contextual menu on right click
 * wheel up/down - zoom

Layers

 * Object properties such as color, line weight, visibility, print-ability can be set on a per-object basis or may be inherited from the parent layer.
 * Each object has a parent layer / an object may be part of a layer or not.

Blocks
Blocks are objects that behave in most circumstances as a single object. The objects do not loose their individuality inside the block. Since there is a Upgrade/Downgrade, this functionality may already be present.

Dynamic attributes
Variables. Components of the block that may be changed without changing the definition of the block. Position inside the block is one such attribute. This feature will integrate well if expressed as properties.

Points
In land survey the points are usually associated with numbers, description and other characteristics. The blocks with dynamic properties should do it.

Querry tools for 2 and a half system
The planar position is usually decoupled (especially in cadastre applications) from the height. When you want to know the distance between two points you actually want to know the distance in horizontal projection. The horizontal plane is XY, with Y pointing toward north. Z points upward (positive altitude).

Rich text; Tables
General support for rich text.

Note: the information in this page is based on a shallow understanding of FreeCAD's internals. Once it deepens the requirements and implementation may be adjusted. Contributions are welcomed! --Xtnickx 11:00, 26 January 2013 (UTC)
