Graphical Pre-planning

The pre-planning can also be created graphically on pages of the "Pre-planning" page type. To this purpose a segment can be represented graphically by a box, a polygon or an open polyline. In the graphical pre-planning, there are no connection points and logical connections.

Structure segments are drawn on a pre-planning page like structure boxes, and planning objects like black boxes. But the symbols used differ.

Connection planning objects (piping planning objects and cable planning objects) are represented graphically by an open polyline. The source and target segment of a connection planning object are specified by placing start and end points of the polyline on the desired segments.

Determination of the structure

The page structure does not affect the graphically placed segments.

When drawing new segments as boxes the structure is determined from the graphical arrangement of the segments. When placing existing segments out of the pre-planning navigator the structure is retained in most cases. The exceptions are:

  • A segment is placed within the graphic of a box whose segment belongs to a different structure.
  • The box of a segment is moved within the graphic into the box of a different segment.

When new segments are inserted, an outer box always becomes the top node within the structure of the pre-planning navigator. By nesting further boxes within this superior box, subordinate segments are created.

When placing existing segments, the graphical pre-planning can begin with any node in the structure.

In the pre-planning navigator, there may be further (non-graphical) segments below the graphically planned segments.

Multiple placement

A segment can be placed graphically multiple times (out of the pre-planning navigator). This means it is possible to display a segment on multiple pre-planning pages.

Only the first placement of a structure segment or planning object may be located within a box in the graphic. Further placements cannot be carried out within a different box. In such a case you receive a corresponding message from the program.

Editing of segments

When segments are placed on a pre-planning page, they cannot be moved in the pre-planning navigator.

When graphically placed segments are deleted, the subordinate segments are not deleted. Only if all subordinate segments are unplaced does a prompt appear whether they are to be deleted as well.

Tip:

Placed segments can be stored in window or page macros. This way, the graphical pre-planning can be created also by means of macros.
