Backing Sheet

DRAW Administrator Guide

Isometric Automatic Drawing Production : Configuration : Backing Sheet

The Backing Sheet contains the border lines and hash codes for areas on the drawing such as the Title Block and the Revision History Block.

These areas can be repositioned anywhere on the drawing. The Backing Sheet contains data that determines where the drawing elements are located and the space available for them.

IsoADP designates Reserved Areas by providing a series of RECT elements, one for each reserved area. Each rectangle element has a UDA (:IdpFunc) that is set to a word that describes its function, to differentiate it from any others on the drawings and hence it is mandatory that this attribute is set.

A pictorial representation of the supplied Reserved Areas is:

For example, the supplied metric A3 backing sheet, has the following Reserved Areas all of which are located in a single NOTE:

The NOTE element has its attribute LVIS set to FALSE so that the reserved areas do not display on the drawing. In order to view and modify them, set the NOTE attribute LVIS to TRUE.

Note:

Reset the Layer Visibility to False afterwards.

Each Reserved Area RECTANGLE element has the User-defined Attribute :IdpFunc, which is set to a word that describes its use:


View	The Main Isometric View.
Mto	The Material take-off table.
Location	The Location View that displays the Sheet section of an HVAC or PIPE relative to the whole HVAC or PIPE.
KeyPlan	The Key plan displaying the position of the Sheet section of HVAC or PIPE relative to the reference grid.
NorthArrow	The North Direction Arrow.
Revision	The first area for the Revision History. It is important that the rectangles are held in the same order in the hierarchy as they are to be filled with history data. The first in the list order is filled first, followed by the second and continues as required.
Revision	The second area for the Revision History, acts as the overflow from the first Revision History area.

Note:

It is important that the words described are used and not any others, as the code only looks for these.

Note:

Each rectangle must have its origin set as Centre. The code then calculates the relevant corner data using that position and the rectangle size.
