Creating an Overlay Sheet and its Content

To create and display a new OVER, proceed as follows:

1. Navigate to the appropriate SHLB level.

2. Select Create > Overlay Sheet.

   It is recommended that you give the new OVER a name to make its content obvious to users. This is important; as each drawing sheet is likely to reference several overlay sheets simultaneously. The function of the Ruleset Reference drop-down list will be explained in Step 4.

   In its simplest form, the OVER is a drawing sheet on which you can position NOTEs, for which the procedure is exactly the same as for a BACK (see Creating a Backing Sheet and its Content). However, an OVER can also own VIEWs, (typically used to display keyplan views of all or part of the Design DB), each of which can own one or more LAYERs, each of which can, in turn, own VNOTEs (View Notes). It is the VIEWs, and their members, which we will consider further (see Database Hierarchy).

   Hint: You will find it easier to position and align individual VIEWs and their members if you display a working grid with a fairly small spacing (say 10 mm) and set the snap function to on.

3. To create a VIEW in an OVER, select Create > View > Limits Defined or Create > View > User Defined and set the VIEW attributes.

   Each VIEW can reference a Ruleset which defines the way in which its Design graphics are to be drawn.

4. You can set the Ruleset Reference either at individual VIEW level, or at OVER level (see Step 2), or at SHLB level (Creating a Sheet Library).

   Note: When you create a VIEW, a set of LAYERs is created automatically, their function and content being determined by the default settings, as explained in Layer Purpose Definitions. (This is exactly the same as for the creation of VIEWs during the normal use of Draft.)

5. To create a VNOTE, navigate to the appropriate LAYER level and select Create > Note > Over.

   Depending on the detailed design required, create one or more features of the View Note using the Draw options on the main menu. As you create each feature, use the cursor to position it and, for a primitive, to define its size. If the grid‑snap function prevents you setting the precise position or size that you want, either turn snapping off temporarily or modify the attributes of the primitive later.
