The Volume Drawing component uses a template to create drawings. You can place a view on the template and associate the view with a view style to control the output. To define the contents of the view, you create a drawing volume in the model. Before you create these types of drawings, an administrator should create or edit drawing view styles and templates for use with the drawings. For example, you can place title block labels and reports on the templates to reflect your project or company standards.
After you have your view styles and templates in place, you are ready to start creating drawings. The volume drawings require that the changes occur within the drawing template.
The software allows you to place several views on a template, each with independent scale. In the Space Management task, you can place a volume, which is associated to single or multiple views. The volume you create in Space Management is associated with all the views you create within a volume drawing template. Therefore, in a multiple view volume drawing, you can have multiple views of the same volume, and each view specifies the style, scale, and orientation for the volume associated with the view. If the volume you create is too big for a particular view at its scale, the volume is clipped.
For example, if you place two views in a drawing template with the following property settings:
DrawingView1 - Size 6" x 6", Scale 1" = 1', and Orientation = Plan
DrawingView2 - Size 6" x 6", Scale 1" = 1', and Orientation = North,
you use the Place Volume By 2-Points command in the Space Management task from coordinates (0,0,0) to (6,6,6). In this case, the volume is exactly the right size based on scale and orientation. The generated drawing contains the complete contents of the volume.
However, if your volume was placed from (0,0,0) to (8,6,6), the volume is too big for the drawing view on the template. The maximum volume size the view can accommodate is no more than 6 inches on each side. The software centers the volume in the drawing view, effectively giving you the information from (1,0,0) to <7,6,6 in the output drawing.
The overall processing for volume drawings is as follows:
Identify a drawing volume. This is a query of all the objects that have been created in the database which reside inside the volume borders. The objects do not have to be visible or even in the current workspace to be included.
When the drawing is created, the software checks the objects from the volume query against the list of filters in the specified view style.
If an object in the volume matches one of the specified view style filters, the software applies the rules set for the object filter. If the object does not match a filter, it is not included in the drawing view.
The following conceptual graphic shows the workflow for creating volume drawings:
The software applies the view styles in a top-down manner. If an object finds its match in several filters, the last one applied (the bottommost style) overrides any preceding style rules.
When a drawing is updated, it can be published by right-clicking the document and selecting Publish on the right-click menu. The document is published as a viewable graphic file; no physical data is published.
