### 7.4.1. Importing drawings; Drawings gallery

The graphical editor supports use of drawings from other applications. Such drawings are treated as “pure” graphics, which means that they cannot be part of the calculated system. Drawings are handled in the “Drawings gallery”. In this window you can load drawings, delete them, re-scale them, modify their descriptions, etc.

¨ To activate the drawings gallery (window for handling drawings), select “Modules / Drawings gallery...”.

The drawings gallery window is shown below:

The upper part of the window includes a list of drawings in the project. Some items in the list may be preceded by symbols “L” or “U”. They have the following meanings:

- “L” – the drawing is saved to user library; it is saved to project file only if it was used. Drawing without the “L” symbol is saved to project file only and is not available in other projects

- “U” – drawing used in the project.

After clicking the drawing title in the drawings list, the drawing is displayed in the lower part of the window. To zoom in or out the drawing use buttons with magnifying glass , use the scroll bars to move the drawing horizontally and vertically.

Check the box under the drawings list to save the selected drawing to user library. You can change the label of the selected drawing in the “Label” field.

Buttons for loading the selected drawing from disk, saving the drawing to disk and deleting the drawing from the list are in the upper right part of the window. Drawings may be saved in several file formats.

! It is not possible to delete a drawing that is used in the project.

Tabs for configuring drawing data are on the right side. The “Scaling” tab is used for scaling the drawing. You can move the red points anywhere on the drawing. Move both points with the left mouse button depressed to characteristic locations within the drawing and enter the distance between them in the field . The drawing is re-scaled after clicking the “Scale” button.

You can specify the dimensions of the drawing in “X size [m]” and “Y size [m]” fields. These dimensions should be specified in an absolute scale in metres. If the “Proportions” box is checked, altering one dimension of the drawing forces the other dimension to change accordingly.

On the “Connections” tab there is a field, after checking which two spots appear on the drawing. You can move these spots with the left mouse button.

This function may be used to create drawings of such components as boilers and terminal unit of specified pressure drop. It is also possible to change the drawing type for components inserted in the “Developed view” sheet. After placing the component in the workspace, change designation to “Drawing” in the “Drawing type” field of the data table and select the file saved to gallery in the “Drawing” field.

The additional field “Grid” indicates that connection points can only be moved along grid lines.

The last two fields in the right-hand side of the window have the following meaning:

- “Display scale” – scale in which the drawing is displayed,

- “Show size” – a blue broken line indicates the drawing border.

! The program enables importing graphic files in the DWG, DXF, WMF, EMF, BMP, JPG format and others. When a DWG/DXF file is selected for loading to the gallery, the import window is opened.
