Insert Unit

Command Button
Command Path	Graphics - Insert - Unit
Short Cut Key	Ctrl+I

This will open the Insert Unit dialog box, as shown below:

Steps:

1. Select the required model from the tree on the left hand side of the dialog box. This contains all unit model types available for use in the project. It will default to last unit selected, or the first unit on the list if creating a new project.
   • NOTE: Steps 2 to 5 are all Optional, the user need only select the required model and then insert it into the flowsheet, step 6.
2. The unit model's tag name may be typed into the Tag field. Each unit type has its default name. This tag name may be changed at anytime. Please see Change Tag Button in the Access Window.
3. If necessary, use the drop down list to change the graphics Group. (To access a FULL list of the graphic bitmaps choose *All* in the drop down list)
4. Choose a graphics symbol from the list of the available graphic bitmaps for the chosen Group. More graphic bitmaps are available in the SysCAD91\BaseFiles\Symbols folder. See Graphics Database.
5. The unit's Rotation or Scale can be modified by typing the required values into the relevant boxes before the unit is inserted. The Scale/Rotate function can be used to change the scale and rotation after the unit is drawn.
   • HINT: To mirror the graphics symbol along the x-axis, type a negative number into the X-Scale box. To mirror the graphics symbol along the y-axis, type a negative number into the Y-Scale box.
6. To insert the unit, click once on the appropriate position in the Graphics Window with the left mouse button.

   The selected unit will be drawn on the Graphics Window. If the unit needs to be positioned precisely on the Graphics Window, when drawing the unit, you can left click and hold down, cross-hairs will appear to help you position the unit's graphics symbol. The coordinates of the cross-hairs are displayed in the bottom right hand corner of status bar. The coordinates are updated as you move the cross-hairs. Release the mouse button to insert the unit.

7. Once you have inserted the unit, you can click OK on the Insert Unit dialog box to accept the unit. If you wish to cancel the Insert Unit command, select the Cancel button, or hit the Esc button on the keyboard. These actions will close the dialog box.

NOTES:

1. You can insert more than one unit at a time by not clicking the OK button after each insert. That is, insert the first unit and then select another unit from the list and insert it. Only click on the OK button when all units are inserted. If the same unit type is required, you may position each unit by clicking its position on the drawing, without re-selecting the unit type.
2. The model type for a unit cannot be changed once it has been inserted.
3. Users can change the Graphics Symbol after the unit has been inserted. See Change Symbol.
4. The Hide Tag check box will show or hide the tag name when drawn on the Graphics Window. The Tag Position, Show or Hide function can be used to display or hide the tag name after the unit is drawn.

Insert Link

Command Button
Command Path	Graphics - Insert - Link
Short Cut Key	Ctrl+L

This command is required to connect two unit operations together with a pipe or link model. The link is constructed by choosing the Source and Destination units, and then the lines are drawn on the Graphics Window to visually display the model. To insert a link, do the following:

1. Select the Insert Link command.
2. Move the cursor over the Graphics Window. (Note that the cursor will change to the Source pointer.) Click on the Source unit for the link.
   • If the unit selected contains two or more connection points, e.g. overflow or underflow connections, you will be presented with a pop up box listing all the connection points for the unit.
   • Available connection points are black and unavailable connection points are grey.
   • The number enclosed in [ ] refers to the number of connection points available.
   • You must choose a connection point by highlighting it when the pop up box appears.
3. The cursor will then change to the Destination pointer. Click on the second unit operation. Choose its connection point if required as before.
4. The Insert Link dialog box will appear:

   

   (These options are described fully below)

5. The user may then either accept the automatic link drawn by SysCAD (if this option is selected in the Graphics list), or they may overwrite the link, as follows: The mouse cursor will change to the POINT pointer. If you have selected the orthogonal line option, SysCAD will draw only horizontal or vertical straight lines. The user must click the mouse button once to mark the first point of the line - usually this is the outlet from the source unit. Click the mouse button to indicate where the line changes direction, if required. (You can hold the mouse button down to activate the cross-hairs to assist with positioning the points.) Keep repeating this until the link is complete.
6. Click on the OK button to accept the line as drawn, or the Cancel button to cancel the insert link command.

Insert Link Dialogue Box

1. Tag - the default link tag will be displayed. The user may change this tag when inserting the link, or they may change it at a later stage, see Change Tag Button in the Access Window.
2. Hide Tag - If this is enabled then the tag will not be displayed on the flowsheet. The user may show or hide the tag at any later stage using the Show or Hide Tag command.
3. Model - There is only one model available currently, so this cannot be changed.
4. Graphics - The List box under Graphics allows the user to select the automatic link drawing method. How this works is SysCAD will try and draw a link from the selection points made during the Source unit and destination unit selection phase and draw the line segments based on the option chosen. If the user approves of this line, then it can be accepted by pressing the OK button; otherwise the user can override the auto line by manually drawing in a new one. The auto line will disappear if the user clicks on the graphics page before clicking on the OK button. The valid options are:
   • Digitized points - The user manually draws the points, no auto link graphics will be displayed.
   • Select points (single segment) - a straight line will be drawn between the two selection points.
   • Select points (orthogonal) - a combination of straight horizontal and vertical line(s) will be drawn between the two selection points.
   • Mid point (single segment) - a straight line will be drawn between the mid points of the two selected unit operations.
   • Mid point (orthogonal) - a combination of straight horizontal and vertical line(s) will be drawn between the mid points of the two selected unit operations.
5. Arrow Style - The user can choose the positions of the arrows on the link. The default is to insert an arrow at end of each direction change and at end of the last segment.
6. Scale - The user may change the size of the arrows may increasing or decreasing the scale.
7. Back Button - While drawing the segments for the link, the Back button will allow the user to go back one segment at a time to correct any mistakes.
8. Orthogonal and Non-Orthogonal Buttons - The user may select either orthogonal and non-orthogonal (free) lines or a combination of the two.

   HINT: you can switch between the options while drawing different segments of the link.

9. Line Break Button - The user can insert a break into a link, see the example below.

In the example above, the green crosses indicate user's left mouse clicks, once two points are selected, SysCAD will join them with a line. You can have either orthogonal or angled lines, based on the dialog box selection. If you selected a point in the wrong spot, just press the back button to go back one step at a time. To draw a line with a break, either press the break button or hold Ctrl key while left click when drawing the point (as indicated in the example above).

NOTE: The appearance of the link can be redrawn later using the Redraw Link function.

Insert Text

Command Button
Command Path	Graphics - Insert - Text

This command will open the Text dialog box.

To insert new text:

1. Type the required text into the New Text field,
2. Select the text size, width and rotation
3. Move the mouse cursor onto the graphics window, noting that the cursor will now read POS.
4. Click on the graphics window to place the text in the required position. The text is bottom left aligned. You can keep clicking to reposition the text to a different position.
5. Once the new text is inserted, press Create Next to insert another string or Done to finish.

NOTES:

1. If no text is entered in the New Text field, the word Text will be inserted.
2. This dialog box is used for the Change Text function. To edit an existing Text string, press Select Next, then change the Text, Scale, Rotation or Width and press Apply.

Insert Symbol

Command Button
Command Path	Graphics - Insert - Symbol

This command can be used to insert a graphical symbol which has no mathematical model behind it, i.e. "dumb" graphics (see Manipulating Graphics for information). One possible use of this is to insert a border onto a flowsheet.

The command opens the Insert Symbol dialog box:

Graphics are selected and inserted in the same way as graphical symbols are changed (see Change Symbol). Choose the graphical symbol desired and insert onto the flowsheet with a left mouse click. The graphics group can be changed via the Group drop down list. For a list of all symbols, choose *All*.

Once all the graphic symbols desired have been inserted press OK.

Insert Group

Command Button
Command Path	Graphics - Insert - Group

This command inserts a group of SysCAD models which has been saved using the Create Group command.

After a group of models has been saved to the neutral database, it can be inserted into any projects that have access to the basebase.

To insert a group, click on the graphics window and then select the Insert Group command. This will open the Insert Group dialog box.

For Example:

In the above example, some key features are highlighted. There are a few main points to note here:

1. The model information is retrieved from a neutral database.
2. In the Create Group section example, we have assigned the Group with Alumina:Digestion. When this is done, we have created a Group called Alumina, with a sub folder called Digestion. In practice, user can then save other flowsheets in the same manner, eg, Alumina:Washers etc.
3. Find and replace tags - this is optional, but should be used if the copied group is to be inserted into the same project to avoid duplicate tag names. In the above example, we have asked to Add Suffix to all the tags.
4. The Current Status line will display any duplicate tag errors if any. You will not be allowed to proceed if duplicate tag is found. In that case, press the reset button and start again.
5. Once all the options have been specified and the current status displays Ready to insert at Dig Pt, move the mouse cursor over to the graphics window and LEFT click to insert.
6. Once the models are inserted, press Done to close the dialog box.
