Introduction

This is a subset of the graphics commands which are used to draw and manage SysCAD flowsheets.

Note: SysCAD must be in the Edit mode (stopped) for most of these commands to be accessed.

Tag Position, Show or Hide

Command Path Graphics - Edit - Tag Position, Show or Hide

This command is used to show or hide unit display tags. The scale, rotation and position of the unit tags can be changed using the Update tag annotation dialog box.

There are two parts to this command:

  1. If the Set tag position option is not ticked, the following dialog box is visible:
    Update Tag Annotation.jpg
    • You can show, hide, or change the size or rotation of the tags by clicking on the unit/s of the active Graphics Window.
    • The selected unit/s will turn magenta. When you have selected all the required units, either by clicking on them one by one, or using the IWin and CWin buttons to make group selections, press Apply.
    • Alternatively, the Show All or Hide All buttons can be used.
  2. If the Set tag position option is ticked, then following abbreviated dialog box is visible:
    Update Tag Annotation2.jpg
    • (To see the full dialog box, merely untick the Set tag position option)
    • You may reposition the unit tag on the active Graphics Window one at a time.
    • Move the mouse cursor over the Graphics Window, the cursor will display UNIT.
    • Click on the unit tag you wish to reposition, and the unit will turn magenta and the cursor will now display POS.
    • The tag can be moved by either:
      • Clicking on a new position for the tag. You can keep positioning the tag by mouse clicks until you are satisfied with the new position.
      • NEW in SysCAD 9.3, tag can be moved using the arrow keys.
    • When you are ready for the next tag, press Next in the dialog box and repeat the above process.
    • Press Done when finished.

Note:

You may see a short video on the Editing Tags functionality at Basic Tutorial - Edit Tag Displays.

Move

Command Path Graphics - Edit - Move

Graphics symbols can be moved individually or in a group on the currently active Graphics Window using either:

Move (button or command) opens the following floating toolbar:

MoveToolbar.png

(Note the Grid tool bar buttons are only available in SysCAD 9.2 Build 134 and later)

  • Move the mouse cursor over the active Graphics Window and the cursor will display GRF. Select the entity you want to move by clicking on the unit once if moving a single unit; or draw a box around the units using the in-window and cross-window buttons. If the selection is incorrect click once away from the selected graphics and try again.
  • Drag and Drop: Pick a point on the selected graphics (for lining up with other symbols, eg, corner of a tank), click on the point and hold down. Use the cross hairs to re-position the graphics symbol. Release the mouse button to complete the move.
  • Arrow Keys: Hold down the relevant arrow key to move the selected graphics Up, Down, Left or Right. When the graphics is in the required position, hit the Enter button, or the Tick.png button on the Move dialog box.
  • To move another graphics entity, repeat the above process.

Notes:

  1. When the graphics symbols are placed/moved manually by the user, they are snapped to small grid.
  2. To auto snap existing symbols to the big or small grid, click on the symbol(s) to the snapped, then click on either the Large Grid Largegrid.png or Small Grid Smallgrid.png option from the toolbar, the selected symbol will be "snap" to the nearest grid.
  • NEW in SysCAD 9.3, graphics can be Moved, Scaled or Rotated using the arrow keys once you have activated either the Scale/Rotate OR Move commands:
    To Move the unit, click on any of the arrow keys to move UP, DOWN, LEFT or RIGHT.
    To Scale the unit, hold down the Control key and click on the UP arrow to increase the scale, or the DOWN arrow to decrease the scale.
    To Rotate the unit, hold down the Control key and click on the LEFT or RIGHT arrow key to rotate left or right.
    To increase the movement or scaling, hold down the Shift key as well, and this will make the changes larger.

Aligning Models Horizontally or Vertically

To align models horizontally (e.g. row of tanks) or vertically (e.g. Feeders), use the in-window or cross-window button to select multiple units, then press the Big Grid button Largegrid.png. All selected units will be snapped to its nearest grid. This is best used to align multiple units that are just slightly off-alignment.

For Example:
SnapGrid3.png
  • To change the Grid size, goto Tools|General Options|Graphics Tab (Graphics). Note the grid size specification is only available in SysCAD 9.2 Build 134 and later.
  • The redraw button can be used to update the drawing.

Scale/Rotate

Command Button ScaleRotateButton.png
Command Path Graphics - Edit - Scale/Rotate

Use this button to change the scale and/or rotation for a graphics entity - unit or link on the currently active Graphics Window. It opens the following floating toolbar:

User Guide image262.gif

Move the mouse cursor over the active Graphics Window, the cursor will display GRF. Select the entity you want to alter by clicking on the unit once if changing a single unit; or draw a box around the units using the in-window and cross-window buttons. If the selection is incorrect click once away from the selected graphics and try again.

  • NEW in SysCAD 9.3, graphics can be Moved, Scaled or Rotated using the arrow keys once you have activated either the Scale/Rotate OR Move commands:
    To Move the unit, click on any of the arrow keys to move UP, DOWN, LEFT or RIGHT.
    To Scale the unit, hold down the Control key and click on the UP arrow to increase the scale, or the DOWN arrow to decrease the scale.
    To Rotate the unit, hold down the Control key and click on the LEFT or RIGHT arrow key to rotate left or right.
    To increase the movement or scaling, hold down the Shift key as well, and this will make the changes larger.
    You may see a short video using the Arrow keys at Basic Tutorial - Using Arrow Keys to Move, Rotate and Resize Graphical Units.
  • Click on the Increase Scale or Decrease Scale buttons to change the scale of the selected graphics.
  • Likewise, click on the Rotate+ or Rotate- buttons to change the rotation of the graphics entities.
  • To use customised scale up factor or rotation angle, use the Dialog button User Guide image264.jpg. Change the position, scale and rotation of the selected unit as required and press Apply.
  • To accept the change, click Accept or press Restore to retain the original setting.
  • To alter another graphics entity, repeat the above process.
  • The redraw button can be used to update the drawing.

Change Unit

Only available in SysCAD 9.2 Build 134 and later. Please also see ETip: Changing Unit Models

Command Button Change Model Icon.png
Command Path Graphics - Edit - Change Unit
Short Cut Key Ctrl+Alt+U

The actual mathematical model may be changed using this command, without changing the graphic symbol and the links will remain connected. Any unit may be changed to any other type of unit with this command.

Example

For example, the user can change a Shell and Tube Heat Exchanger to a Simple Heat Exchanger by following these steps:

  1. Click on the 'Change Unit' icon, or go to Graphics - Edit - Change Unit.
  2. Click on the unit that you wish to change.
  3. The following dialog box will be visible:

Change Unit 1.png

  • Select the new mathematical unit model from the list - ANY unit model may be selected.
  • Review the link connections and change them, if required. To change the link connection, click on the pipe tag and then select the required connection from the drop down list at the bottom of the dialog box. Note that as you select the pipe tag, the pipe is hilighted in the graphics window making it easy to see which pipe is which while checking connections.
  • When all of the link connections have been reviewed, click on the 'OK' button.

Notes:

  1. The graphical symbol for the model will NOT change. Use the Change Symbol command to achieve this.
  2. The Left Hand list contains all unit model types available for use in the project.
    • To display all unit model types available in the dlls which are loaded, enable the Show All option. This is only available in Build 138 or later.
    If the Include All Unit Models option has been enabled in the cfg file (refer to Model Selection), then all the unit model types are already displayed and this option will be greyed out.
  3. The user may use this command to change the link connections without changing the actual mathematical model. Ideal for swapping ports of connected pipes.
  4. The user may change the unit and disconnect one or more links and connect them afterwards to a different unit(s) using the Connect Link command.

Redraw Link

Command Button RedrawLinkButton.png
Command Path Graphics - Edit - Redraw Link
Short Cut Key Ctrl+Shift+L

The appearance of the link (including the arrow style and scale size) can be changed using the Redraw link function.

To redraw the link, select the link by clicking on it, this opens the redraw link dialog box, which has the same options as the Insert link dialog box:

Redraw Link 2.png
Redraw the link as described in Graphics for Insert Link and Redraw Link.
The Next button will allow the user to re-draw another link.

Notes:

  1. This does NOT change the links connections.
  2. The Secondary highlight colour functionality is only available in SysCAD 9.3.

Change Symbol

Command Button Changesymbolbutton.png
Command Path Graphics - Edit - Change Symbol
Short Cut Key Ctrl+Shift+U

The appearance of the Graphics symbol can be changed using the Change Symbol function. To change unit operation graphics Symbol:

  • Select the Change Symbol command;
  • Observe that the mouse cursor has changed to unit;
  • Select the unit operation you wish to alter by clicking on it.
Change Symbol.png

This opens the Change Symbol Dialog box as shown here.

  • You may select any graphical symbol from the list. You may also change the 'Group' to display the graphical symbols in a different group.
  • You may change the X and Y scale or the rotation of the graphical symbol.
  • You may change the graphical symbol of ALL units that are using the same graphical symbol as the one selected by clicking on the 'Change All' button, or
    You may change the graphical symbol of only the selected unit by clicking on the 'OK' button.


NOTES:

  1. For Build 135, the dialog shows the current symbol name used below the image, and in brackets the location (SysCAD, BaseFiles, BaseFilesUser or NotFound).
  2. This only changes the appearance of the Unit operation, it does NOT change the unit operation type or the configuration data associated with it.
  3. The dialog box above does allow the user to select a Graphics Symbol from another symbol group which is normally associated with a different model type.
    For example, if you want to change the symbol for a Flash Tank to a symbol in the Tank group, near the top of the dialog box, select 'Tank' from the drop down list in Group and you can then choose any symbol from the Tank group.
  4. If users wish to change the actual mathematical model, say from a Flash Tank to a normal Tank, use the Change Unit command (Only available in SysCAD 9.2 build 134 or later).

Change Text

Command Button Changetextbutton.png
Command Path Graphics - Edit - Change Text
Short Cut Key Ctrl+Alt+I

This command will open the Text dialog box.

User Guide image273.gif
  • To edit an existing Text string, press Select Next, then change the text and press Apply. You can also reposition the text by selecting a new position. The text is bottom left aligned.
  • Once the text is updated, press Select Next to change another string or Done to finish.

NOTE: This dialog box also servers the Insert Text function.

  • To insert new text, click on Create Next, type in the required text in the New Text field, 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.

NOTE: If not text is entered in the New Text field, Text will be the default insert.

Disconnect Link

Only available in SysCAD 9.2 Build 134 and later.

Command Button Link - Disconnect.png
Command Path Graphics - Edit - Disconnect Link

The user may disconnect either the source or the destination unit, or both, from a link using this command. The link will then turn red and SysCAD will not run until the user reconnects the link, using the 'Connect Link' command, see below.

Note: The graphics for the link will NOT change.

Connect Link

Only available in SysCAD 9.2 Build 134 and later.

Command Button Connect Link.png
Command Path Graphics - Edit - Connect Link

The user may connect a link to either a source or a destination unit, or both, using this command. The link must have one or both ends disconnected before this command can be used.

Note: The graphics for the link will NOT change.

Create Group

Command Button CreateGroupButton.png
Command Path Graphics - Create Group

This command allows the user to choose selected groups of SysCAD models and save them in a neutral database. Once the group of models is saved, they can be inserted onto any graphics windows, this includes different projects. This is an easy way to create multiple flowsheets that contain the same layout of models. Furthermore, the create group function enables the user to change model tags using some tag rules. With this feature, the user may more easily rename models if the models follow some logical tag naming rules.

To create a group:

  1. Open a project that contains a graphics page with the required models for copying
  2. Choose Create Group. This will bring up the floating save Group tool bar and the mouse pointer will change to read ORIGIN:
    User Guide image296.gif
  3. Select the origin by right clicking once on the required insert position.
    Note: this will mark the bottom left hand corner of the group when the models are inserted later using the Insert Group function.
  4. Once the origin is selected, the mouse pointer will change to read NODE.
  5. The user can select the required models one at a time by LEFT clicking on them or use the cross-window or in-window buttons on the Save Group tool bar.
  6. When all the models have been selected, press the tick button on the floating tool bar to confirm. This will now open a Create Group Dialog box.

For example:

User Guide image297.gif

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

  1. The model information will be stored in a neutral database.
  2. The description field must have an entry.
  3. The Groups field allows the user to assign the copied models to a group. The syntax to use here is Group:Name. See example on Insert Group section for the resulting view.
  4. 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 find tags that Starts with FT_. The Start Tag is marked by "^". You can also ask to find End Tag, just click on the ... button to the right of the field to get the options. If you have made a mistake, press the Reset button to start again. Note that it will reset all the tags and not just the last replace.
  5. The Current Status line will display any duplicate tag errors if any. You will not be allowed to proceed if any duplicate tags are found. In that case, press the reset button and start again.
  6. Once all the options have been specified and the current status displays Ready, press OK to proceed with the export of data to the database.
