Customizing-BricsCAD-–-Introduction-–-P13.png

In this post, you learn about the BricsCAD® Quad, what does it, how you use it and how can you customize it in BricsCAD.

The trend in CAD user interface design is to move more of the action to the cursor, and so Bricsys® developed the Quad interface to do just that: it allows us to select commands very near to the cursor.

The Quad is somewhat customizable. BricsCAD uses workspaces to determine which groups of commands are displayed by the Quad, just as with the Ribbon. This means that commands specific to BricsCAD Mechanical appear in the Mechanical workspace, BricsCAD BIM commands in the BIM workspace, and so on.

The Quad also uses entity recognition to determine which commands are suitable at the moment, especially when it comes to editing. Select a 3D solid and solid editing commands appear.

The content of the Quad's interface is changed through the Customize dialog box, and that is the subject of this post.


The following topics are covered in this post:

  • Understanding how the BricsCAD Quad works
    Customizing the commands and groups displayed by the BricsCAD Quad

QUICK SUMMARY OF THE BRICSCAD QUAD VARIABLES

To turn the Quad cursor on and off, press the F12 function key; there is no "Quad" command. The following variables control the look of the Quad.

QuadAperture --- specifies the area to search around the cursor for entities, sized in pixels

QuadCommandLaunch --- determines if the Quad launches with the application

QuadCommandSort --- specifies the sort order of the commands

QuadDisplay --- toggles the display of the Quad cursor

QuadExpandDelay --- specifies the delay before expanding the Quad (in milliseconds)

QuadExpandTabDelay --- specifies the delay before expanding underlying buttons

QuadExpandGroup --- specifies how groups expand

QuadGoTransparent --- toggles whether the Quad goes transparent as the cursor moves away

QuadHideDelay --- specifies the delay to display the Quad following mouse movement (in msecs)

QuadHideMargin --- specifies the area in which the cursor keeps the Quad alive

QuadIconSize --- toggles the Quad between displaying small, large, or extra-large icons

QuadIconSpace --- specifies the spacing between icons

QuadMostRecentItems --- determines the number of most-recent items displayed on the Quad

QuadPopupCorner --- locates the Quad relative to the cursor

QuadPropertyUnits --- determines the automatic formatting of units when InsBase is not zero

QuadShowDelay --- specifies the Quad's display delay after an entity is highlighted

_QuadTabFlags --- determines the style of the Quad

TooltipDelay (new in v20) --- specifies the delay before tooltips appear (in msecs) in Quad, Ribbon, and Properties

QuadWidth --- specifies the width of the Quad, in columns

ON THE STATUS BAR

On the status bar, click QUAD to turn it on and off. Right-click the button to reveal this shortcut menu:

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 1-1

Show Quad on Hover --- QuadDisplay = 1

Show Quad on Select --- QuadDisplay = 2

Show Quad on Right-click --- QuadDisplay = 4

On/Off --- toggles display of Quad, like clicking QUAD on the status bar (QuadDisplay = -1)

Customize Quad Items --- displays the Workspaces tab of the Customize dialog box for changing the commands and groups displayed by the Quad.

Settings --- goes to the Quad section of the Settings dialog box


ABOUT THE QUAD

The Quad interface is unique to BricsCAD. It incorporates information about entities, along with drawing and editing functions into a rectangle that's right next to the cursor.

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 2-1

The Quad cursor, fully expanded

STEP 1: MOVE THE CURSOR ONTO AN ENTITY

Most of the time, the Quad is not visible; most of the time, you see the usual crosshair cursor. When, however, you pass the cursor over an entity, the entity highlights and the Quad appears as a single button. See the figure below. (If you do not see the Quad, then turn it on by clicking QUAD on the status bar or pressing the F12 function key.)

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 3

Initial appearance of the Quad

The initial button shows two things:

  • Last-used Command --- on the left is the command (shown by the icon) that you last accessed on the Quad
  • Rollover Tooltip --- to the right of the icon are several properties of the highlighted entity (if RT is turned on at the status bar)

Last-Used Command. The single button is the icon of the last-used command. By clicking it, you can quickly repeat the last command multiple times.

Rollover Tooltip. The name and the list of the entity's properties are together called a "Rollover Tooltip," because it appears when the cursor "rolls over" an entity. (If the Rollover Tooltip does not appear in the Quad, then click the RT button on the status bar to turn it on.)

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 4-2

By moving the cursor into the Rollover Tooltip, you can change the properties of the highlighted entity. Click on a property value, such as Color, to see a droplist of options.

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 5

Changing the properties of the highlighted entity

You can change the properties listed by the Quad on a property-by-property basis.

Step 2: Expand the Quad

As you move the arrow cursor into the last-command-used button, the Quad expands to show additional buttons. Usually, these are the commands that are commonly used with the highlighted entity. Click a button to execute its command.

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 6

Quad expanding when the cursor passes over it

Step 3: Move Into Groupings

Below the first row of commands is a row of blue boxes. These are headings and they hold groups of related commands. When you move the arrow cursor down into a blue box, such as Modify, more commands appear, in this case, related to modifying entities. Some groups of commands are for operations common to any entity, while others might be specific to the entity that is highlighted.

The commands you see in the Quad vary according to the workspace.

Identifying Icons. To see the meaning of an icon, pause the cursor over a button and then read the description in the tooltip.

TUTORIAL: DRAWING WITH THE QUAD

The Quad can start up drawing commands, as well as editing ones. The process, however, is different from using the Quad for editing, because there is no existing entity over which to hover! To draw with the Quad, follow these steps:

  1. Turn on the Show Quad on Right-click option by right-clicking the QUAD on the status bar and then selecting the option.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 13

    Turning on Quad's ability to draw entities

  2. Right-click in the drawing area. Notice that the Quad appears with drawing commands.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 10

    Quad displaying drawing commands

  3. Select one and then begin drawing the entity.

Tutorial: Dimensioning with the Quad

The Quad is especially handy for dimensioning entities quickly. The speed is due to two presets: dimensioning commands use the Entity option by default and the Quad knows which entity is selected.

To dimension an entity, follow these steps:

  1. Pause the cursor over the entity.

  2. Move the cursor into the Quad's Draw section.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 11 (1)

    Selecting a dimensioning command from the Quad

  3. Click a dimensioning command. Notice that it was dimensioned without you having to select the entity.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 12-2

    Entity is dimensioned

The same thing happens when dimensioning a line with two extension lines: all it takes is a single click.

MODIFYING THE QUAD'S BEHAVIOR

To make the Quad work differently from its default settings, take a look at the Quad section of the Settings dialog box. The fastest way to get there is to right-click QUAD on the status bar and then choose Settings in the shortcut menu.

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 1-1

Accessing Quad settings quickly

In the Settings dialog box, you can change the look of the Quad through the following variables:

  • Display the Quad only when an entity is selected (QuadDisplay variable = 2)
  • Have the Quad pop up at a different location (QuadPopUpCorner)
  • Make the Quad icons larger or smaller, tighter or wider (QuadIconSize and QuadIconSpace)
  • Control the appearance of rollover properties (RolloverTips and RollOverOpacity) See boxed text for the full list.

Customizing the Quad

The Quad has been under a great deal of development from when it was first introduced. It seems to get new functions with every release. For instance, the Quad Reactors section was added to BricsCAD V17. But in terms of customization, V17 removed the Quad tab from the Customize dialog box, and moved its content to the Workspace tab, under Quad Groups. But with V18 the Quad tab returned!

Until V18, all parts of the Quad were hard-coded, meaning we could not change them. Despite its presence in the Customize dialog box, the only customization available was whether (or not) to display predefined groups.

With V18, full customization became available:

  • You can add and remove buttons from groups
  • Create and destroy groups
  • You cannot, however, edit the properties of existing buttons, such as the Title or Command fields

To customize the Quad, enter the Customize command and then choose the Quad tab. Alternatively, right-click the Quad itself (or right-click QUAD on the status bar), and then choose Customize Quad Items.

    Click Yes to finalize the removal.

CUSTOMIZING QUAD TABS

A tab is a group of buttons. Think of tabs as toolbars or Ribbon panels. Typically, similar commands inhabit a tab, such as for editing or constraints. The figure below shows tabs named Model, Draw, and so on.

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 21

Tabs in the Quad

To edit tabs in the Quad:

In the Customize dialog box's Quad tab, right-click the name of a tab. Notice the options available:

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 22-1
Right-clicking a Quad button

The options have the following meaning:

  • Insert Quad Tab --- adds a new tab, empty of commands
  • Insert Copy --- makes a copy of the selected tab, and then prompts for a new name
  • Delete Quad Tab --- removes the tab from the Quad
  • Append Quad Button --- adds a button to the current tab; see the previous tutorial

Tutorial: Adding Tabs

To add a tab to the Quad, follow these steps:

  1. Right-click a tab name, and then choose Insert Quad Tab from the shortcut menu.

  2. Notice the Add Quad Tab dialog box. Enter a label and a title.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 23-1

    Naming the new tab

    For this tutorial, enter the following:
    Label New Tab
    Title Tab tutorial

  3. Click OK to dismiss the dialog box. Back in the Customize dialog box, notice that the new tab name is added above the one you selected.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 24-1

    New tab added to the list

  4. The tab is unpopulated, so add a button by following these steps:

    1. Right-click the new tab, and then select Append Quad Button.

      Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 25

      Adding a button to the new tab

    2. Notice the Add Quad Button dialog box. For this tutorial, choose a drawing command, such as Draw > Ray.

    3. Click OK to close the dialog box. Back in the Customize dialog box, notice that the new tab sports the new button.

At this point in the tutorial, we pause.

Where's My New Tab?

You might think that the new tab will now appear in the Quad, like a new menu or a new ribbon panel --- but not so fast. Probably, it won't. That's because the appearance of a tab depends on how the workspace is set up.

Is the tab part of a workspace? The appearance of tabs is controlled by the workspace, as described next.

Tutorial: Turning On Quad Groups (Tabs)

The Workspace tab of the Customize dialog box specifies which Quad tabs are allowed to be displayed. (Quad tabs used to be called "groups.") No tab is seen until its name is added to the Quad Tabs section of a specific workspace. If you want the tab in every workspace, then you have to add it over again to each one.

  1. In the Customize dialog box, click the Workspace

  2. Open the Drafting workspace by clicking the + (node) next to it.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 26-1

    Quad Tabs section of the Workspaces tab

  3. Open the Quad Tabs section. Notice that the new tab you created is not listed. Similarly, when you scroll through the Available Tools listing, it is not there, either.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 28-1

    Getting ready to append a tab

  4. Right-click Quad Tabs and then choose Append Quad Tab from the shortcut menu.

  5. Notice the Select Quad Tab dialog box, which lists the names of tabs you can add to the workspace. The tabs are listed in alphabetical order by their labels (such as "Tab tutorial"), rather than by their titles (such as "New Tab") because labels are more descriptive.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 29-1

    Selecting the tab to add

    Select "Tab tutorial" and then click OK.

  6. Notice that the tab is added to the workspace, under the name "New Tab."

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 30

    "New Tab" added to the 2D Drafting workspace

  7. Let's see if the new tab appears in the Quad. Click OK to close the Customize dialog box.

  8. In the BricsCAD drawing area, right-click to display the Quad in drawing mode. Move the cursor to display the tabs and then the content of the "New Tab" tab.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 31

Toggling Quad Tabs

You have to add a tab to the Quad Tabs section to make it appear in the Quad. But you don't need to remove it to hide it. Instead, change the value of its Display parameter, as shown in the figure below:

Confirming the deletion

However, if you are removing the last reference of a Quad tab in all workspaces, then there is an extra layer of safety:

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 35

A workaround is to create a dummy workspace and store your custom Quad tabs in it.

ABOUT QUAD ENTITY FILTERS

Entity filters are what BricsCAD uses to determine which commands to display. An entity filter is a piece of programming code that reacts to (filters) the entity found under the cursor. For example, when the selected object is text, then the Quad shows commands specific to text --- in addition to the All Entities section.

(Entity filters were named "Quad Reactors" in BricsCAD V17, and before V17 were known as "Custom." In those releases, reactors could only be toggled on or off. Even today, in one shortcut menu they are called "Custom Alias," and in one dialog box, they are called "Entity Alias." )

You can customize filters for the Quad commands (buttons) that you create. Quad items that are built by Bricsys cannot be changed, and so are shown in gray, as illustrated below.

Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 36

Filters cannot be edited for pre-made Quad buttons

Tutorial: Changing Entity Filters

To specify the entities that your custom Quad button should recognize, follow these steps:

  1. In the Quad tab of the Customize dialog box, select a command in your custom Quad Tab. For this tutorial, the Quad Tab is named "Tab tutorial.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 37-585x485

    Select a Quad Button item

  2. Look down to the Quad Button pane. Notice that you cannot change any property, except Entity Filter. (The other properties are grayed out.)

  3. Select Entity Filter, and then click the Browse button (found at the right end of the field).Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 38

  4. Notice the Edit Quad Button Filter dialog box, and that it lists the generic "No_Selection" filter.

    Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 39
    Current state of custom filter

  5. You can add a generic filter for all entities and/or add specific entities to be filtered.

    1. To add a generic filter, click the Add Filter button.

    2. Notice that the new dialog box also sports the title, Add Quad Button Filter.

      Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 40

      Choice of filters

      The content of this dialog box is not documented, so I am only guessing at what the options mean:
      Ojects_Any For common editing commands, such as Move and Erase. (This filter was formerly named ALL_ENTITIES.)Object_Any For entity-specific editing commands, such as PLine and AttEdit

      No_Selection For drawing commands, where no entity is selected initially. (This filter was formerly named NO_SELECTION.)

      You can also type in the name of your own "custom filter," which I think is meant for third-party developers

    3. Click OK to close the dialog box. Notice that your selection is added to the list.

    4. Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 41

      Filter added to the list

    5. Now click the Add Entity Type(s) button. Notice the Add Entity Alias dialog box

      Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 42

      Choosing an entity

    6. Choose one or more entities to which your Quad button should react, such as Arc.

    7. Click OK. Notice that again the item is added to the filter list.

      Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 43

      Arcs added to the filter list

    8. To remove a filter from the list, select it and then click the Remove button. Remove the No_Selection and Object_Any filters, leaving the Object_Arc filter.

  6. Click OK to close the Edit Quad Button Filter dialog box, and then click OK to close the Customize dialog box.

  7. Test the change you make to the button's property by drawing a line and an arc. Your custom Quad tab appears when you pause the cursor over the arc, but not over the line.Absolutely Everything You Need to Know About The Quad - Customizing BricsCAD<sup>®</sup> - 13- 42-1024x153

Left: New Tab tab appearing for an arc; right: ...but not for the line

How the Quad Works. Or, How Does It Know What Entity Is There?

Pieter Clarysse of Bricsys explains: "The cursor makes use of C++ reactors to determine which entities are nearby. The icons that appear are appropriate to the entity.

"For example, if the cursor is near an intersection, it will display the Chamfer and Fillet commands. When the cursor is over a gap between two entities, it will have the Trim and Extend commands; the size of the gap (aperture) it recognizes can be adjusted in the Settings dialog box."

To select the entity that is under the cursor in macros, use the ^S metacharacter, which is unique to BricsCAD. It is unique because ^S selects the entity without you needing to pick it. This allows for actions like dimensioning entities with a single pick: the pick consists of selecting the dimensioning command from the Quad.
