Chapter 7 Annotation Tools

7.1 Dimension Annotation Tool

7.1.1 Function Description

Dimension annotation is used to measure and annotate the distance between two points. Distance values are automatically calculated on the corresponding plane based on the current view direction:

View Direction	Measurement Formula
Plan View	√((x₂−x₁)² + (y₂−y₁)²) — XY plane distance
Front Elevation	√((x₂−x₁)² + (z₂−z₁)²) — XZ plane distance
Side Elevation	√((y₂−y₁)² + (z₂−z₁)²) — YZ plane distance

Distance values are automatically converted and displayed according to the drawing unit (e.g., when switching to meters, 1500cm displays as 15.00m).

7.1.2 Operation Steps (Three-Step Interaction)

Switch to Dimension Tool: Press D or click “Dimension” in the toolbar
Click Start Point: Click the first position in the viewport (the system automatically snaps to the nearest fixture anchor point)
Click End Point: Click the second position in the viewport
Adjust Offset: Move the mouse to adjust the distance between the dimension line and measurement line, click to confirm placement

After placing the dimension, the system automatically calculates and displays the distance value.

7.1.3 Continuous Dimension Mode

Continuous dimensioning is the most commonly used annotation method on lighting plots — continuously measuring the spacing between a row of fixtures.

Operation:

Select “Continuous Dimension” mode in the toolbar (or choose from the dimension dropdown)
Click the first fixture
Click the second fixture → Automatically annotates the spacing between the two points
Continue clicking the next fixture → The second point automatically becomes the new start point
Repeat step 4 until annotation is complete
Press ESC or double-click to finish

Features:

After committing, the end point automatically continues as the next start point
The offset distance is locked after the first setting; subsequent annotations automatically use the same offset
Highly efficient, suitable for annotating the spacing of a row of fixtures

7.1.4 Annotation Auto-Update

When annotated fixtures (or objects) are moved in the 3D scene:

If the annotation endpoints are bound to fixture anchor points, they automatically follow the movement
Distance values are automatically recalculated and updated
The dimension line geometry is automatically rebuilt

7.1.5 Cancel / Step Back

Press ESC: Step back one step (returns to start point state if end point is already set)
Press ESC again: Completely cancel the dimension tool

1	Fixture Anchor		Fixture geometric center, most commonly used
2	Annotation Endpoint		Start/end points of existing annotations
3	Grid Intersection	+	Intersection of grid lines

Snap Behavior

When the mouse is near a snappable object (within 10 pixels), the cursor automatically snaps to that point
The snap icon indicating the current snap type is displayed in the viewport
Snapped coordinates are used for precise placement of annotations/lines

Snap Toggle

The snap function can be toggled on/off via the “Snap” button in the toolbar. When off, the mouse position is unrestricted and can be placed freely.

13.2 Ortho Constraint

With ortho constraint enabled, line and annotation directions are restricted to horizontal or vertical (0/90), similar to AutoCAD’s ORTHO mode.

Control: “Ortho” button in the toolbar

13.3 Drawing Border

The border is the standard frame and title block for engineering drawings.

Control: The “Border” button in the toolbar toggles the display of the drawing border.

The border includes:

Outer frame line (thick solid line)
Title block (bottom right corner, containing project name, designer, date, and other information)

13.4 Undo & Redo

SuperCAD integrates Unreal Engine’s transaction system, supporting full undo/redo:

Operation	Shortcut
Undo	Ctrl+Z
Redo	Ctrl+Y

The following operations can be undone:

Adding annotations
Deleting annotations
Adding / deleting lines
Adding / deleting layers
Modifying layer properties
Adding / deleting pages
Assigning layers

Right-click in the viewport to open a context menu. The menu content dynamically changes based on the current selection state:

Right-Click on Empty Area

Menu Item	Function
Fit All	Zoom to show all fixtures
View Settings	Open the left panel
Refresh Scene Data	Force rescan fixture data in the scene

Right-Click with Fixtures Selected

Menu Item	Function
Locate in 3D Viewport	Focus on the selected fixture in UE main viewport
Assign Layer	Assign selected fixtures to a specific layer
Delete	Delete selected annotations/lines

Right-Click with Annotations/Lines Selected

Menu Item	Function
Assign Layer	Assign selected annotations/lines to a specific layer
Set Line Style Solid/Dashed	Modify the line style
Delete	Delete selected annotations/lines

13.6 Unit Switching

SuperCAD supports the following drawing units:

Unit	Abbreviation	Description
mm	mm	Default unit
cm	cm	Matches UE internal coordinates
m	m	Common engineering unit
ft	ft	Imperial unit
in	in	Imperial unit

Switching Method: Unit dropdown on the right side of the toolbar

After switching units:

Status bar coordinate display is automatically converted
Dimension annotation distance values are automatically converted (e.g., 150cm 1.5m)
Grid ticks adapt to the new unit

13.7 Fixture Information Display

SuperCAD automatically displays technical information next to each fixture. The types of information displayed can be controlled through document settings:

Info	Format	Color	Example
DMX Address	U{Universe}.{Address}	Cyan	U1.001
Fixture Number	#{FixtureID}	White	#001
Fixture Type	Profile name	Light Gray	Robe BMFL Spot
Power	{Wattage}W	Orange	800W
Weight	{Weight}kg	Red	25kg

Auto Update: Fixture information is collected in real time by the scene crawler. When fixtures move in the 3D scene, DMX configuration changes, or fixture profile properties are modified, the information in the CAD view is automatically updated.

LOD Control: At farther zoom levels, fixture labels are automatically hidden to keep the view clear.

Chapter 15 FAQ

Q1: Viewport is blank after opening SuperCAD?

Cause: No fixture Actors in the scene.

Solution:

Confirm that SuperDMX fixture Actors (ASuperDmxActorBase and its subclasses) have been placed in the UE level
Press F to fit all, centering the viewport on the fixture area
If fixtures exist but are not visible, check if layers are hidden in the Layer Panel

Q2: Address codes and numbers are not displayed next to fixtures?

Cause:

Labels are automatically hidden at far zoom levels — try zooming in
Fixtures are not configured with DMX addresses or profiles — check the fixture Actor’s property settings
Information display may be turned off — check document display settings

Q3: Annotation distance values are incorrect?

Cause: Annotation distances are calculated on the plane corresponding to the current view direction (projected distance), not the true 3D distance.

Solution:

Annotations in Plan View measure distances on the horizontal plane (XY)
To measure height differences, switch to Front Elevation or Side Elevation views

Q4: How to modify a placed annotation?

In the current version, annotation text content cannot be directly edited after placement. To modify:

Select the annotation using the Select tool
Press Delete to remove it
Recreate using the annotation tool

Q5: Exported DXF file won’t open in AutoCAD?

Solution:

SuperCAD exports DXF R12 format, compatible with all CAD software
Confirm the file extension is .dxf
Try using “Open” rather than “Import” to load the DXF file
Confirm file encoding is UTF-8

Q6: Will data be lost after closing SuperCAD?

Answer:

If the document has been saved (Ctrl+S), data will not be lost
When closing the window, if there are unsaved changes, the system will pop up a save prompt
The next time SuperCAD is opened, the last opened document will be automatically loaded

Q7: How to manage CAD documents in Content Browser?

SuperCAD documents are standard UE assets:

SuperCAD Document type assets can be seen in Content Browser
Double-click to open
Right-click Miscellaneous SuperCAD Document to create a new document
Supports standard asset operations such as rename, move, and copy

Q8: Extra yellow/red wireframes appear in the viewport?

Cause: UE Editor Builder Brush or BSP geometry auxiliary lines.

Solution: SuperCAD has built-in filtering mechanisms to automatically hide these auxiliary lines. If they still appear, try Right-Click Menu Refresh Scene Data.

Q9: How to refresh scene data?

When the 3D scene undergoes significant changes, you can manually force a refresh:

Right-Click Menu Refresh Scene Data

Under normal circumstances, the scene crawler automatically detects fixture additions, deletions, and position changes without manual refresh.

Q10: How to control fixture colors in wireframe mode?

In wireframe mode, fixture colors are determined by their layer color:

Click the layer’s color swatch in the Layer Panel
Select a new color in the color picker
The wireframe color of all fixtures in that layer updates immediately
