Virtual Geometry Box &
Engineering Drafter

Getting Started

Click Open Fullscreen before starting the simulation. Full-screen mode provides a larger workspace, making geometric constructions easier, more comfortable, and more accurate.

1. Select Instruments

Select the required instrument(s) from the toolbar.

• Compass – Draw circles and arcs.
• Protractor – Measure and construct angles.
• Scale (Ruler) – Measure distances and draw straight lines.
• Set Square – Draw parallel lines, perpendicular lines, and standard angles.
• Pen – Draw, write, and mark constructions.
• Eraser – Remove unwanted traces and construction marks.

Use the checkboxes in the toolbar to show or hide individual instruments.

2. Move & Rotate Instruments

Move Instruments

• Compass: Drag the needle tip to move the compass. Adjust its opening using the Radius slider.
• Protractor: Drag the center (base) to reposition it.
• Scale & Set Square: Drag any part of the instrument to move it.

Rotate Instruments

• Compass: Rotate it by dragging the pencil leg.
• Protractor, Scale & Set Square: Rotate them using the Rotate handle.

Position each instrument carefully before beginning your construction.

3. Draw & Trace Constructions

Using the Pen

1. Enable the Pen from the Floating Tool Box.
2. Click the top button on the pen to toggle tracing ON or OFF.
3. Red indicates tracing is enabled, while Black indicates tracing is disabled.
4. You can also disable tracing by clicking on an empty area of the worksheet.
5. Move the pen near the edge of an instrument until a guide circle appears around the pen tip.
6. Enable tracing, then click and hold the guide circle and drag slowly along the instrument's edge to create smooth, accurate lines.
7. Adjust the line thickness using the Pen Stroke slider in the Floating Tool Box.

Compass Pencil Trace

1. Click the compass pencil tip to enable compass tracing.
2. Click on an empty area of the worksheet to disable tracing.
3. Use this feature to draw precise circles and arcs.

4. Customize Pen Color

Change the pen trace color using the Pen Color button in the Floating Tool Box.

• Choose a color using the RGB sliders, color picker, or color palette.
• The selected color will be used for all subsequent pen traces.

Using different colors helps distinguish different steps of a geometric construction.

5. Add Text to the Workspace

1. Enter the desired text in the Text Box located in the Floating Tool Box.
2. Click the Write Text button.
3. Click anywhere on the worksheet where you want to place the text.
4. Repeat these steps to add additional text labels whenever required.

Use this feature to label constructions, points, angles, measurements, or add notes directly to the workspace.

6. Use the Eraser

1. Enable the Eraser from the Floating Tool Box.
2. Click the eraser to activate it.
3. Drag it over unwanted traced lines or text to erase them.
4. Click on an empty area of the worksheet to deactivate the eraser.
5. Adjust the eraser size using the Eraser Size slider.

Use the eraser carefully to remove mistakes while preserving completed parts of your construction.

7. Show Grid

Enable Show Grid whenever greater precision is required.

• Align instruments accurately.
• Maintain correct spacing and proportions.
• Improve the precision of geometric constructions.

8. Export Your Construction

1. Complete and review your construction.
2. Click Export Image.
3. Choose the background color when prompted:
   • OK – Export with a black background.
   • Cancel – Export with a white background.
4. Save your construction as a high-quality PNG image.

The exported image can be used in assignments, reports, presentations, classroom activities, and documentation.

9. Move the Floating Panel

The Floating Tool Box can be dragged and positioned anywhere on the worksheet for easier access while working.

Helpful Tips

• Open the simulation in Fullscreen for the best working experience.
• Position instruments before enabling tracing.
• Drag the mouse slowly for smoother and more accurate lines.
• Adjust the Pen Stroke width according to your drawing needs.
• Use different pen colors to distinguish construction steps.
• Label important points and constructions using the Write Text feature.
• Enable the grid whenever high precision is required.
• Use the eraser only to correct mistakes without disturbing completed work.
• Review your construction carefully before exporting the final image.
