Purpose

The Boundary to Solid function is used to convert closed boundary geometry into 3D solid objects. This process enables designers to transform 2D design information into intelligent 3D elements that can be used for modelling, visualisation, coordination, quantity assessment, and construction documentation.

Standard Workflow

1. Prepare Boundary Geometry

Before creating a solid:

• Open the project drawing.
• Confirm the boundary is a fully closed object.
• Verify there are no gaps, overlaps, or duplicate linework.
• Ensure the boundary accurately represents the intended feature.
• Place boundary objects on the correct layers in accordance with project standards.

2. Review Geometry Integrity

Prior to conversion:

1. Select the boundary object.
2. Verify it forms a continuous closed shape.
3. Check for self-intersecting geometry.
4. Remove unnecessary vertices where appropriate.
5. Confirm dimensions and orientation are correct.

3. Launch Boundary to Solid

To create a 3D solid:

1. Select the Boundary to Solid tool.
2. Choose the closed boundary to convert.
3. Specify the required solid creation settings.
4. Define the extrusion height, depth, or thickness as required.
5. Confirm the conversion parameters.

4. Generate the Solid

Once parameters are defined:

1. Execute the conversion process.
2. Allow the software to generate the 3D solid.
3. Review the newly created object.
4. Confirm the solid has been created successfully without geometry errors.
5. Verify the object's location within the model space.

5. Review Solid Properties

After creation:

• Check the solid dimensions.
• Verify height and thickness values.
• Confirm object positioning.
• Review layer assignments.
• Ensure the object complies with project modelling standards.

6. Edit the Solid if Required

Where design changes occur:

1. Select the solid object.
2. Modify dimensions or geometry as required.
3. Regenerate or recreate the solid if necessary.
4. Review the modified model.
5. Confirm the final result aligns with design requirements.

7. Coordinate with Other Model Elements

Before finalising:

• Review interactions with adjacent features.
• Check terrain integration where applicable.
• Verify relationships with structures, hardscape, and landscape elements.
• Ensure there are no clashes or unintended overlaps.
• Confirm model accuracy for visualisation and documentation purposes.

8. Generate Outputs

For project deliverables:

1. Include solids within 3D models.
2. Generate visualisations if required.
3. Review plan, section, and elevation representations.
4. Verify plotting and display settings.
5. Ensure model outputs meet project standards.

9. Validate and Save

Before completing the task:

• Confirm the original boundary was converted correctly.
• Verify geometry accuracy.
• Review dimensions and positioning.
• Check layer standards.
• Validate model coordination.
• Save the drawing and update project records.

Recommended Standard Practice

1. Create or verify closed boundary geometry.
2. Review boundary integrity.
3. Convert the boundary into a solid.
4. Verify dimensions and placement.
5. Coordinate with surrounding model elements.
6. Review outputs and visualisations.
7. Perform quality assurance checks.
8. Save and issue project information.

Typical Boundary to Solid Tasks

Quality Control Checklist

Before completing work:

✅ Boundary forms a closed shape
✅ Geometry checked for errors
✅ Correct extrusion height applied
✅ Solid created successfully
✅ Dimensions verified
✅ Positioning reviewed
✅ Appropriate layers assigned
✅ Coordination with surrounding objects checked
✅ Model outputs reviewed
✅ Drawing saved successfully

Outcome

Following the Boundary to Solid workflow ensures that closed design boundaries are converted into accurate and coordinated 3D solid objects. Proper use of this process supports model development, visualisation, design coordination, quantity assessment, and the production of reliable project documentation.
