Extrude, Boolean, and Section Plane

These tools connect KAD drawings to surface operations, enabling you to create 3D geometry from 2D design boundaries.

A closed polygon around a blast, extruded 12 m down and shown part-transparent in 3D.

Extrude KAD to Solid

Extrudes a closed KAD polygon straight up or down into a closed 3D solid, from Extrude KAD to Solid on the Surface toolbar. Choose the Polygon, set Depth (m) +ve=up, -ve=down, and click Apply. See Extrude KAD to Solid.

Use Cases

• Creating pit shell volumes from 2D outlines
• Building bench outline solids for volume calculations
• Generating exclusion zone meshes
• Creating design surfaces from plan-view boundaries

---

KAD Boolean

Union, intersect, difference and XOR of closed polygons, from KAD Boolean on the Modify toolbar. See KAD Boolean.

---

Section Plane

Slices the 3D scene along a plane so you can see the design side-on — holes, drawings, surfaces and block models. It is on the Select toolbar. Draw a line where you want the section, then choose Segment in the Section Plane dialog and click the line; or choose Two Points and click the two ends.

See Section Views.

Use Cases

• Verifying pit wall design against actual terrain
• Checking bench geometry at specific locations
• Visualising sub-surface layers
