If you want Freecad, Tinkercad is your choice | Video Tutorial | Laoban recommend

Tinkercad is a Freecad online platform which is easy to use. Try to build a pyramid in 5 min. Drag a "Roof" shape from the Basic Shapes panel (this naturally forms a pyramid structure).

Alternatively, use the "Pyramid" shape if available in your version.

Size Adjustment:

Select the shape and use the white square handles to adjust base dimensions.

Typical pyramid proportions: Set length and width equal (e.g., 50mm x 50mm), then adjust height (e.g., 75mm).

Precision Editing:

Use the shape's black arrow to control slope angle if needed.

Input exact dimensions in the inspector panel (appears when shape is selected).

Step Pyramid Option:

Create multiple decreasing-sized boxes stacked vertically.

Hold Alt while dragging to duplicate shapes, reducing each layer by 10-20%.

Smoothing Edges:

For smoother sides, add a cylinder shape and use "Hole" modifier to round edges.

Surface Detailing:

Use Text or Shape generators to add hieroglyph patterns if desired.

Final Touches:

Rotate using circular arrows for proper orientation.

Use Alignment tool (Top toolbar) to center your pyramid.

Export:

Click Export > .STL to save for 3D printing, or use Share button to generate a viewable link.

Pro Tip: Use the Ruler tool (Hotkey 'R') for precise measurements. For complex pyramids, combine multiple geometric shapes using Group and Ungroup functions. Save frequently using Ctrl+S. The entire process typically takes 5-10 minutes for basic structures. Experiment with different materials in the inspector panel for varied visual effects before finalizing your design.
