Draws a pyramid or tetrahedron as a 3D mesh surface.
Accessing the Command
command bar: ai_pyramid
menu bar: Draw | Meshes | Pyramid
toolbar: Draw 3D |
: ai_pyramid
Prompts you in the command bar:
First point for base of pyramid: (Pick a point, or enter coordinates.)
Second point: (Pick another point, or enter coordinates.)
Third point: (Pick a third point, or enter coordinates.)
Tetrahedron/<Last point for base>: (Pick the last point, enter coordinates, or type T.)
Ridge/Top surface/<Apex of pyramid>: (Enter an option, pick a point, or enter coordinates.)
This command draws:
Pyramids with four-sided base and four sides; the base does not need to be an equilateral.
Tetrahedrons with triangular base and three sides; the base can be scalene.
Pyramids with pointed, ridged, or flat tops.
To draw a rotated pyramid, specify the angle during the Apex option.

Description |
Specifies the first corner of the pyramid's base. |
|
Specifies the second corner of the base. |
|
Specifies the third point of the pyramid's base, or the last point for a tetrahedron's base. |
|
Specifies the fourth point for the pyramid's base. |
|
Specifies the height and angle of the pyramid; draws a pointy top. |
|
|
Draws tetrahedrons; prompts you: Apex of tetrahedron - specify the top of the tetrahedron. |
|
Draws a ridge at the top of the pyramid. Prompts you: Start of ridge specify the height and location of one end of the ridge. End of ridge specify the height and location of the other end of the ridge. |
|
Draws a flat surface at the top of the pyramid; prompts you: First point on top surface of pyramid - specify the starting corner of the pyramid's flat top. Second point - specify the next corner. Third point - specify the third corner for pyramid, and the last corner for a tetrahedron. Last point of top surface - specify the fourth corner for the pyramid. |
Grips Editing
Mesh-formed pyramids can be edited directly through grips:
Select the pyramid. Notice that it has one grip at each vertex.
Drag the grip to move the adjacent faces.
