You will need

- - base diameter
- - the height of the cone

Instruction

1

Build X and Y axis at an angle of 120°. Vertically upward from their intersection guide axis Z.

2

Build on the axes of the rhombus whose side is equal to the base diameter

**of the cone**.3

Fill in the auxiliary rhombus oval.

4

Aside from the center of the ellipse the height

**of the cone**parallel to the axis Z.5

Swipe from the top of the

**cone**tangent to the ellipse at the base.6

Determine the visibility of lines in the drawing. Visible lines are solid, invisible, dotted line, axial - dash-dotted line.

Note

If you need to build a cone you have to build another subsidiary rhombus on the height of cut and re-enter it in the oval. This is true for the cone, cut by a plane parallel to the base of the cone. If the cut plane is positioned at an angle, then the build will be different.

Useful advice

Auxiliary building complete solid pencil, so they will be less noticeable. Visible lines are constructed of a cone circle with a soft pencil.
