Taper
Taper introduces imbalance by making one side of the shape thinner than the opposite side.
Available with: Cuboid, Cylinder, Prism, Polygon, Capsule, Ovoid
A primitive's shape parameters determine the geometry and appearance of the primitive. You can change how a primitive interacts with other primitives with the Combine parameters.
When you create a primitive, you are prompted to select a shape for the new primitive object. The available shape parameters for a primitive are based on which shape is selected.
You can change a primitive's shape by selecting the primitive and using the Choose shape button to select a different shape.
When you change to a different shape, parameters are remembered. For example, if you have a cuboid selected and set the Taper value to 50%, when you switch to a cylinder, the cylinder still has a Taper value of 50%. If you switch to an object that doesn't have a Taper parameter, the Taper value will still be remembered in case you switch to another shape, but it will only affect the appearance of a shape if that shape has the parameter available.
You can reset the shape parameters for the current primitive with the Revert button. The Revert button only affects shape parameters, it does not modify combine parameters.
While each shape has its own set of parameters, many parameters are shared between shapes. A list of all parameters is included below:
Color is the last shape parameter, and is available for all shapes. Color allows you to change the color of a shape.
If changing the Color parameter is not having a visible effect on your primitive, it may be because a material is overriding the color. To fix this:
The Color parameter is a little different from other shape parameters because it can be affected by other shapes and by the Blending slider. A non-zero Blending value allows the color of nearby primitives to blend with each other, just like the geometry is blended. Similarly if you have two overlapping primitives with different colors and your combine mode is not set to Add, the area where one primitive cuts away from the other will be colored differently.
