The ramp block will allow you to gradually change a value, based on the distance field of an object.
Real Field: The distance field driving the ramp. The object or plane that is the distance field represents the 0 mm mark for your ramp boundary.
In min/In max: The boundary where the ramp will begin (min) and end (max). These values are in relation to the Real Field (0 mm). Negative values will be below the Real Field, and positive values will be above it.
Out min/Out max: The ramp output values. Out min is the starting value at In min, and Out max is the value reached at In max. They are the new values as a function of the distance field.
Ramp functions can be applied to several types of fields - make sure to specify the output units!
The values will ramp between the In min and In max values. Before In min, the value will stay constant at the Out min value and after In max, the value will stay constant at the Out max value.
The image below shows a visual representation of the ramp block
Continuity: Represents how the values will ramp. Look at the image below to see the differences.
In the example file below:
Add the Ramp block to the thickness of an object.
In the Real Field input, drag and drop the body whose real field will determine the ramp.
