ParametricExpression
An expression is a Lua string containing variables and numbers. Eg: “(1+5)*10”.
Example
application = cf.Application.getInstance() project = application:NewProject() paraboloid = project.Contents.Geometry:AddParaboloid(cf.Paraboloid.GetDefaultProperties()) -- Add a work surface onto the paraboloid face workSurface = project.Definitions.WorkSurfaces:Add(paraboloid.Faces["Face1"], 0) -- Move the worksurface using a parametric expression workSurface.Offset = 1/5 * 40
