Lock Radius (Circles, Spheres, & Cylinders). Allows you to specify a radius for the resulting geometry. SA will orient the specified geometry to minimize errors in the fit.
Lock Focal Length (Paraboloids). Allows you to specify a focal length for a paraboloid. SA will orient the paraboloid to minimize errors in the fit.
Lock Included Angle (Cones). Allows you to specify the apex angle for a cone. SA will orient the cone to minimize errors in the fit.
Standard [Geometry]/Max Inscribed/Min Circumscribed (Cylinders, Circles, and Slots). Specifies a different type of fit for cylinders, circles, or slots. Standard performs a traditional fit by minimizing errors. Max inscribed finds the largest geometry that fits inside the specified points, whereas Min Circum- scribed finds the smallest geometry that fits around the specified points.
Round/Square (Slots). Used to specify whether a slot should be round or square.
Guess Before Each Fit/Use Last Fit As Guess/Use Object As Guess (Cylinders, Paraboloids, Cones). Specifies how the initial condition for a fit is determined. Due to the nature of these fit types, the initial condition for the fit can have an effect on the resulting generated geometry. For example, if there is not great axial or radial coverage of a cylinder, it is possible for the cylinder fit algorithms to get “confused”. This option helps the fit algorithms find the proper solution. Guess Before Each Fit asks the algorithm to take a guess as to the initial size and orientation of the geometry before it progresses through the fit to
