Lock Radius (Circles, Spheres, & Cylinders) checkbox: 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) checkbox: 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) checkbox: 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) drop-down list: 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 Circumscribed finds the smallest geometry that fits around the specified points.
Round/Square (Slots) drop-down list: Used to specify whether a slot should be round or square.
Guess before each fit (Cylinders, Paraboloids, Cones) drop-down button: 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 find the ideal solution, and is the default setting. Use last fit as guess uses the current geometry fit result’s size and orientation as the initial condition for the next fit recalculation. Use object as guess allows you to pick existing geometry of the same type to specify the starting condition geometry for the fit algorithm. In this way, you can provide a “hint” as to the resulting orientation of the geometry. If you find that your cylinder, paraboloid, or cone fits are not what you expect, try using this setting to help the algorithm with an initial guess.
Lock Focus Location (Paraboloids) checkbox: Prevents the current focus location from changing if a fit recalculation occurs.
Lock Vertex Location (Paraboloids) checkbox: Prevents the current vertex location from changing if a fit recalculation occurs.
