Selecting the Algorithm to Fit The Features

While measuring a feature it might be necessary to use different fitting algorithm based on the different requirement in the drawing, for example, depending the application, a circle might be calculated as least square or minimum circumscribed circle.
In ARCOCAD the type of algorithm to be used can be chosen as follow:

Open the the Option Panel.
Select the tab FEATURES.
The tables show allow the associate for each feature the desired algorithm.

Note: The algorithm setting is modal, that implies that ,once set, the type of algorithm will stay active until changed or a new project is created/run.
