When filleting or chamfering an edge, the user is given the unlimited ability to increase the size of the feature via the GUI arrow. Upon dragging the arrow, other body features can cause the fillet/chamfer to generate an error, that will prohibit the creation of the new feature. For instance, if there is a 10.5 x 10.5 x 10.5 unit cube, the maximum chamfer that can be created is 10.5 units. However, the step size that the chamfer GUI provides increments as an integer of 1 unit. This means the the largest chamfer able to be set by the GUI is 10 units as an 11 unit chamfer would cause an error. Instead of jumping from 10 to 11 units the GUI should step through 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 to 10.5 units (the max chamfer possible) and stay there until the GUI arrow is used to decrease the size of the chamfer. The current implementation reguires the user to know in advance the size of the cube and manually set the chamfer value if the maximum feature size is desired. Recommend that when the fillet/chamfer becomes too large, the value in the dialog box is set to the largest possible value that would not result in an error condition, illiviating the user's need to guess or preordane the correct value. This is a minor annoyance and the user has the ability to workaround the issue but it should be corrected when practicable.
