[Geometric Continuity] command evaluates the continuity of two curves at their end. The closest points of the two selected curves are the targets to evaluate. On evaluation, the result will be shown on the output window and the command terminates.
For the prompt
"Specify the 1st curve"
, select the 1st curve to evaluate.
For the prompt
"Specify the 2nd curve"
, select the 2nd curve to evaluate.
On the selection of the 2nd, the command will evaluate and output the results on output window. The meaning of each line is:
Continuity of the two curves at their end.
G-1 means discontinuous.
G0 means connected as broken.
G1 means connected with their tangents equivalent.
G2 means connected with their tangents and curvatures equivalent.
The positions' coordinate values evaluated.
The distance between two end points of the curves evaluated.
The tangent direction at the both ends of the curves evaluated.
Angle difference of the above 2 vectors.
The normal vectors at the both ends of the curves evaluated.
Angle difference of the above 2 vectors.
Curvatures at the both ends of the curves evaluated.
Curvature radius of the both ends of the curves evaluated. When a curvature is zero, zero will be displayed as the radius conventionally.
