The options allow creating the line tangent to an ellipse and a circle at the same time. For constructing the
line, bring the cursor to the given ellipse and press (if the object snap mode is on, then it is sufficient
just to press pointing at the ellipse). After that, dynamic image of the created line will end up being
tangent to the ellipse for any cursor translations. Then point at the circle and press . Tangency points
with an ellipse and a circle (in case of non-uniqueness of the solution) will be selected by the system from
the condition of maximum closeness to the cursor location upon selecting the ellipse and the circle.
,
With the help of these options the line tangent to two ellipses can be constructed. For constructing the line,
point at two ellipses successively: bring the cursor to the first ellipse and press , then repeat the same
operations for the second ellipse.
,
This option sequence allows creating a line tangent simultaneously to an ellipse and a spline. Bring the
cursor to the required ellipse and press . Dynamic image of the cursor will become tangent to the
selected ellipse. After that, move the cursor to the spline, which a created line should be tangent to, and press
.
