Lines
By using the option twice, the line tangent to two splines will be created. For constructing the line,
bring the cursor to the first spline and press . Then repeat the same for the second spline. Similar to two
previous cases, if different solutions for touching the splines and a created line can be found, tangency points
will be selected by the system from the condition of maximum closeness to the cursor location upon
selecting the splines.
,
This option sequence allows creating the line parallel to another line and tangent to an ellipse. Bring the
cursor to the line, which has to be parallel to the new line, and press . Then move the cursor to the
ellipse which a created line has to touch and press .
,
For constructing a line tangent to an ellipse and angular to another line, bring the cursor to the ellipse which
the created line has to touch and press . Then point with the cursor at the line at an angle to which the
created line has to be drawn, and press . After that, it is necessary to specify the angle between two lines
(in degrees) directly in the drawing window or in the properties window.
