4. Ellipse with the center at a node, tangent to line, using parameter
Upon calling the command, use the following sequence of options:
or
These option combinations create an ellipse with the first semi-axis defined by tangency to a line at the tip of
the semi-axis and the second semi-axis driven by the parameter. To create this type of ellipse, first select the
desired node as the ellipse center. Next, use the option and select the line making tangency with the
ellipse at the tip of the semi-axis. Then move the cursor over desired position and click . The exact value
of the second semi-axis length can be entered in the property window in transparent mode or in the
parameters dialog box (the option ). The required ellipse will be created.

5. Ellipse with the center at a node, tangent to line, passing through node
Upon calling the command, use the following sequence of options:
This combination of options creates an ellipse with the first semi-axis defined by tangency to a line at the tip
of the semi-axis and the second semi-axis ending at another node. To create this type of ellipse, first select
the desired node as the ellipse center, and then select the line making tangency with the ellipse at the tip of
the semi-axis. After that, select a node to define the position of the ellipse’s second semi-axis. The required
ellipse will be created.

The following techniques can be used in the mode of constructing ellipses passing through a node:
1. Ellipse passing through two nodes, using parameter
Upon calling the command, use the following sequence of options:
or
or or
These combinations create an ellipse, passing through two nodes, with the second semi-axis defined by a
parameter. To create this type of ellipse, move the cursor over the first node and press the option
or . Next, with the same options select the second node. Then move the cursor over desired position and
