The command can be called in one of the following ways:
Icon 
Ribbon 

Draw > Construct > Ellipse Workplane > Construct > Ellipse 

Keyboard 
Textual Menu 
<EL> 
Construct > Ellipse 
Ellipses in TFLEX CAD are constructed by defining their geometrical relations with other construction entities. Examples of such relations are the ellipse center being snapped to a node, tangency to a line, tangency to a circle, passing through a node, symmetry with another ellipse. Combining several options allows creation of ellipses with various geometrical relations (see Methods of Creating Construction Ellipses). Ellipses, like other construction entities, are displayed in a nonprintable thin dashed line.
Automenu options
Following options are available upon calling the command:
<T> 
Select Center Ellipse Node 

<T> 
Select a Node of Ellipse 
These mutually exclusive options are two main ellipse creation modes. In the first mode ellipse creation begins with specifying its center, in the second mode  with specifying a node for the ellipse to pass through.
<N> 
Select Node 
This option can be used in various ellipse creation methods for selecting 2D nodes.
<C> 
Select Tangent Circle 
See Construction Ellipse Bitangent to Circle, through Node and Construction Ellipse Bitangent to Circle, Tangent to Line.
<P> 
Ellipse Parameters 
Invokes the ellipse parameters dialog.
<A> 
Select axis of symmetry (straight line) 
See Construction Ellipse Symmetric to Other Construction Ellipse.
<W> 
Select 2D projection 
See Construction Ellipse Based on 2D Projection.
<F4> 
Edit Construction 
Invokes the 2D construction elements editing command.
<Esc> 
Exit command 
When working with the ellipse creation command, the set of available options may vary depending on the applied ellipse creation method and stage of executing this method.
During selection of source elements for creating an ellipse, you can cancel the selection and return to command's initial state using the following option:
<Esc> 
Cancel selection 
Creating 2D Nodes
At any stage of working with the command, pressing <Space> creates a connected 2D node at the nearest (to the cursor) intersection of construction lines. If a 2D node already exists at the nearest intersection, or if there are no intersections on the current page, then pressing <Space> has no effect.
