Ellipse

System variable PELLIPSE controls the type of newly created ellipses.

The variable value PELLIPSE = 0 creates a true ellipse.

The variable value PELLIPSE = 1 creates a 2D polyline representation of ellipse from arc segments.

Creation of Isocircle and Isoarc

Creating circle and arc in the current isoplane.

In the commands for creating an ellipse, the Isocircle and Isoarc options are available only when the isometric mode is enabled: the Isometric snap type set in the Grid snap of the drafting settings.

Isocircle

     

1.    Enable the isometric mode.

2.    Select the command to create an ellipse.

3.    Upon the command line prompt: Specify axis endpoint of ellipse or [Arc/Center/Isocircle]: - select Isocircle.

Command prompts

Specify center of isocircle:

Specify center of isocircle.

Specify radius of isocircle or [Diameter]

:

Specify the value of semi-axis or select Diameter and specify its value.

 

Isoarc

     

1.    Enable the isometric mode.

2.    Select the Elliptical Arc CAD software Ellipse 25 Command.

When selecting the Arc option in the universal command in response to the command line prompt: Specify axis endpoint of ellipse or [Arc/Center/Isocircle]: - select Arc

Command prompts

Specify axis endpoint of elliptical arc or [Center/Isoarc]:

Select Isoarc.

Specify center of isocircle:

Specify the center point.

Specify radius of isocircle or [Diameter]:

Specify the value of semi-axis or select Diameter and specify its value.

Specify start angle or [Parameter]:

Specify a start angle.

Specify end angle or [Parameter/Inner angle]:
