To Create a Detail View With an Ellipse as Its Border (AutoCAD Mechanical Toolset)

You can use any closed contour (placed on an Inventor linked drawing view) to encapsulates the area to detail.

Note: Inventor Link is available only on 64-bit systems, and it is not installed by default.

Before you begin, create a base view of a part. Make sure you are working in the Drawing tab and the Base View icon in the Browser is highlighted.

1. In the drawing area, right-click and choose New View.
2. In the Create Drawing View dialog box:
   • View Type: Detail
   • Scale: Enter a value for the view scale.
   • Accept the other defaults, and then choose OK.
3. Select the vertex in the base view to attach the detail view.
4. On the command line, enter e to create an elliptical viewport border, and then press ENTER.
5. Specify the center point for the elliptical area.
6. Specify the radius of the X axis.
7. Once you define the X axis, move the mouse back and forth or up and down to define the Y axis. You have complete control to create the desired elliptical shape.
8. When you have created the desired shape, click the mouse button.
9. Specify the location for the detail view by moving the mouse until the elliptical viewport is in the desired location, and then click the mouse button.
10. Press ENTER.
