You can use any closed contour (placed on an Inventor linked drawing view) to encapsulates the area to detail.
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.
- In the drawing area, right-click and choose New View.
- 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.
- Select the vertex in the base view to attach the detail view.
- Specify the center point for the circular area.
- Specify the radius of the circle by moving the mouse until you have defined the desired shape of the circle, and then click once.
- Specify the location for the detail view by moving the mouse until the circular viewport is in the desired location, and then click once.
- Press ENTER.
