The CDVIEW command lets you create a magnified details of a particular view of the drawing, clipped to a specified rectangle or circle. Such a magnified drawing view is useful in providing dimension details.
When you enter the CDVIEW command, it will prompt
asking you to determine the shape of the clipping frame for the drawing details first. You may enter the sub-command option "C" to choose a circle frame or pressing space bar for a default rectangle frame. If you designate a point to this prompt, you choose the rectangle frame. The point will be taken as a corner point of the rectangle frame.
Depending on the type of the clipping frame you have chosen, CDVIEW will issue either one of the following messages:
and then call either the BOX or CIRCLE command to create the required clipping frame.
After the creation of clipping frame, CDVIEW will continue to prompt
asking you to specify the required magnification factor of the drawing and the location where the magnified result will be placed. CDVIEW will continue the prompt until you press the space bar to consent the current setup of the resulting frame. In the mean time, a dragging frame is provided and the current placement of the frame will also be displayed in the drawing. Both of them will be changed as the current magnification factor is changed.
When you finally press the space bar, CDVIEW will start creating the magnified drawing view in the designated place and clip it against the resulting frame. When it finishes, the command ends.
