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

Clipped Details View -- Circle-type/<Box-type>:

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:

** Please box the part of drawing for details view.


** Please circle the part of drawing for details view.

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

Details View -- <Scale(1.000)>/<View Center Location>:

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.


CDVIEW will duplicate and scale the drawing entities that fall within or crossed by the clipping frame to the new location, and then make a boundary trimming of these objects against the clipping frame. However, since there are entities not trimmable, such as Texts, Dimensions, Inserts and Symbols, you may have to modify the resulting view by yourself if necessary.

Special Notes:

The CDVIEW command is an external command provided by the TCL program file "CDVIEW.TCL" or "CDVIEW.TCA". Either file must be present in the COMMANDS sub-directory where the TwinCAD resides. If you can not issue CDVIEW command, you may solve the problem by copying the "CDVIEW.TCL" to the COMMANDS sub-directory.
