h2. Description

*rcd* is used for digitizing both in 2D and 3D. It will read data by cursor-clicks on the left mouse button. The zoom (right) and pan (middle) mouse buttons can be used while digitizing.

When digitizing is ended, the result will be a dataset, usually present both in workspace *^rcd* and as the active dataset. Check the [ug: Keyboard Shortcuts] in the [User Guide|ug:] to learn what keys can be used for digitizing.

{tip:title=Tip}
The digitizing functionality has a front-end in the Quick digitizing, found under Tools.

There are many alternative digitizers present in Geocap. The command edit, !att:_img_icon2^Edit points and lines.png! is one examle, other examples are the Shelf functionality for digitizing outer limits, the command Red snapper, !att:_img_icon2^Red snapper.png! and seismic interpretation.

Use *[acd - Append data from cursor]* to append instead of digitizing from scratch.
