h2. Name

*rcd* --- Read from cursor and draw

h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#ffffaa}

*rcd* \[*liw*] \[*poi*] \[*col*] \[*max | min | hei*] \[*sav*] \[*tub*] \[*dva*] \[*noy*] \[*chc*] \[*lco*] \[*set*]

{panel}

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.
{tip} 

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

h2. Arguments

*liw* _line\_width_ 
{indent}Digitize with _line\_width_ ( 1 / 2 / 3 / ...). 
{indent}

*tub*
{indent}Display the digitized line in tube mode. 
{indent}

*min* | *max*
{indent}Digitize with height = @zmin | @zmax. 
{indent}

*hei* _height_
{indent}Digitize with height (z-value) set to _height_. 
{indent}

*col* _color_
{indent}Apply color _color_ (_color_ = red | gre | blu |...) when digitizing. 
{indent}

*poi* \[*lin*]
{indent}Display only the points. *lin* means display also lines. 
{indent}

*dva*
{indent}Display value of the points. 
{indent}

*sav* _workspace\_name_
{indent}Save digitized data in workspace _workspace\_name_ in addition to workspace *^rcd*. 
{indent}

*noy*
{indent}The *noy* argument will disable the *y* key while digitizing. Ending the digitizing will enable the *y* key.
{indent}

*chc* \[*whi | red | gre ...*] | _r g b_
{indent}The *chc* argument will change the color when digitizing. 
{indent}

*lco*
{indent}Digitize using local origo and double precision.
{indent}

*set* \[*cir*] \[*cno*] \[*hei*] \[*dva*] \[*col*] \[*oll*] \[*all*] \[*crossing*]
{indent}
Options that can be *set* before or during digitizing.

*cir* \[*col* | *rad* _radius_] - Digitize and display a circle at digitizing position. Use *col red|gre...etc*. *rad* will set circle radius to _radius_.

*cno* \[*on|off*] - connect exclusively to nearest point in *active*. *off* will disconnect.

*hei* _heightvalue_ - Digitize using z coordinate _heightvalue_ .

*dva* \[*on|off*] - Display z value during digitizing.

*col whi|red|gre ...* - Specify color of the digitizing line.

*oll* - Use special *s m c hotkeys* in _outer limit line_ digitizing.

*all* - Use special *s m c hotkeys* in all digitizing.

*crossing* _value_ - Determines what will happen when digitizing picks up the crossing point of two lines.

{info:title=Options in z value when digitizing picks up the crossing point of two lines}
			0: no action. 
			1: use z value from active line (default)
			2: use z value from crossing line
			3: use the middle value as z value
			4: use lowest z value as z value
			5: use highest z value as z value
