h2. Name
*bol* --- Border line
h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#FFFFAA}
*bol* \[_linewidth_\] \[*nrg*\] \[*sav*\] \[*tub*\] \[*col*\] \[*edge*\] \[*fang*\] \[*flat*\] \[*nodraw*\]
{panel}
h2. Description
Generate and draw a border line around a grid or a triangle structure. The border line may be used to outline the grid for display purposes, or it may be extracted as a separate dataset (argument *nrg*) for further use.
h2. Arguments
_linewidth_
{indent} Draw border line with line width _linewidth_ where _linewidth_ is \[1, 2, 3 ..\]. 1 is the thinnest line, one pixel in width.
{indent}
*nrg*
{indent} Apply no regridding (decimation) of the grid.
{indent}
*col* red \| blu \| gre \|pin \| tur \| yel \| whi \| bla \| bro
{indent} Display the border line in color red / blue / green / pink / turquoise / yellow / white / black / brown
{indent}
*sav*
{indent} Save the border line in workspace \^bol. Make it active by *mlo \^bol*. The saved border line contains many cells or line pieces. To sort the line pieces together into a continuous line do the command [mak sortpl - Make sorted and connected polyline|ref:mak - Make datasets#mak sortpl]. This is necessary if one wants the border to be one consecutive line.
{indent}
*tub* \[_factor_\]
{indent} Display border line as a tube. The _factor_ is a number larger than 0, relative to 1 (default), giving the thickness of the tube.
{indent}
*edge*
{indent} Display internal and external edges of the dataset.
{indent}
*fang* _feature_angle_
{indent} Controls the edge finding property. _feature_angle_ is ...? The old Geocap logo uses fang 60.
{indent}
*flat* _level_
{indent} The border line result is displayed at z-level _level_. E.g. *bol flat 200* will display the border line at z=200.
{indent}
*nodraw*
{indent} No display of border result. Often used with argument *sav*, where the border line is saved in a workspace.
