del — Delete point(s) and cell(s)

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

*del* \[*all | num | cel | cli | dis | dsp | lin | nocle | rep | rpp | spl | upd | poi*] \[*xy | xyz*] 

*del fd* _fielddataname_   ; # deleting field data 

{panel}

h2. Description

Delete operation in a polydata set. Will delete points or cells in polydata. Can also delete field data. 

h2. Arguments

{indent}No argument. Delete point closest to cursor position.{indent} 
*all* 
{indent}Delete all multiple points.{indent} 
*num* _number_ 
{indent}Delete point number _number_.{indent} 
*cel* \[_number_ | *lt | gt | nr | rep | undo*] 
{indent}Delete cell actions.{indent} 
{indent}{indent}•NoNo arguments. Delete a whole cell closest to the cursor position. 
•number_number_ - Delete cell number _number_. 
•lt*lt | gt* _distance_ - Delete cells lower | greater (longer) than _distance_. 
•lt*lt | gt* _number\_of\_points_pointsnr *nr*- Delete cells with less | more than _number\_of\_points_ points. Observe the *nr* syntax at the end. 
•rep*rep* - Cell elements are delete for every cursor pick (use 'p' or work in 2D mode by clicking). 
•undo*undo* - Undo last delete cell action.{indent}{indent} 
cli 
{indent}Delete a cell by a crossing line made by two cursor positions. {indent}
dis 
{indent}Display a marker at the deleted point.{indent} 
dsp 
{indent}Delete nearest point and split the line in two cells. {indent}
lin 
{indent}Delete a whole line closest to the cursor.{indent} 
nocle 
{indent}Delete nearest point with 'no clean'. This means sequential delete will update the graphics until the command mak cle, to clean up everything.{indent} 
poi 
{indent}Delete a single point with an alternative algorithm. Will create an immediate update of the dataset. Redisplay the data before continuing.{indent} 
rep 
{indent}Points are delete for every cursor pick (use keyboard p).{indent} 
rpp 
{indent}Mark the point for later delete. del upd will delete the points at the end.{indent} 
spl 
{indent}Split the line in two cells after the nearest point.{indent} 
upd 
{indent}Will delete points marked by rpp. Usefull for large datasets.{indent} 
xy | xyz 
{indent}Use 2D or 3D search for xy or xyz coordinates. 3D is default.{indent} 
fd fielddataname 
{indent}Delete field data of name fielddataname.{indent}
