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}No arguments. Delete a whole cell closest to the cursor position. 
_number_ - Delete cell number _number_. 
*lt | gt* _distance_ - Delete cells lower | greater (longer) than _distance_. 
*lt | gt* _number\_of\_points_ *nr*- Delete cells with less | more than _number\_of\_points_ points. Observe the *nr* syntax at the end.

*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}
