Suppose XYZ data are in columns A, B, C, and you want to remove points whose distance is within 10 from the origin. It can be done as follows:
1. Add a column,and select Set Column Values, and set the column (set Recalculate as None):
Distance3D(col(A),col(B),col(C),0,0,0)<=10?1/0:col(C)
2. Then select Worksheet: Reduce Rows from Origin menu. And choose Delete rows with missing values as Reduce Method.
You can also use other tools in Origin, e.g. Worksheet Query.
In 9.0, even you can use Data Filter tool.
