Import Points from File (3D)
Point Cloud Design
Tool Bar 
Icon (Part Level)
Use this command to import points from an
ASCII file.
The point file is imported based on the default part units. Use
the Part
Settings Form to modify the part units if desired before importing
the point file.
Format for Point Import from an ASCII File
The <group_label> and the z coordinates are optional. When you enter a group label, only points from that group are imported. The file may contain comments preceded by a pound sign (#).
Delimiter
Specify the delimiter format of the imported point cloud file. Comma and Space are currently supported.
Group
Specify the group label of the points to insert if desired.
Create point block
Check this box to create a 3D block of the imported point cloud. This is a more compact form for storing the point data. Block is listed on the Pick Filter list for move, erase, blank and inquire commands.

Reduce point set
Check this box to reduce the total number of points used from the point cloud file and enter a tolerance value (see below). Up to 50 million points can be handled for reduction.
Tolerance
This command spatially sorts points and keeps only one point in each tolerance-sized region. If the tolerance is set to zero or left blank, then a guess is made at a reasonable tolerance. In a sample point file, a tolerance of 0.01 reduced the total number of points by 85% (from 17,697 to 2,761). However, fewer points mean less accuracy but greater system performance. For lower tolerances, use the Create point block option above.
VX stores the contents of the point file with the feature. The stored data is updated every time the part is regenerated. If the file is lost or corrupted, a record of the last data that was read from the file is always available for regenerating the part.
