Importing / Exporting Points
Export or Import points to / from CMM-Manager is possible using the Import Points or Export Raw Data Functions. You could even export points from one program and then import points into another. This might be done if you want to use variable for a Best Fit Alignment that are based on the previous measurement of a part or fixture for example. Or... Points could be exported / imported for re-constructing features from a previously run program.
1) In the first program, export the features using Import/Export>Export(group)>Export Raw Data. Choose the IQ-FormFit option, specify the path and filename and click okay.
2) In the next program you can import the same points using Import/Export>Import(group)>Import Points. Choose the file that was exported from the initial program, specify ascii format, units and check the delete file option.
When run in sequence the first program will export points and the second will import the same points and then delete the data file automatically.

There are several acceptable formats for imported point data. This file is simply an ASCII text file with file extension .DAT.
It could be as simple as a list of XYZ values:
0.375,0.3375,0.0
0.8125,0.8125,0.0
0.375,0.8125,0.0
Or a more complex file that splits points into logical groups (clouds), including point names and IJK values.
$name Top_Surface
T1,0.375,0.3375,0.0,0,0,1
T2,0.8125,0.8125,0.0,0,0,1
T3,0.375,0.8125,0.0,0,0,1
$name Left_Surface
L1,0.0,0.25,-0.25,-1,0,0
L2,0.0,0.375,-0.25,-1,0,0
L3,0.0,0.25,-0.625,-1,0,0
Here is the spec for the file structure -
Required
/ [
optional
]
[Cloud Name]
[Point Name], X, Y, Z , , [J], [K]
[Point Name], X, Y, Z, , [J], [K]
[Cloud Name]
[Point Name], X, Y, Z, , [J], [K]
[Point Name], X, Y, Z, , [J], [K]
Cloud Name - "$name " followed by text string (optional)
Point Name - text string (optional)
X,Y,Z - xyz coord value (required)
I,J,K - ijk vector value (optional)
This import format is common between Import Points and Import CAD Points
