::hwat::io::ReadMWF

Read the MWF and create return formatted list for processing.

Syntax

::hwat::io::ReadMWF str_weldFileLocation

Arguments

str_weldFileLocation: The MWF file’s whole path.

Returns

Success: Formatted data list; {str_id {thickness n_thick x d_x y d_y z d_z i d_i j d_j k d_k pidList {str_pidList}}}
Failure: {}

Example

::hwat::utils:: ReadMWF /homes/software/weldFile.txt

Comments

The format of the file being read is as follows:

#Point Id::    T::          X::          Y::          Z::        I::        J::        K::  PID1::  PID2::  PID3::  PID4::

For example:

{1 {thickness 2 x 99.3 y 234.23 z 456.0 i 0.0 j 1.0 k 0.0 pidList {6004 6005}} \
2 {thickness 0 x 99.3 y 234.23 z 456.0 i 0.0 j 1.0 k 0.0 pidList {}} \
3 {thickness 3 x 99.3 y 234.23 z 456.0 i 0.0 j 1.0 k 0.0 pidList {6004 6005 6007}}}
