PRIMER 22.1

B.iv. The Dummy Angles File (.daf)

Appendix B.iv: The Dummy Angles File (.daf)

From release 9.3RC1 onwards PRIMER can read and write "Dummy Angle" files, extension .daf.

The following formatting rules apply:

  • These are simple ASCII files, intended to be editable by hand if required.
  • All lines starting with $ , % or # are treated as comment lines.
  • All numerical data is in free format, however each section of data should be on a single line.
  • All angles are in degrees, and should be in the range +/-180.0

The file format is: (note that this format evolved during release 9.3 development, see Format Changes below for details)

$ Dummy Angles File. Generated on <current date>
$ Model title: <current model title>

<... any number of comment lines starting with $, % or # ...>

These comment lines are remembered, and will be copied to any newly written file for this model.
All comment lines up to, but not including, the " $ H-Point ... " line are saved.

The H-Point location. Note that its "label" field is always zero.
$ H-Point X position Y position Z position
0
<X coord>
<Y coord>
<Z coord>

The "whole dummy" angles. Note that their label field is always -1.

$ Whole Dummy X Angle Y Angle Z Angle
-1
<Theta X>
<Theta Y>
<Theta Z>

Then each assembly's title, label and angles are listed.

  • These do not have to appear in numerical order, although this is recommended for clarity.
  • The title is a comment line for ease of reading: it is ignored when the file is read, and need not match the existing title of assembly <n>
  • If an assembly does not have an angle specified in this file its current angle will not be changed when the file is read.
$ Assembly #1 title
1
<Theta X>
<Theta Y>
<Theta Z>
$ Assembly #2 title
2 <Theta X> <Theta Y> <Theta Z>

And so on for all assemblies in the Dummy

Here is an example of an actual file:
