# 3dtopos(1)

produce a .pos file from a .3d file

## NAME

3dtopos - produce a .pos file from a .3d file

## SYNOPSIS

**3dtopos** \[ **options** \] **.3d file** \[ **.pos file** \]

## DESCRIPTION

3dtopos takes a *.3d* file and produces a *.pos* file which contains a list of all the stations with coordinates (ordered x,y,z \[East, North, Up\]) and complete names.

The stations are sorted such that numbers occur in the correct order (so \`\`2'' before \`\`10'').  3dtopos even sorts numbers with a prefix and/or suffix, so you'd get:

```
040.sv8
040.sv8a
040.sv8b
040.sv8c
040.sv9
040.sv10
040.sv11
40_entrance_tag
40b_entrance_tag
```

You can also export *.pos* files from aven in versions 1.2.19 and later.
