How to set the pos parameter in the geom label?

[wukongwong]

For example, in the file body_035_power_drill.xml

<geom class="ycb_viz" mesh="035_power_drill" pos="0.014 0.014 0.002" material="035_power_drill"/>
<geom class="ycb_col" type="mesh" mesh="035_power_drill" size=".1 .1" pos="0.014 0.014 0.002" mass="0.895"/>

I do not know how to set the pos inside it. If I have a different object in the YCB dataset, then could you tell me how to set pos and euler? Thank you.
